1. Why am I using CELAPRAM?

CELAPRAM contains the active ingredient citalopram hydrobromide. CELAPRAM belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). They are thought to work by acting on chemicals in your brain called amines. These amines are involved in controlling mood.

CELAPRAM is used to treat depression.

Depression is longer lasting or more severe than the "low moods" everyone has from time to time due to the stress of everyday life. It is thought to be caused by a chemical imbalance in parts of the brain. This imbalance affects your whole body and can cause emotional and physical symptoms such as feeling low in spirit, loss of interest in activities, being unable to enjoy life, poor appetite or overeating, disturbed sleep, often waking up early, loss of sex drive, lack of energy and feeling guilty over nothing.

CELAPRAM corrects this chemical imbalance and may help relieve the symptoms of depression.

Ask your doctor if you have any questions about why CELAPRAM has been prescribed for you.

Your doctor may have prescribed CELAPRAM for another reason.

2. What should I know before I use CELAPRAM?

Warnings

Do not use CELAPRAM if:

  • you have a condition called 'congenital long QT syndrome. At high doses, CELAPRAM can cause changes in the way that your heart beats. See your doctor immediately if you experience an irregular heartbeat, shortness of breath, dizziness or fainting while taking CELAPRAM.
  • you are allergic to citalopram hydrobromide, or any of the ingredients listed at the end of this leaflet.
  • Always check the ingredients to make sure you can use this medicine.
  • the packaging shows signs of tampering or the tablets do not look quite right.

Check with your doctor if you:

  • take any medicines for any other condition
  • you have allergies to any other substances such as foods, preservatives, or dye. Symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing, swelling of the face, lips, tongue or other parts of the body, or rash, itching or hives on the skin.
  • Are lactose intolerant, as CELAPRAM tablets contain lactose.

If you have, or have had any of the following medical conditions, tell your doctor before starting CELAPRAM

  • Congenital long QT syndrome or other heart conditions. Your doctor may occasionally need to check your heart beat and rhythm with an ECG test
  • illnesses which require you to have regular blood test
  • A tendency to bleed or bruise easily
  • bipolar disorder (manic depression)
  • diabetes
  • a history of seizures or fits
  • liver disease
  • kidney disease
  • restlessness and/or a need to move often
  • raised intraocular pressure (fluid pressure in the eye), or if you are a risk of angle-closure glaucoma.
  • epilepsy
  • you are receiving electroconvulsive therapy.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

Citalopram has been shown to reduce the quality of sperm in animal studies, which theoretically could affect fertility. If you are intending to start a family, ask your doctor for advice.

Do not take CELAPRAM if you are pregnant unless you and your doctor have discussed the risks and benefits involved.

Make sure your doctor and/or midwife know you are on CELAPRAM.

When taken during pregnancy, particularly in the last three months of pregnancy, medicines like CELAPRAM may affect the general condition of your newborn baby and may increase the risk of a serious condition in babies, called persistent pulmonary hypertension of the newborn (PPHN), making the baby breathe faster and appear bluish. These symptoms usually begin during the first 24 hours after the baby is born. If this happens to your baby you should contact your doctor and/or midwife immediately.

If you take CELAPRAM near the end of your pregnancy there may be an increased risk of heavy vaginal bleeding shortly after birth, especially if you have a history of bleeding disorders. Your doctor or midwife should be aware that you are taking CELAPRAM so they can advise you.

If used during pregnancy CIPRAMIL should never be stopped abruptly.

Ask your doctor or pharmacist for advice before taking any medicine.

Do not take CELAPRAM if you are breast-feeding unless you and your doctor have discussed the risks and benefits involved.

It is not recommended that you breast-feed while taking CELAPRAM as it is excreted in breast milk.

CELAPRAM use in children and adolescents

Do not give CELAPRAM to a child or adolescent.

There is no experience with its use in children or adolescents under 18 years old.

CELAPRAM use in the elderly

CELAPRAM can be given to elderly patients over 65 years of age with a reduced dose.

The effects of CELAPRAM in elderly patients are similar to that in other patients.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Do not take CIPRAMIL at the same time as the following other medicines:

  • pimozide, a medicine used to treat mental disorders
  • monoamine oxidase inhibitors (MAOIs), which are also used for the treatment of depression.
  • monoamine oxidase inhibitors such as selegiline which is used in the treatment of Parkinson's Disease
    - Do not take CELAPRAM when you are taking a MAOI or when you have been taking a MAOI within the last 14 days.
    - Taking CELAPRAM with MAOIs may cause a serious reaction with a sudden increase in body temperature, extremely high blood pressure and severe convulsions. Your doctor will know when it is safe to start CELAPRAM after the MAOI has been stopped.
  • the antibiotic linezolid
    - Do not take CELAPRAM when you are taking the antibiotic linezolid, or have recently stopped taking linezolid in the last 14-days.

Some medicines may interfere with CELAPRAM and affect how it works. These include:

  • monoamine oxidase inhibitors (MAOIs), medicines used to treat depression. Do not take CELAPRAM with MAOIs. CELAPRAM can only be started after you have stopped taking:
    - tranylcypromine and phenelzine for at least 14 days
    - moclobemide for at least 1 day
  • other antidepressants, including other SSRIs and tricyclic antidepressants such as imipramine, despiramine
  • medicines used to treat mental illnesses such as schizophrenia, depression and mood swings, including antipsychotics and lithium
  • linezolid, an antibiotic
  • Non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin, which are used to treat both pain and inflammation
  • sumatriptan, a medicine used to relieve migraines
  • tryptophan, an amino acid found in sports and dietary supplements
  • ketoconazole, itraconazole, fluconazole, medicines taken to treat fungal infections
  • macrolide antibiotics such as erythromycin and clarithromycin
  • warfarin, a medicine used to prevent blood clots
  • carbamazepine, a medicine used to treat convulsions
  • cimetidine and omeprazole, medicines used to treat reflux and stomach ulcers
  • St John's Wort (Hypericum perforatum), a herbal remedy used for depression
  • tramadol, a medicine used for pain relief
  • selegiline, a medicine used to treat Parkinson's disease
  • beta-blockers, medicines used to treat high blood pressure and other heart problems such as metoprolol
  • antiarrhythmics, medicines used to treat an irregular heart beat
  • digoxin, a medicine used to treat heart failure or to control a fast irregular heart beat
  • any other medicines for depression, anxiety, obsessivecompulsive disorder or pre-menstrual dysphoric disorder.

These medicines may be affected by CELAPRAM or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines. Your doctor will advise you.

Some combinations of medicines may increase the risk of serious side effects and are potentially life threatening.

Drugs that are known to affect the way the heart beats (for example some heart medicines, antibiotics, asthma medicines, antihistamines) should be avoided while taking CELAPRAM. If it is necessary for you to be on these medicines at the same time as CELAPRAM, your doctor may perform an ECG test to check your heart rate and rhythm.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking CELAPRAM.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect CELAPRAM.

4. How do I use CELAPRAM?

How much to take

  • The dose varies from person to person.
  • The standard dose for adults for this medicine is between 20 mg and 40 mg (one to two tablets) per day.
  • Your doctor may gradually increase this dose depending on how you respond to this medicine.
  • The recommended starting dose in elderly patients is 10 mg (half a tablet) per day but may be increased to a maximum of 20 mg (one tablet) per day by your doctor if needed.
  • If you have liver problems, or are taking medicines such as cimetidine or omeprazole, the recommended starting dose is 10mg (half a tablet) per day. The dose can be increased to a maximum of 20mg (one tablet) per day.
  • Your doctor may have prescribed a different dose. If you have been prescribed or are currently taking doses of CELAPRAM greater than 40mg, talk to your doctor about reducing the dose.
  • Follow all directions given to you by your doctor and pharmacist carefully.
  • They may differ from the information contained in this leaflet.
  • If you do not understand the instructions on the pack or bottle, ask your doctor or pharmacist for help.

When to take CELAPRAM

  • Take CELAPRAM at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you to remember when to take it.
  • CELAPRAM can be taken with or without food, either in the morning or evening.

How to take CELAPRAM

  • Swallow the tablets as a single daily dose with a glass of water.
CELAPRAM 20 mg and 40 mg tablets can be divided in half if advised by your doctor or pharmacist.

How long to take it

  • Continue to take CELAPRAM even if it takes some time before you feel any improvement in your condition.
Most medicines of this type take time to work, so do not be discouraged if you do not feel better right away. The treatment of depression may take at least six months.
  • Continue taking your medicine for as long as your doctor tells you, even if you begin to feel better.
  • The underlying illness may persist for a long time and if you stop your treatment too soon, your symptoms may return.
  • Do not stop taking this medicine suddenly.
  • If CELAPRAM is stopped suddenly you may experience mild, but usually temporary, symptoms such as dizziness, pins and needles, sleep disturbances (vivid dreams, inability to sleep), feeling anxious or agitated, headaches, feeling sick (nausea), vomiting, sweating, tremor (shaking), feeling confused, feeling emotional or irritable, diarrhoea, visual disturbances, or fast or irregular heartbeats.
  • When you have completed your course of treatment, the dose of CELAPRAM is gradually reduced over a couple of weeks rather than stopped abruptly.
  • Your doctor will tell you how to reduce the dosage so that you do not get these unwanted effects.

If you forget to use CELAPRAM

CELAPRAM should be used regularly at the same time each day. If you miss your dose at the usual time, and remember in less than 12 hours, take the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose you missed.

If you are not sure what to do or you have any questions about this, ask your doctor or pharmacist.

If you use too much CELAPRAM

If you think that you have used too much CELAPRAM, you may need urgent medical attention.

Symptoms of an overdose may include nausea (feeling sick), vomiting, dizziness, fast or slow heart beat or changes in heart rhythm, decreased or increased blood pressure, tremor (shaking), agitation, dilated pupils of the eyes, drowsiness, sleepiness, lethargy, sweating, blueish discolouration of the skin and an increase in rate of breathing. Convulsions or coma may occur. A condition called serotonin syndrome may occur with high fever, agitation, confusion, trembling and abrupt contractions of muscles.

You should immediately:

  • phone the Poisons Information Centre
    (Australia telephone 13 11 26) for advice, or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while using CELAPRAM?

Things you should do

Before starting any new medicine, tell your doctor or pharmacist that you are taking CELAPRAM.

Tell all the doctors, dentists and pharmacists who are treating you that you are taking CELAPRAM.

If you become pregnant while taking CELAPRAM, tell your doctor immediately.

Persons taking CELAPRAM may be more likely to think about killing themselves or actually trying to do so, especially when CELAPRAM is first started or the dose is changed. Tell your doctor immediately if you have thoughts about killing yourself or if you are close to or care for someone taking CELAPRAM who talks about or shows signs of killing him or herself.

Occasionally, the symptoms of depression may include thoughts of suicide or self-harm. It is possible that these symptoms continue or get worse until the full antidepressant effect of the medicine becomes apparent. This is more likely to occur in children, adolescents and young adults under 25 years of age, and you have not used antidepressant medicines before.

Contact your doctor or a mental health professional right away, or go to the nearest hospital for treatment if you or someone you know is showing any of the following warning signs of suicide:

  • worsening of your depression
  • thoughts or talk of death or suicide
  • thoughts or talk of self-harm or harm to others
  • any recent attempts of self-harm
  • increase in aggressive behaviour, irritability, agitation or any other unusual changes in behaviour or mood.

All mentions of suicide or violence must be taken seriously.

Family and carers of people taking CELAPRAM also need to monitor for the above symptoms.

Do not stop taking this medicine or change the dose without consulting your doctor, even if you experience increased anxiety at the beginning of treatment.

At the beginning of treatment, some patients may experience increased anxiety which will disappear during continued treatment.

Visit your doctor regularly so they can check on your progress.

If you plan to have surgery, including dental surgery, tell your doctor or dentist that you are taking CELAPRAM

Call your doctor straight away if you:

  • become pregnant while taking CELAPRAM. Do not stop taking your tablets until you have spoken to your doctor.
  • experience symptoms such as restlessness or difficulty in sitting or standing still.
These symptoms can occur during the first weeks of treatment.
  • experience episodes of mania. Some patients with bipolar disorder (manic depression) may enter into a manic phase. This is characterised by profuse and rapidly changing ideas, exaggerated gaiety and excessive physical activity.

Things you should not do

Do not use CELAPRAM to treat any other conditions unless your doctor tells you to.

Do not give CELAPRAM to anyone else, even if they have the same condition as you.

Do not suddenly stop taking CELAPRAM, or change the dose, without checking with your doctor.

Do not let yourself run out of CELAPRAM over weekends or holidays.

If you stop CELAPRAM suddenly, you may get unwanted side effects, such as dizziness, headache and nausea.

Your doctor will tell you how to gradually reduce the amount of CELAPRAM you are taking before stopping completely. This is usually done slowly over one to two weeks.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how CELAPRAM affects you.

CELAPRAM may cause dizziness, visual disturbances or drowsiness in some people. If you experience any of these, do not drive, operate machinery or do anything else that could be dangerous.

Drinking alcohol

Tell your doctor if you drink alcohol.

Avoid alcohol while you are taking this medicine.

It is not advisable to drink alcohol while you are being treated for depression.

Looking after your medicine

Follow the instructions in the carton on how to take care of your medicine properly.

Keep your tablets in the pack or bottle until it is time to take them. If you take the tablets out of the pack or bottle they may not keep well.

Store it in a cool dry place where the temperature stays below 25°C, away from moisture, heat or sunlight; for example, do not store it:

  • in the bathroom or near a sink, or
  • in the car or on window sills.

Keep it where young children cannot reach it.

A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Getting rid of any unwanted medicine

If you no longer need to use this medicine or it is out of date, take it to any pharmacy for safe disposal.

Do not use this medicine after the expiry date.

6. Are there any side effects?

All medicines can have side effects. If you do experience any side effects, most of them are minor and temporary. However, some side effects may need medical attention.

CELAPRAM helps most people with depression, but it may have unwanted side effects in some people.

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking CELAPRAM.

Do not be alarmed by this list of possible side effects.

4 Clinical Particulars

4.1 Therapeutic Indications

Treatment of major depression.

4.2 Dose and Method of Administration

Citalopram should be administered as a single daily dose. The dose may be taken in the morning or evening without regard for food.

Adults.

The starting dose is 20 mg/day. The dose can be increased in increments of 10 mg until satisfactory clinical response is achieved. The maximum dose is 40 mg/day. As the treatment result in general can be evaluated only after 2 to 3 weeks' treatment, a possible dose increase should take place with intervals of 2 to 3 weeks.

Elderly patients.

The starting dose is 10 mg/day. The dose can be increased by 10 mg to a maximum of 20 mg/day. As the treatment result in general can be evaluated only after 2-3 weeks' treatment, a possible dose increase should take place after an interval of 2-3 weeks.

Children and adolescents (< 18 years).

The efficacy and safety of citalopram for the treatment of major depressive disorder have not been established in this population. Citalopram should not be used in children and adolescents under the age of 18 years.

Reduced hepatic function.

An initial dose of 10 mg daily for the first two weeks of treatment is recommended in patients with mild or moderate hepatic impairment. The maximum recommended dose is 20 mg/day. Caution and extra careful dose titration is advised in patients with severely reduced hepatic function.

Reduced renal function.

Dosage adjustment is not necessary in patients with mild or moderate renal impairment. No information is available on treatment of patients with severely reduced renal function (creatinine clearance < 30 mL/min).

Poor metabolisers of CYP2C19 and patients taking CYP2C19 inhibitors.

An initial dose of 10 mg daily during the first two weeks of treatment is recommended for patients who are known to be poor metabolisers with respect to CYP2C19. The dose may be increased to a maximum of 20 mg daily depending on individual patient response (see Section 5.2 Pharmacokinetic Properties). Patients taking cimetidine or other CYP2C19 inhibitors should not exceed the maximum dose of 20 mg/day.

Duration of treatment.

In treating depression a treatment period of at least six months is usually necessary to provide adequate maintenance against the potential for relapse.

Withdrawal symptoms seen on discontinuation of SSRI.

Abrupt discontinuation should be avoided. When stopping treatment with citalopram the dose should be gradually reduced over a period of at least one to two weeks in order to reduce the risk of withdrawal reactions (see Section 4.4 Special Warnings and Precautions for Use). If intolerable symptoms occur following a decrease in the dose or upon discontinuation of treatment, then resuming the previously prescribed dose may be considered. Subsequently, the physician may continue decreasing the dose, but at a more gradual rate.

4.3 Contraindications

Hypersensitivity to citalopram and any excipients in Celapram (see Section 6.1 List of Excipients).
Congenital long QT syndrome (see Section 4.4 Special Warnings and Precautions for Use).

Monoamine oxidase inhibitors.

Citalopram should not be used in combination with monoamine oxidase inhibitors (MAOI) (including selegiline in daily doses exceeding 10 mg/day). Citalopram should not be used in combination with reversible MAOI (RIMA), moclobemide, or within 14 days of discontinuing treatment with a MAOI, and at least one day after discontinuing treatment with the reversible MAOI (RIMA), moclobemide. Similarly, at least 14 days should be allowed after stopping citalopram before starting a MAOI or RIMA. Cases of serious reactions, such as potentially life threatening serotonin syndrome (characterised by neuromuscular excitation, altered mental status and autonomic dysfunction) have been reported in patients receiving an SSRI in combination with a monoamine oxidase inhibitor (MAOI) or the reversible MAOI (RIMA), moclobemide, and in patients who have recently discontinued an SSRI and have been started on a MAOI (see Section 4.4 Special Warnings and Precautions for Use; Section 4.5 Interactions with Other Medicines and Other Forms of Interactions).

Linezolid.

Citalopram is contraindicated in combination with linezolid unless there are facilities for close observation and monitoring of blood pressure (see Section 4.5 Interactions with Other Medicines and Other Forms of Interactions).

Pimozide.

Concomitant administration of citalopram and pimozide is contraindicated due to the risk of QT interval prolongation (see Section 4.5 Interactions with Other Medicines and Other Forms of Interactions).

4.4 Special Warnings and Precautions for Use

Use with caution in the following circumstances.

QT prolongation and torsade de pointes.

Citalopram can cause a dose dependent increase in the QT interval and should not be dosed above 40 mg/day. Torsade de pointes has been reported postmarketing. Citalopram should not be used in patients with congenital long QT syndrome. Patients at higher risk of developing prolongation of the QT interval include those with congestive heart failure, bradyarrhythmias or a predisposition to hypokalaemia or hypomagnesaemia because of concomitant illness or drugs. Hypokalaemia and hypomagnesaemia should be corrected prior to initiation of treatment and periodically monitored. Consider more frequent ECG monitoring in these patients and those with other risk factors for QT prolongation. Dose escalations over 20 mg/day in elderly patients (> 65 years), patients with hepatic dysfunction, CYP2C19 poor metabolisers or patients taking concomitant cimetidine or another CYP2C19 inhibitor are not recommended.
The influence of citalopram on QT interval at doses of 20 mg and 60 mg per day was evaluated in a randomised, placebo and active (moxifloxacin 400 mg) controlled crossover, escalating multiple dose study in 119 healthy subjects. The change from baseline in QTc (Fridericia correction) was 7.5 msec at the 20 mg/day dose and 16.7 msec at the 60 mg/day dose.
Citalopram has not been systematically evaluated in patients with a recent history of myocardial infarction or unstable heart disease. Patients with these diagnoses were generally excluded from clinical studies during the product's premarketing testing.

Clinical worsening and suicide risk associated with psychiatric disorders.

The risk of suicide attempts is inherent in depression and may persist until significant remission occurs. The risk must be considered in all depressed patients.
Patients with depression may experience worsening of their depressive symptoms and/or the emergence of suicidal ideation and behaviour (suicidality), whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. As improvement may not occur during the first few weeks or more of treatment, patients should be closely monitored for clinical worsening and suicidality, especially at the beginning of a course of treatment or at the time of dose changes, either increases or decreases.
Consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medication, in patients whose depression is persistently worse or whose emergent suicidality is severe, abrupt in onset or was not part of the patient's presenting symptoms. Patients (and caregivers of patients) should be alerted about the need to monitor for any worsening of their condition and/or the emergence of suicidal ideation/behaviour or thoughts of harming themselves and to seek medical advice immediately if these symptoms present.
Patients with comorbid depression associated with other psychiatric disorders being treated with antidepressants should be similarly observed for clinical worsening and suicidality.
Patients with a history of suicide related events, or those exhibiting a significant degree of suicidal ideation prior to commencement of treatment, are at greater risk of suicidal thoughts or suicide attempts, and should receive careful monitoring during treatment.
Pooled analyses of 24 short-term (4 to 16 weeks), placebo controlled trials of nine antidepressant medicines (SSRIs and others) in 4,400 children and adolescents with major depressive disorder (16 trials), obsessive compulsive disorder (4 trials), or other psychiatric disorders (4 trials) have revealed a greater risk of adverse events representing suicidal behaviour or thinking (suicidality) during the first few months of treatment in those receiving antidepressants. The average risk of such events in patients treated with an antidepressant was 4%, compared with 2% of patients given placebo. There was considerable variation in risk among the antidepressants but there was a tendency towards an increase for almost all antidepressants studied. The risk of suicidality was most consistently observed in the major depressive disorder trials but there were signals of risk arising from the trials in other psychiatric indications (obsessive compulsive disorder and social anxiety disorder) as well. No suicides occurred in these trials. It is unknown whether the suicidality risk in children and adolescents patients extends to use beyond several months. The nine antidepressant medicines in the pooled analyses included five SSRIs (citalopram, fluoxetine, fluvoxamine, paroxetine, sertraline) and four non-SSRIs (bupropion, mirtazapine, nefazodone, venlafaxine).
Pooled analyses of short-term studies of antidepressant medications have also shown an increased risk of suicidal thinking and behaviour, known as suicidality, in young adults aged 18 to 24 years during initial treatment (generally the first one to two months). Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond the age of 24 years, there was a reduction with antidepressants compared to placebo in adults aged 65 years and older.
Symptoms of anxiety, agitation, panic attacks, insomnia, irritability, hostility (aggressiveness), impulsivity, akathisia (psychomotor restlessness), hypomania and mania have been reported in adults, adolescents and children being treated with antidepressants for major depressive disorder as well as for other indications, both psychiatric and nonpsychiatric. Although a causal link between the emergence of such symptoms and either worsening of depression and/or emergence of suicidal impulses has not been established, there is concern that such symptoms may be precursors of emerging suicidality.
Families and caregivers of children and adolescents being treated with antidepressants for major depressive disorder or for any other condition (psychiatric or nonpsychiatric) should be informed about the need to monitor these patients for the emergence of agitation, irritability, unusual changes in behaviour and other symptoms described above, as well as the emergence of suicidality, and to report such symptoms immediately to healthcare providers. It is particularly important that monitoring be undertaken during the initial few months of antidepressant treatment or at times of dose increase or decrease.
Prescriptions for Celapram should be written for the smallest quantity of tablets consistent with good patient management, in order to reduce the risk of overdose.

Monoamine oxidase inhibitors.

Simultaneous administration of citalopram and a monoamine oxidase inhibitor (MAOI) may cause serotonin syndrome, a serious, sometimes fatal, reaction in patients receiving an SSRI in combination with a MAOI and in patients treated with an SSRI and a MAOI in close temporal proximity. Some cases presented with features resembling neuroleptic malignant syndrome. Symptoms and signs of serotonin syndrome include: rapid onset, clonus, myoclonus, tremor, shivering, hyper-reflexia, hyperthermia, rigidity, autonomic instability with possible rapid fluctuations of vital signs and mental status changes that include extreme agitation progressing to delirium and coma.
Treatment with citalopram may be instituted 14 days after discontinuation of irreversible MAOIs and a minimum of one drug free day after discontinuation of moclobemide. Treatment with MAOIs may be introduced 14 days after discontinuation of citalopram.

Serotonergic medicines.

Citalopram should not be used concomitantly with medicinal products with serotonergic effects such as triptans (including sumatriptan and oxitriptan), opioids (including tramadol), and tryptophan.

Haemorrhage.

Bleeding abnormalities of the skin and mucous membranes have been reported with the use of SSRIs (including purpura, ecchymosis, haematoma, epistaxis, vaginal bleeding and gastrointestinal bleeding). SSRIs/SNRIs may increase the risk of postpartum haemorrhage (see Section 4.6 Fertility, Pregnancy and Lactation; Section 4.8 Adverse Effects (Undesirable Effects)). Citalopram should therefore be used with caution in patients concomitantly treated with oral anticoagulants, medicinal products known to affect platelet function (e.g. atypical antipsychotics and phenothiazines, most tricyclic antidepressants, acetylsalicyclic acid and nonsteroidal anti-inflammatory medicinal products (NSAIDs), ticlopidine and dipyridamole) as well as in patients with a past history of abnormal bleeding or those with predisposing conditions. Pharmacological gastroprotection should be considered for high risk patients.

Hyponatraemia.

Probably due to inappropriate antidiuretic hormone secretion (SIADH), has been reported as a rare adverse reaction with the use of SSRIs. Especially elderly patients seem to be a risk group.

Akathisia/psychomotor restlessness.

The use of SSRIs/SNRIs has been associated with the development of akathisia, characterised by a subjectively unpleasant or distressing restlessness and need to move often accompanied by an inability to sit or stand still. This is most likely to occur within the first few weeks of treatment. In patients who develop these symptoms, increasing the dose may be detrimental and it may be necessary to review the use of SSRIs/SNRIs.

Seizures.

Although animal experiments have shown that citalopram has no epileptogenic potential it should, like other antidepressants, be used with caution in patients with a history of seizures. Citalopram should be discontinued in any patient who develops seizures. Citalopram should be avoided in patients with unstable epilepsy and patients with controlled epilepsy should be carefully monitored. Citalopram should be discontinued if there is an increase in seizure frequency.

Diabetes.

As described for other psychotropics citalopram may modify insulin and glucose responses calling for adjustment of the antidiabetic therapy in diabetic patients; in addition the depressive illness itself may affect patients' glucose balance.

Mania.

A major depressive episode may be the initial presentation of bipolar disorder. It is generally believed that treating such an episode with an antidepressant alone can increase the likelihood of precipitation of a mixed/manic episode in patients at risk of bipolar disorder. Prior to initiating treatment with an antidepressant, patients should be adequately screened to determine if they are at risk for bipolar disorder; such screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder and depression.
SSRIs should be used with caution in patients with a history of mania/hypomania. SSRIs should be discontinued in any patient entering a manic phase.

ECT (electroconvulsive therapy).

There is little clinical experience of concurrent use of citalopram and ECT, therefore caution is advised.

Discontinuation/withdrawal.

Withdrawal symptoms when treatment is discontinued are common, particularly if discontinuation is abrupt.
The risk of withdrawal symptoms may be dependent on several factors including the duration and dose of therapy and the rate of dose reduction. Dizziness, sensory disturbances (including paraesthesia), sleep disturbances (including insomnia and intense dreams), agitation or anxiety, nausea and/or vomiting, tremor, confusion, sweating, headache, diarrhoea, palpitations, emotional instability, irritability and visual disturbances are the most commonly reported reactions. Generally these symptoms are mild to moderate; however, in some patients they may be severe in intensity.
They usually occur within the first few days of discontinuing treatment, but there have been very rare reports of such symptoms in patients who have inadvertently missed a dose.
Generally these symptoms are self limiting and usually resolve within 2 weeks, though in some individuals they may be prolonged (2-3 months or more). It is, therefore, advised that citalopram should be gradually tapered when discontinuing treatment over a period of several weeks or months, according to the patient's needs (see Section 4.2 Dose and Method of Administration).

Use in patients with cardiac disease.

Citalopram has not been evaluated or used to any appreciable extent in patients with a recent history of myocardial infarction or unstable heart disease. Like other SSRIs, citalopram causes a small decrease in heart rate. Consequently, caution should be observed when citalopram is initiated in patients with pre-existing slow heart rate.

Excipients.

The tablets contain lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not receive this medicine.

Angle-closure glaucoma.

Antidepressants including citalopram may have an effect on pupil size resulting in mydriasis. This mydriatic effect has the potential to narrow the eye angle resulting in increased intraocular pressure and angle-closure glaucoma, especially in pre-disposed patients. Citalopram should therefore be used with caution in patients with raised intraocular pressure and in those at risk of angle-closure glaucoma.

Use in hepatic impairment.

Citalopram is eliminated more slowly in patients with reduced hepatic function. The half-life of citalopram is about twice as long, and steady-state citalopram concentrations at a given dose will be about twice as high, as in patients with normal liver function.

Use in renal impairment.

Citalopram is eliminated more slowly in patients with mild to moderate reduction of renal function, without any major impact on the pharmacokinetics of citalopram.

Polymorphism.

There was no clinically relevant difference in the AUC between poor and extensive metabolisers with respect to CYP2D6 following administration of citalopram. The AUC for poor metabolisers with respect to CYP2C19 was less than 2-fold higher than the AUC observed in the extensive metabolisers (see Section 4.2 Dose and Method of Administration).

Use in the elderly.

Longer half-lives and decreased clearance values due to a reduced rate of metabolism have been demonstrated in elderly patients. Steady state mean values were about twice as high and ranged up to four times higher in the elderly than in younger patients treated with the same dose.

Paediatric use (< 18 years).

The efficacy and safety of citalopram for the treatment of major depressive disorder has not been established in children and adolescents less than 18 years of age. Consequently, citalopram should not be used in children and adolescents less than 18 years of age.

Effects on laboratory tests.

No data available.

4.5 Interactions with Other Medicines and Other Forms of Interactions

Drugs that prolong the QT interval.

More frequent ECG monitoring is recommended in patients on concomitant medications that prolong the QT interval (see Section 4.4 Special Warnings and Precautions for Use, QT prolongation and torsade de pointes).

MAOIs.

Monoamine oxidase inhibitors (MAOIs) should not be used in combination with SSRIs (see Section 4.3 Contraindications).
Cases of serious and sometimes fatal reactions have been reported in patients receiving an SSRI in combination with a monoamine oxidase inhibitor (MAOI), including the irreversible MAOI selegiline, the reversible MAOIs linezolid and moclobemide, and in patients who have recently discontinued SSRI and have been started on a MAOI.
Treatment with citalopram may be instituted 14 days after discontinuation of irreversible MAOIs and a minimum of one drug free day after discontinuation of moclobemide. Treatment with MAOIs may be introduced 14 days after discontinuation of citalopram.

Serotonin syndrome.

Development of serotonin syndrome may occur in association with treatment with SSRIs and SNRIs, particularly when given in combination with MAOIs or other serotonergic agents. Symptoms and signs of serotonin syndrome include rapid onset of neuromuscular excitation (hyper-reflexia, incoordination, myoclonus, tremor), altered mental status (confusion, agitation, hypomania) and autonomic dysfunction (diaphoresis, diarrhoea, fever, shivering and rapidly fluctuating vital signs). Treatment with citalopram should be discontinued if such events occur and supportive symptomatic treatment initiated.

Pimozide.

Coadministration of a single dose of pimozide 2 mg to subjects treated with racemic citalopram 40 mg/day for 11 days caused an increase in AUC and Cmax of pimozide, although not consistently throughout the study. The coadministration of pimozide and citalopram resulted in a mean increase in the QTc interval of approximately 10 msec. Due to the interaction noted at a low dose of pimozide, concomitant administration of citalopram and pimozide is contraindicated (see Section 4.3 Contraindications).

Selegiline (selective MAO-B inhibitor).

A pharmacokinetic/pharmacodynamic interaction study with concomitantly administered citalopram (20 mg daily) and selegiline (10 mg daily) (a selective MAO-B inhibitor) demonstrated no clinically relevant interactions. The concomitant use of citalopram and selegiline (in doses above 10 mg daily) is contraindicated (see Section 4.3 Contraindications).

Serotonergic drugs.

Co-administration with serotonergic drugs e.g. opioids (including tramadol), triptans (including sumatriptan and oxitriptan) may lead to enhancement of serotonergic effects. Similarly, Hypericum perforatum (St John's wort) should be avoided as adverse interactions have been reported with a range of drugs including antidepressants.

Hepatic enzymes.

The metabolism of citalopram is only partly dependent on the hepatic cytochrome P450 isozyme CYP2D6 and, unlike some other SSRIs, citalopram is only a weak inhibitor of this important enzyme system which is involved in the metabolism of many drugs (including antiarrhythmics, neuroleptics, beta-blockers, tricyclic antidepressants and some SSRIs).
In vitro enzyme inhibition data did not reveal an inhibitory effect of citalopram on CYP3A4, but did suggest that it is a weak inhibitor of CYP1A2, 2D6 and 2C19. Citalopram would be expected to have little inhibitory effect on in vivo metabolism mediated by these isoenzymes. However, in vivo data to address this question are very limited.
Citalopram steady state levels were not significantly different in poor metabolisers and extensive 2D6 metabolisers after multiple dose administration of citalopram, suggesting that coadministration, with citalopram, of a drug that inhibits CYP2D6, is unlikely to have clinically significant effects on citalopram metabolism.
Since CYP3A4 and 2C19 are the primary enzymes involved in the metabolism of citalopram, it is expected that potent inhibitors of 3A4 (e.g. ketoconazole, itraconazole, and macrolide antibiotics) and potent inhibitors of CYP2C19 (e.g. omeprazole, fluconazole, and cimetidine) might decrease the clearance of citalopram. Citalopram 20 mg/day is the maximum recommended dose for patients taking concomitant cimetidine or another CYP2C19 inhibitor because of the risk of QT prolongation (see Section 4.2 Dose and Method of Administration).

Lithium and tryptophan.

There have been reports of enhanced serotonergic effects when SSRIs have been given with lithium or tryptophan and therefore the concomitant use of SSRIs with these drugs should be undertaken with caution. A pharmacokinetic interaction study of lithium and citalopram (N=8) did not reveal any pharmacokinetic interactions (see also above).

Imipramine and other tricyclic antidepressants (TCAs).

In a pharmacokinetic study, no effect was demonstrated on either citalopram or imipramine levels, although the level of desipramine, the primary metabolite of imipramine, was increased. The clinical significance of the desipramine change is unknown. Nevertheless, caution is indicated in the coadministration of citalopram and tricyclic antidepressants.

Medicines affecting the central nervous system.

Given the primary CNS effects of citalopram, caution should be used when it is taken in combination with other centrally acting drugs.

Medicines lowering the seizure threshold.

SSRIs can lower the seizure threshold. Caution is advised when concomitantly using other medicinal products capable of lowering the seizure threshold (e.g. antidepressants (tricyclics, SSRIs), neuroleptics (phenothiazines, thioxanthenes, butyrophenones), mefloquine, bupropion and tramadol).

Digoxin.

In subjects who had received 21 days of 40 mg/day citalopram, combined administration of citalopram and digoxin (single dose of 1 mg) did not significantly affect the pharmacokinetics of either citalopram or digoxin.

Carbamazepine.

Combined administration of citalopram (40 mg/day for 14 days) and carbamazepine (titrated to 400 mg/day for 35 days) did not significantly affect the pharmacokinetics of carbamazepine, a CYP3A4 substrate. Although trough citalopram plasma levels were unaffected, given the enzyme inducing properties of carbamazepine, the possibility that carbamazepine might increase the clearance of citalopram should be considered if the two drugs are coadministered.

Metoprolol.

A pharmacokinetic interaction between citalopram and metoprolol was observed, resulting in a twofold increase in metoprolol concentrations. The change in metabolism of metoprolol suggests an interaction between metoprolol and demethylcitalopram related to the CYP2D6 isoenzyme. There was no statistically significant increase in the effect of metoprolol on blood pressure and heart rate in healthy volunteers by adding citalopram.

Cimetidine.

Cimetidine caused a moderate increase in the average steady state levels of citalopram. Citalopram 20 mg/day is the maximum recommended dose for patients taking concomitant cimetidine because of the risk of QT prolongation.

Alcohol.

The combination of SSRIs and alcohol is not advisable.

Medicines that interfere with haemostasis (NSAIDs, aspirin, warfarin, etc).

Serotonin release by platelets plays an important role in haemostasis. There is an association between use of psychotropic drugs that interfere with serotonin reuptake and the occurrence of abnormal bleeding. Concurrent use of an NSAID, aspirin or warfarin potentiates the risk. Thus, patients should be cautioned about using such medicines concurrently with Celapram.

Others.

No pharmacodynamic interactions have been noted in clinical studies in which citalopram has been given concomitantly with benzodiazepines, neuroleptics, analgesics, lithium, alcohol, antihistamines, antihypertensive drugs, beta-blockers and other cardiovascular drugs.
Experience with citalopram has not revealed any clinically relevant interactions with neuroleptics with the exception of pimozide (see Section 4.3 Contraindications; Section 4.5 Interactions with Other Medicines and Other Forms of Interactions, Pimozide). However, as with other SSRIs, the possibility of a pharmacodynamic interaction cannot be excluded.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

In rats, female fertility was unaffected by oral treatment with citalopram doses which achieved plasma drug concentrations slightly in excess of those expected in humans, but effects on male rat fertility have not been tested with adequate oral doses.
Animal data have shown that citalopram induces a reduction of fertility index and pregnancy index, reduction in number in implantation and abnormal sperm.
Animal data have shown that citalopram may affect sperm quality.
(Category C)
Limited clinical data are available regarding exposure to citalopram during pregnancy.
Reproduction studies performed in rats and rabbits at oral doses of up to 112 and 32 mg/kg, respectively, have revealed no evidence of teratogenic effects. Studies in rats have shown increased postimplantation loss, reduced foetal weight and foetal developmental changes. A no effect oral dose of 56 mg/kg/day was established for foetal development. There are no adequate and well controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
Neonates should be observed if maternal use of citalopram had continued into the later stages of pregnancy, particularly into the third trimester. If citalopram is used until or shortly before birth, discontinuation effects in the newborn are possible. Abrupt discontinuation should be avoided during pregnancy.
Neonates exposed to citalopram, other SSRIs (selective serotonin reuptake inhibitors) or SNRIs (serotonin noradrenaline reuptake inhibitors) late in the third trimester have developed complications requiring prolonged hospitalisation, respiratory support and tube feeding. Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnoea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycaemia, hypotonia, hypertonia, hyper-reflexia, tremor, jitteriness, irritability, lethargy, constant crying, somnolence and difficulty sleeping. These features are consistent with either a direct toxic effect of SSRIs and SNRIs or, possibly, a drug discontinuation syndrome.
Epidemiological studies have shown that the use of SSRIs (including citalopram) in pregnancy, particularly use in late pregnancy, was associated with an increased risk of persistent pulmonary hypertension of the newborn (PPHN). The risk of PPHN among infants born to women who used SSRIs late in pregnancy was estimated to be 4 to 5 times higher than the rate of 1 to 2 per 1000 pregnancies observed in the general population.
Observational data indicate an increased risk (less than 2-fold) of postpartum haemorrhage following SSRI/SNRI exposure within the month prior to birth (see Section 4.4 Special Warnings and Precautions for Use; Section 4.8 Adverse Effects (Undesirable Effects)).
Citalopram appears in human breast milk in very low concentrations. In breastfeeding mothers, caution is recommended as it is not known whether citalopram excreted in milk may affect the infant.

4.7 Effects on Ability to Drive and Use Machines

Patients who are prescribed psychotropic medication may be expected to have some impairment of general attention and concentration and should be cautioned about their ability to drive a car and operate machinery.

4.8 Adverse Effects (Undesirable Effects)

Adverse effects observed with citalopram are in general mild and transient. They are most frequent during the first one or two weeks of treatment and usually attenuate subsequently.
The most commonly observed adverse events associated with the use of citalopram in double blind, placebo controlled trials and not seen at an equal incidence among placebo treated patients were: nausea, somnolence, dry mouth, increased sweating, tremor, diarrhoea and ejaculation disorder. The incidence of each in excess over placebo is low.
In comparative double blind clinical trials with tri and tetracyclic antidepressants (TTCAs), the incidence of 10 adverse events was statistically significantly higher on TTCAs (dry mouth, increased sweating, constipation, tremor, dizziness, somnolence, abnormal accommodation, postural hypotension, palpitation, perverted taste) compared to citalopram. For two events (nausea, ejaculation disorder) the incidence was statistically higher on citalopram compared to TTCAs.
In the comparative trials versus other SSRIs, no statistically significant differences between the groups were found.
Adverse events reported in clinical trials with citalopram treated patients include (see Table 1):

Dose dependency of adverse events.

The potential relationship between the dose of citalopram administered and the incidence of adverse events was examined in a fixed dose study in depressed patients receiving placebo or citalopram 10, 20, 40, and 60 mg. Jonckheere's trend test revealed a positive dose response (p < 0.05) for the following adverse events: fatigue, impotence, insomnia, sweating increased, somnolence, and yawning.

Male and female sexual dysfunction with SSRIs.

While sexual dysfunction is often part of depression and other psychiatric disorders, there is increasing evidence that treatment with selective serotonin reuptake inhibitors (SSRIs) may induce sexual side effects. This is a difficult area to study because patients may not spontaneously report symptoms of this nature, and therefore, it is thought that sexual side effects with the SSRIs may be underestimated. In placebo controlled clinical trials (see Table 1), the reported incidence of decreased libido for the whole population was 2.5%; ejaculation disorder (primarily ejaculatory delay), and impotence in male depressed patients receiving citalopram (N = 423) was 5.9%, and 2.8%, respectively. In female depressed patients receiving citalopram (N = 660), the reported incidence of anorgasmia was 0.5%. The reported incidence of decreased libido was 0.4% among depressed patients receiving placebo, whilst sex specific adverse events were not reported among male and female depressed patients receiving placebo.
While it is difficult to know the precise risk of sexual dysfunction associated with the use of SSRIs, physicians should routinely inquire about such possible side effects.

Vital sign changes.

Citalopram and placebo groups were compared with respect to: (1) mean change from baseline in vital signs (pulse, systolic blood pressure and diastolic blood pressure); and (2) the incidence of patients meeting criteria for potentially clinically significant changes from baseline in these variables. These analyses did not reveal any clinically important changes in vital signs associated with citalopram treatment.

Mydriasis and angle-closure glaucoma.

Cases of mydriasis and angle-closure glaucoma have been reported in the post-marketing period (see Section 4.4 Special Warnings and Precautions for Use).

Weight changes.

Patients treated with citalopram in controlled trials experienced a weight loss of about 0.5 kg compared to no change for placebo patients.

Laboratory changes.

Citalopram and placebo groups were compared with respect to: (1) mean change from baseline in various serum chemistry, haematology and urinalysis variables; and (2) the incidence of patients meeting criteria for potentially clinically significant changes from baseline in these variables. These analyses revealed no clinically important changes in laboratory test parameters associated with citalopram treatment.

ECG changes.

Electrocardiograms from citalopram (n = 802) and placebo (n = 241) groups were compared with respect to outliers defined as subjects with QTc changes over 60 msec from baseline or absolute values over 500 msec postdose, and subjects with heart rate increases to over 100 bpm or decreases to less than 50 bpm with a 25% change from baseline (tachycardic or bradycardic outliers respectively). In the citalopram group 1.9% of the patients had a change from baseline in QTcF > 60 msec compared to 1.2% of the patients in the placebo group. None of the patients in the placebo group had a postdose QTcF > 500 msec compared to 0.5% of the patients in the citalopram group. The incidence of tachycardic outliers was 0.5% in the citalopram group and 0.4% in the placebo group. The incidence of bradycardic outliers was 0.9% in the citalopram group and 0.4% in the placebo group.
In a thorough QT study, citalopram was found to be associated with a dose dependent increase in the QTc interval (see Section 4.4 Special Warnings and Precautions for Use, QT prolongation and torsade de pointes).

Other events observed during the premarketing evaluation of citalopram.

Following is a list of WHO terms that reflect treatment emergent adverse events, as defined in the introduction (see Section 4.8 Adverse Effects (Undesirable Effects)), reported by patients treated with citalopram at multiple doses in a range of 10 to 80 mg/day during any phase of a trial within the premarketing database of 4,422 patients. All reported events are included except those already listed in Table 1 or elsewhere (see Section 4.8 Adverse Effects (Undesirable Effects)), those events for which a drug cause was remote, those event terms which were so general as to be uninformative, and those occurring in only one patient. It is important to emphasise that, although the events reported occurred during treatment with citalopram, they were not necessarily caused by it.
Events are further categorised by body system and listed in order of decreasing frequency according to the following definitions: very common adverse events are those occurring on one or more occasions in at least 1/10 patients; common adverse events are those occurring in less than 1/10 but at least 1/100; uncommon adverse events are those occurring in less than 1/100 patients but at least 1/1,000 patients; rare events are those occurring in fewer than 1/1,000 patients; unknown cannot be estimated from available data.

Other events observed during the postmarketing evaluation of citalopram.

Although no causal relationship to citalopram treatment has been found, the following adverse events have been reported to be temporally associated with citalopram treatment in at least 3 patients (unless otherwise noted) and not described elsewhere (see Section 4.8 Adverse Effects (Undesirable Effects)): choreoathetosis, epidermal necrolysis (3 cases), erythema multiforme, hepatic necrosis (2 cases), cholestatic hepatitis, hyponatraemia, neuroleptic malignant syndrome, mania, pancreatitis, serotonin syndrome, spontaneous abortion, thrombocytopenia, ventricular arrhythmia, priapism, abnormal dreams, insomnia, confusional state and withdrawal syndrome, disturbance in attention, inappropriate ADH secretion, appetite decreased, abnormal orgasm female, syncope and grand mal convulsion.
Akathisia has been reported very rarely (< 1/10,000).
Cases of QT prolongation have been reported during the postmarketing period, predominantly in patients with pre-existing cardiac disease.

Class effect.

Epidemiological studies, mainly conducted in patients 50 years of age and older, show an increased risk of bone fractures in patients receiving SSRIs and TCAs. The mechanism leading to this risk is unknown. Postpartum haemorrhage has been reported for the therapeutic class of SSRIs/SNRIs (see Section 4.4 Special Warnings and Precautions For Use; Section 4.6 Fertility, Pregnancy and Lactation).

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at www.tga.gov.au/reporting-problems.

4.9 Overdose

In general, the main therapy for all overdoses is supportive and symptomatic care.
Citalopram is given to depressed patients who are at potential risk of suicide. Some reports of attempted suicide with citalopram treated patients have been received. Detail is often lacking regarding precise dose or combination with other drugs and/or alcohol.

Toxicity.

Comprehensive clinical data on citalopram overdose are limited and many cases involve concomitant overdoses of other drugs/alcohol. Fatal cases of citalopram overdose have been reported with citalopram alone; however, the majority of fatal cases have involved overdose with concomitant medications.

Symptoms.

The following symptoms have been seen in reported overdose of citalopram: convulsion, tachycardia, somnolence, QT prolongation, coma, vomiting, tremor, hypotension, cardiac arrest, nausea, serotonin syndrome, agitation, bradycardia, dizziness, bundle branch block, QRS prolongation, hypertension, mydriasis, stupor, sweating, cyanosis, hyperventilation, atrial and nodal rhythm, ventricular arrhythmia, and very rare cases of torsades de pointes.

Treatment.

There is no specific antidote. Treatment is symptomatic and supportive. The use of activated charcoal should be considered. Activated charcoal may reduce absorption of the drug if given within one or two hours after ingestion. In patients who are not fully conscious or have impaired gag reflex, consideration should be given to administering activated charcoal via a nasogastric tube, once the airway is protected. Medical surveillance is advisable. ECG monitoring is recommended when more than 600 mg have been ingested. Convulsions may be treated with diazepam.
ECG monitoring is advisable in case of overdose.
Elimination half-life (t1/2β) and Tmax are independent of the dose taken. Information on these pharmacokinetic parameters can be found (see Section 5.2 Pharmacokinetic Properties).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Biochemical and behavioural studies have shown that citalopram is a potent inhibitor of 5-hydroxytryptamine (5HT, serotonin) uptake. Tolerance to the inhibition of 5HT uptake is not induced by long-term treatment with citalopram.
In vitro studies indicate that citalopram is one of the most selective serotonin reuptake inhibitors (SSRIs) yet developed, with little or no effect on the uptake of noradrenaline (NA), dopamine (DA) and gamma aminobutyric acid (GABA). In comparison with other SSRIs, the decreasing order of selectivity is escitalopram, citalopram, sertraline, paroxetine, fluvoxamine and fluoxetine. The clinical relevance of this in vitro finding has not been established.
In contrast to many tricyclic antidepressants, and some of the newer SSRIs, citalopram has no or very low affinity for a series of receptors including 5HT1A, 5HT2, DA D1 and DA D2 receptors, α1, α2 and β-adrenoceptors, histamine H1, muscarine cholinergic, benzodiazepine and opioid receptors. A series of functional in vitro tests in isolated organs as well as functional in vivo tests have confirmed the lack of receptor affinity.
Suppression of rapid eye movement (REM) sleep is considered a predictor of antidepressant activity. Like tricyclic antidepressants, other SSRIs and MAO Inhibitors, citalopram suppresses REM sleep and increases deep slow wave sleep (based upon a five week single blind study in 16 depressed patients given doses up to 40 mg daily).
Although citalopram does not bind to opioid receptors it potentiates the antinociceptive effect of commonly used opioid analgesics in rats. The clinical significance of this finding has not been established.
The main metabolites of citalopram are all also SSRIs, although their potency and selectivity ratios are lower than those of citalopram, but higher than those of many of the newer SSRIs. The metabolites do not contribute to the overall antidepressant effect.
In humans, citalopram does not impair cognitive function or psychomotor performance to the same extent as amitriptyline and it has slight sedative properties. There were results suggestive of impairment in some tests (critical flicker fusion, coding skills, body sway, immediate memory recall).
Citalopram did not reduce saliva flow in a single dose study in human volunteers and in none of the studies in healthy volunteers did citalopram have significant influence on cardiovascular parameters. Citalopram has no effect on the serum levels of prolactin and growth hormone. Like other SSRIs, citalopram increases plasma prolactin, an effect secondary to the prolactin stimulating role of serotonin.

Clinical trials.

Citalopram in the dose range 20 to 80 mg/day is more effective than placebo in the treatment of depression in the majority of trials, including relapse prevention trials. In the double blind, placebo controlled trials a total of 1,083 patients received citalopram and 486 received placebo. There were three fixed dose trials of 6 weeks duration. In one trial a total of 650 patients with major depression were randomly allocated in approximately equal groups (approx. 130 per group) to receive placebo or 10 mg, 20 mg, 40 mg or 60 mg citalopram. In the other two fixed dose studies, placebo was compared with 20 mg or 40 mg citalopram. Between 88 and 97 patients were treated in each group in one trial and approximately 48 in each group in the other. The remaining 5 trials of 4 or 6 weeks duration used flexible doses in the range of 20 to 80 mg/day.
In two relapse prevention, or maintenance, studies of 24 weeks duration, 257 patients were treated with citalopram and 116 with placebo. In one study, 147 citalopram treated patients who were responders (Montgomery-Asbury Depression Rating Scale, MADRS ≤ 12) in two six week fixed dose studies were re-randomised to receive placebo (N = 42) or continue their previous treatment with 20 mg (N = 48) or 40 mg citalopram (N = 57). In the other study MADRS responders (score ≤ 12) continued from an open 8 week trial and were randomised to receive placebo (N = 74) or continue with their optimal dose of citalopram (range 20 to 60 mg daily, N = 152). In both studies citalopram, independent of dose, reduced relapse rates and prolonged time to relapse compared to placebo.
The majority of the patients in the placebo controlled trials received 40 mg/day. The minimal effective dose was 20 mg/day. Analyses of subgroups of patients showed that patients experiencing their first episode of depression or with less severe depression responded well to the minimal effective dose of 20 mg while patients suffering from severe or recurrent depression achieved better results with 40 or 60 mg/day.
Citalopram demonstrates an equivalent therapeutic efficacy to tricyclic and tetracyclic antidepressants and other SSRIs in the treatment of major depression. The active comparator studies were chiefly randomised double blind studies. In the trials versus tri and tetracyclic antidepressants (TTCA), a total of 682 patients received citalopram and 389 TTCAs. In the comparative trials versus other SSRIs, there were 439 citalopram treated patients and 451 treated with other SSRIs. In the 6 week comparison to imipramine, 20 to 30 mg (N = 187) and 40 to 60 mg (N = 193) citalopram were equally effective as imipramine 100 to 150 mg (N = 92). In an 8 week comparison carried out in hospital settings with fixed doses, 40 mg citalopram (N = 158) was equally effective as 20 mg fluoxetine (N = 158). Likewise in a general practice study, 20 mg citalopram (N = 173) was equally effective to 20 mg fluoxetine (N = 184). A 6 week comparison to fluvoxamine in flexible doses (citalopram 20 to 40 mg (N = 108)/fluvoxamine 100 to 200 mg (N = 109)) also demonstrated equal efficacy.

5.2 Pharmacokinetic Properties

Absorption.

Oral bioavailability is about 80% and independent of food intake (Tmax mean 3.8 hours). The bioavailability of each enantiomer has not been studied separately, but the pharmacokinetics of each enantiomer is different.

Distribution.

The apparent volume of distribution (Vd)β is about 12 to 17 L/kg. The plasma protein binding is below 80% for citalopram and its main metabolites. After six weeks on 40 to 60 mg/day in 10 patients, the mean serum concentration of S-(+)-citalopram was about 50% of the R-(-)-citalopram concentration and the mean serum concentration of R-(-)-DCIT was 1.5 times that of S-(+)-DCIT.

Metabolism.

Citalopram is metabolised to the active N-desmethylcitalopram (DCIT), didemethylcitalopram, citalopram-N-oxide and an inactive deaminated propionic acid derivative. All the active metabolites are also SSRIs, although weaker than the parent compound. Unchanged citalopram is the predominant compound in plasma.

Excretion.

The elimination half-life (t1/2β) is about 1.5 days, and the systemic citalopram plasma clearance (Cls) is about 0.3 to 0.4 L/min, and total (oral) plasma clearance (Cloral) is about 0.4 L/min.
About 12 to 23% of the daily dose is excreted unchanged in the urine. Hepatic (residual) clearance is about 0.3 L/min and renal clearance about 0.05 to 0.08 L/min.
The kinetics are linear. Steady-state plasma levels are achieved in 1 to 2 weeks. Average concentrations of 250 nanomol/L (100 to 500 nanomol/L) are achieved at a daily dose of 40 mg. There is no clear relationship between citalopram plasma levels and therapeutic response or side effects in a study of 650 patients.

5.3 Preclinical Safety Data

High doses of citalopram, which resulted in high plasma concentrations of citalopram and metabolites, have been associated with convulsions and ECG abnormalities in experimental animals.

Genotoxicity.

In assays of genotoxic activity, citalopram showed no evidence of mutagenic or clastogenic activity.

Carcinogenicity.

Citalopram did not show any carcinogenic activity in long-term oral studies using mice and rats at doses up to 240 and 80 mg/kg/day, respectively.
