Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Cortiment.

What is in this leaflet

This leaflet answers some common questions about CORTIMENT. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking CORTIMENT against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What CORTIMENT is used for

CORTIMENT tablets are indicated in adults for induction of remission in patients with mild to moderate active ulcerative colitis (UC) where 5-ASA treatment is not sufficient or not tolerated.

CORTIMENT contains the active ingredient, budesonide. Budesonide belongs to a group of medicines called corticosteroids, which are used to help reduce inflammation.

CORTIMENT is used to treat inflammation of the large intestine (colon), which is an area commonly affected in UC. The tablets are designed to release the active ingredient, budesonide in a controlled manner along the colon.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

CORTIMENT is available only with a doctor's prescription.

There is not enough information to recommend the use of this medicine for patients under the age of 18 years.

Before you take CORTIMENT

When you must not take it

Do not take CORTIMENT if you have an allergy to:

  • any medicine containing budesonide
  • any of the ingredients listed at the end of this leaflet
  • peanut oil.

Some of the symptoms of an allergic reaction may include:

  • rash, itching or hives on the skin
  • shortness of breath, wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body.

Do not take CORTIMENT if you are allergic to peanut oil or soy. CORTIMENT contains lecithin (of Soya origin).

Do not give CORTIMENT to children. CORTIMENT is intended for use by adult patients (older than 18 years). They are not recommended for children.

Do not take CORTIMENT after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. The expiry date refers to the last day of that month.

If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start taking this medicine, talk to your doctor.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you have or have had any of the following medical conditions:

  • infection (including viral, bacterial and/or fungal infections)
  • tuberculosis
  • high blood pressure
  • diabetes
  • osteoporosis
  • stomach ulcer
  • elevated eyeball pressure (glaucoma) or cataract
  • family history of diabetes or glaucoma
  • liver problems
  • mental health problems such as depression
  • scheduled to undergo surgery or are experiencing any other stresses.

Tell your doctor if you have NOT had chicken pox or measles or if you have been in contact with people with chicken pox or measles. These infections may be more serious if you get them while taking CORTIMENT. Your doctor may want to vaccinate you for them before you start on CORTIMENT.

Tell your doctor or pharmacist if you are pregnant or plan to become pregnant or are breast-feeding. Your doctor or pharmacist can discuss with you the risks and benefits involved.

If you have not told your doctor about any of the above, tell him/her before you start taking CORTIMENT.

Taking other medicines

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

CORTIMENT and some medicines may interfere with each other. These include:

  • other corticosteroid medicines such as prednisolone, dexamethasone or cortisone
  • cholesterol-lowering medicines, antacids or medicines used to treat itch caused by liver problems (e.g. cholestyramine)
  • medicines used to treat fungal infections (e.g. ketoconazole or itraconazole)
  • some medicines that contain oestrogens, such as oral contraceptives or hormone replacement therapies
  • medicines used to treat heart failure (e.g. cardiac glycosides such as digoxin)
  • medicines used to treat high blood pressure and fluid build-up (e.g. diuretics)
  • medicine used to treat HIV infections (e.g. HIV protease inhibitors)
  • medicine used to treat epilepsy (e.g. carbamazepine).

These medicines may be affected by CORTIMENT 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 and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

How to take CORTIMENT

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

How much to take

Adults:
Take one CORTIMENT 9 mg tablet in the morning with or without food.

How to take it

Swallow the tablet whole with a glass of water. Do not chew, crush or break the tablets.

When to take it

Take your medicine in the morning 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 remember when to take it.

It does not matter if you take this medicine before or after food.

How long to take it

Continue taking your medicine for as long as your doctor tells you, even if you start feeling better.

Usually you will use this medicine daily for a maximum of eight weeks.

If you forget to take it

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

Otherwise, take the missed dose as soon as you remember, and then go back to taking your medicine as you would normally.

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

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much CORTIMENT. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

While you are taking CORTIMENT

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking CORTIMENT.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine. It may affect other medicines used during surgery.

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

If you are about to have any blood tests, tell your doctor that you are taking this medicine. It may interfere with the results of some tests.

Keep all of your doctor's appointments so that your progress can be checked. Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.

Things you must not do

Do not eat grapefruit or drink grapefruit juice while you are taking CORTIMENT. Grapefruit juice, but no other fruit juices, can affect budesonide levels in the body. This may increase the chances of getting unwanted side effects.

Do not stop taking CORTIMENT without discussing it with your doctor first.

If you suddenly stop taking your medicine, you may become ill.

Do not use it to treat any other complaints unless your doctor tells you to.

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

Things to be careful of

Be careful driving or operating machinery until you know how CORTIMENT affects you. It is unlikely that CORTIMENT will affect your ability to drive and use machines. Care is required because this type of medicine may sometimes cause dizziness or fatigue.

Side effects

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

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Do not be alarmed by the following lists of side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

If you have an allergic reaction, contact your doctor immediately. Signs may include hives or swelling of the face, lips, mouth, tongue and throat. This can make it difficult to breathe.

Tell your doctor or pharmacist if you notice any of the following and they worry you:

  • reflux or heartburn
  • muscle pain, muscle cramps
  • stomach pain
  • dizziness
  • fast or irregular heart beats
  • blurred vision
  • skin rash or itchiness
  • heavy or irregular menstruation in women
  • muscle weakness or fatigue, thirst or a tingling sensation
  • dry mouth
  • Cushing-like symptoms such as round face, acne, weight gain and a tendency to bruise easily
  • nausea (feeling sick) or headache
  • high temperature, sore throat,runny nose, cough and chills
  • reduced response to infection
  • change in behaviour such asnervousness, trouble sleeping, mood swings or depression.

The above list includes the more common side effects of your medicine. They are usually mild and short-lived.

Tell your doctor as soon as possible if you notice any of the following:

  • sleepiness or drowsiness
  • bloating, stomach pain or discomfort
  • indigestion
  • pain in the your limbs
  • swelling in your legs
  • tremor.

The above list includes serious side effects that may require medical attention. Serious side effects are rare.

If any of the following happen, tell your doctor immediately or go to Accident and Emergency at your nearest hospital:

  • a sudden serious allergic reaction (called anaphylaxis) which can lead to breathing difficulties
  • fatigue
  • swelling of the hands, ankles or feet.

The above list includes very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are very rare.

Medicines like CORTIMENT tablets (corticosteroids) may affect the normal production of steroid hormones in your body. The effects include:

  • increased bone fragility (osteoporosis)
  • glaucoma (high eyeball pressure)
  • effect on the adrenal gland (small gland near the kidney).

Psychological problems may develop when taking steroids like CORTIMENT. Discuss it with your doctor if you have experienced symptoms of psychological problems while on CORTIMENT. This is particularly important if you are depressed and may be thinking about committing suicide. In very rare cases, psychological problems have developed when high doses of corticosteroids were taken for a long time.

Your doctor may also tell you to take additional oral corticosteroids during periods of stress such as trauma and surgery.

Tell your doctor or pharmacist if you notice anything else that is making you feel unwell. Other side effects not listed above may occur in some patients.

After taking CORTIMENT

Storage

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

Keep your tablets in a cool dry place where the temperature stays below 30°C.

Do not store CORTIMENT or any other medicine in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.

Keep it where children cannot see or reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Disposal

If your doctor tells you to stop taking this medicine or the expiry date has passed, ask your pharmacist what to do with any medicine that is left over.

4 Clinical Particulars

4.1 Therapeutic Indications

Cortiment prolonged release tablets are indicated in adults for induction of remission in patients with mild to moderate active ulcerative colitis (UC) where 5-ASA treatment is not sufficient or not tolerated.

4.2 Dose and Method of Administration

Dosage.

Adults.

The recommended daily dose for induction of remission is one 9 mg tablet in the morning, for up to 8 weeks.

Paediatric population.

The safety and efficacy of Cortiment prolonged release tablets in children aged 0-18 years has not yet been established. No data are available, therefore the use in paediatric population is not recommended until further data become available.

Elderly.

No special dose adjustment is recommended. However, experience of the use of Cortiment prolonged release tablets in the elderly is limited.

Hepatic and renal impairment population.

Cortiment was not studied in patients with hepatic and renal impairment, therefore caution should be exercised in the administration and monitoring of the product in these patients.

Method of administration.

One tablet of Cortiment is taken orally in the morning, with or without food. The tablet should be swallowed with a glass of water and must not be broken, crushed or chewed as the film coating is intended to ensure a prolonged release.

4.3 Contraindications

Hypersensitivity to the active substance, to peanut oil or to any of the excipients listed, see Section 2 Qualitative and Quantitative Composition.
Cortiment prolonged release tablets contain lactose monohydrate and lecithin (of Soya origin).

4.4 Special Warnings and Precautions for Use

Use Cortiment prolonged release tablets with caution in patients with infections, hypertension, diabetes mellitus, osteoporosis, peptic ulcer, glaucoma or cataracts or with a family history of diabetes or glaucoma or with any other condition where the use of glucocorticoids may have unwanted effects.

Hypercorticism and HPA axis suppression.

Glucocorticoids may cause suppression of the HPA axis and reduce the stress response. Where patients are subject to surgery or other stresses, supplementary systemic glucocorticoid treatment is recommended. Since Cortiment prolonged release tablet is a glucocorticosteroid, general warnings concerning glucocorticoids should be followed. Systemic effects of steroids may occur, particularly when prescribed at high doses and for prolonged periods. Such effects may include Cushing's syndrome, adrenal suppression, growth retardation, decreased bone mineral density, cataract, glaucoma and very rarely a wide range of psychiatric/ behavioural effects (see Section 4.8 Adverse Effects (Undesirable Effects)).

Transfer from other steroid therapy.

Treatment with Cortiment prolonged release tablets results in lower systemic steroid levels than conventional oral glucocorticoid therapy. Transfer from other steroid therapy may result in symptoms relating to the change in systemic steroid levels. Signs of adrenocortical suppression has been observed when patients are transferred from systemic corticosteroid treatment with higher systemic effect. Some patients may feel unwell in a nonspecific way during the withdrawal phase, e.g. pain in muscles and joints. Replacement of systemic glucocorticoids with low bioavailability formulations such as Cortiment prolonged release tablets may unmask allergies such as rhinitis and eczema that were previously controlled by the systemic drug. Other symptoms associated with steroid withdrawal, such as benign intracranial hypertension may develop. Therefore monitoring of adrenocortical function may be considered in these patients and their dose of systemic steroid should be reduced with caution.
A general insufficient corticosteroid effect should be suspected if, in rare cases, symptoms such as tiredness, headache, nausea and vomiting should occur. In these cases a temporary increase in the dose of systemic corticosteroids is sometimes necessary.

Immunosuppression and infections.

Suppression of the inflammatory response and immune system increases the susceptibility to infections and their severity. The clinical presentation can be atypical and serious infections such as sepsis and tuberculosis may be masked and may reach an advanced stage before being recognised. Chicken pox and measles may follow a more serious course in patients on oral glucocorticoids. Particular care should be taken to avoid exposure in patients who have not previously had these diseases. If patients are exposed consider reduction or discontinuation of glucocorticoid treatment at the discretion of the treating physician. Therapy with varicella zoster immunoglobulin (VZIG) or pooled intravenous immunoglobulin (IVIG), as appropriate, may be needed. If a diagnosis of chicken pox is confirmed, the illness warrants specialist care and urgent treatment. Patients with compromised immunity who have come into contact with measles should, wherever possible, receive IVIG as soon as possible after exposure.
Glucocorticosteroids should be used with caution, if at all, in patients with active or quiescent tuberculosis infection, untreated fungal, bacterial, systemic viral or parasitic infections.
Coadministration of Cortiment prolonged release tablets is likely to reduce the immune response to vaccines.

Increased systemic glucocorticoid susceptibility.

Impaired liver function may affect the elimination of glucocorticoids, and increased systemic availability of oral budesonide has been evidenced in patients with moderately severe hepatic cirrhosis. The risk of systemic adverse effects is increased in patients with severe liver impairment (e.g. liver cirrhosis).
In vivo studies have shown that oral administration of ketoconazole (a known inhibitor of CYP3A activity in the liver and in the intestinal mucosa), caused a several fold increase of the systemic exposure to oral budesonide. If treatment with ketoconazole together with budesonide is indicated, discontinuation of the budesonide treatment should be considered if side effects typical of systemic glucocorticoids occur. Following significant intake of grapefruit juice (which inhibits CYP3A activity predominantly in the intestinal mucosa), the systemic exposure to oral budesonide increased by approximately twofold. As with other drugs primarily being metabolised by CYP3A, regular ingestion of grapefruit or grapefruit juice simultaneously with budesonide administration should be avoided (other juices such as orange juice or apple juice do not inhibit CYP3A activity) (see Section 4.5 Interactions with Other Medicines and Other Forms of Interactions).

Gastrointestinal tolerance.

Cortiment prolonged release tablets contain lactose monohydrate and should not be taken by patients with rare hereditary problems such as galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption.
A 28 day oral repeat dose study in cynomolgous monkeys at doses up to 18 mg/day (at least 25 times the maximal recommended daily dose in humans) reported no significant adverse effects on the gastrointestinal tract.

Other glucocorticosteroid effects.

Affective disorders.

Particular care is required when considering the use of systemic corticosteroids in patients with current or previous history of severe affective disorders in the patient or any first degree relatives.

Visual disturbance.

Visual disturbance may be reported with systemic and topical corticosteroid use. If a patient presents with symptoms such as blurred vision or other visual disturbances, the patient should be considered for referral to an ophthalmologist for evaluation of possible causes which may include cataract, glaucoma or rare diseases such as central serous chorioretinopathy (CSCR) which have been reported after use of systemic and topical corticosteroids.
Cortiment prolonged release tablets contain lactose monohydrate and should not be taken by patients with rare hereditary problems such as galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption.

Use in hepatic and renal impairment.

Cortiment prolonged-release tablets were not studied in patients with hepatic and renal impairment; therefore, caution should be exercised in the administration and monitoring of the product in these patients (see Section 4.4 Special Warnings and Precautions for Use, Increased systemic glucocorticoid susceptibility).

Use in the elderly.

No special dose adjustment is recommended. However, experience of the use of Cortiment prolonged release tablets in the elderly is limited.

Paediatric use.

Safety and efficacy of Cortiment prolonged release tablets in children aged 0-18 years have not yet been established. No data are available; therefore, the use in paediatric population is not recommended until further data become available.

Effects on laboratory tests.

Because adrenal and/or pituitary function may be suppressed, an ACTH stimulation test for diagnosing pituitary or adrenal insufficiency might show false results (low values of cortisol).

4.5 Interactions with Other Medicines and Other Forms of Interactions

No interaction studies have been performed with Cortiment.
Budesonide has a lower systemic bioavailability compared to other glucocorticoids, so drug-drug interactions may be reduced compared to many glucocorticoids. Patients with an increased risk of drug interactions include the elderly and those with impaired renal or hepatic function.
Budesonide is primarily metabolised by cytochrome P450 3A4 (CYP3A4). Inhibitors of this enzyme, e.g. ketoconazole, itraconazole, HIV protease inhibitors (including cobicistat-containing products) and grapefruit juice, can therefore increase systemic exposure to budesonide several times and the risk of systemic side effects (see Section 4.4 Special Warnings and Precautions for Use; Section 5 Pharmacological Properties). The combination should be avoided unless the benefit outweighs the increased risk of systemic corticosteroid side-effects, in which case patients should be monitored for systemic corticosteroid side-effects. If treatments are combined, the period between dosing of the combined treatments should be as long as possible and a reduction of the budesonide dose could also be considered. Budesonide is unlikely to inhibit other drugs metabolised via CYP3A4, since budesonide has low affinity to the enzyme.
Concomitant treatment with CYP3A4 inducers such as carbamazepine may reduce budesonide exposure, which may require a dose increase.
Corticosteroid interactions that may present a significant hazard to selected patients are those with cardiac glycosides (increased effect due to reduced potassium levels) and diuretics (increased elimination of potassium).
Increased plasma concentrations of and enhanced effects of corticosteroids have been observed in women also treated with oestrogens and contraceptive steroids, but no such significant effect has been observed with budesonide and concomitant intake of low dose combination oral contraceptives.
Although not studied, concomitant administration of cholestyramine or antacids may reduce budesonide uptake, in common with other drugs. Therefore, these preparations should not be taken simultaneously, but at least two hours apart.
At recommended doses, omeprazole does not affect the pharmacokinetics of oral budesonide, whereas cimetidine has a slight but clinically insignificant effect.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

There are no data on the effect of Cortiment on human fertility. Subcutaneous administration of budesonide to rats at doses up to 20 microgram/kg/day did not affect fertility.
(Category B)
In animal studies, budesonide was found to cross the placental barrier. In pregnant rats and rabbits, administration of budesonide, like other glucocorticosteroids, has been shown to cause fetal death, fetal adrenal suppression, and abnormalities of fetal development (reductions in fetal/ pup growth and litter size, and skeletal and visceral abnormalities). Some glucocorticoids have been reported to produce cleft palate in animals. The relevance of these findings to humans has not been established, and there are limited data on pregnancy outcomes after oral administration of budesonide.
However, as with other drugs the administration of Cortiment prolonged release tablets during pregnancy requires that the benefits for the mother are weighed against the risks for the fetus. Cortiment prolonged release tablets should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus.
Budesonide is excreted in breast milk.
Maintenance treatment with inhaled budesonide (200 or 400 microgram twice daily) in asthmatic nursing women results in negligible systemic exposure to budesonide in breast-fed infants.
In a pharmacokinetic study the estimated daily infant dose was 0.3% of the daily maternal dose for both dose levels, and the average plasma concentration in infants was estimated to be 1/600th of the concentrations observed in maternal plasma, assuming complete infant oral bioavailability.
Budesonide concentrations in infant plasma samples were all less than the limit of quantification. Based on data from inhaled budesonide and the fact that budesonide exhibits linear PK properties within the therapeutic dosage intervals after inhaled, oral and rectal administrations, at therapeutic doses of budesonide, exposure to the suckling child is anticipated to be low. These data support continued use of budesonide, oral and rectal administrations, during breastfeeding.

4.7 Effects on Ability to Drive and Use Machines

No studies on the effects of Cortiment prolonged release tablets on the ability to drive and use machines have been performed. When driving vehicles or using machines it should be taken into account that occasionally dizziness or tiredness may occur (see Section 4.8 Adverse Effects (Undesirable Effects)).

4.8 Adverse Effects (Undesirable Effects)

In phase II and III clinical trials, the incidences of adverse events for Cortiment prolonged release tablets, at the recommended dose of 9 mg/day, were comparable to placebo. Most adverse events were of mild to moderate intensity and of a nonserious nature. Because clinical trials are conducted under different conditions, the incidences of adverse events in these clinical trials cannot be directly compared to the incidences in other clinical trials of another product and may not reflect the incidences observed in practice.
Adverse drug reactions reported in clinical trials with Cortiment 9 mg prolonged-release tablets are presented in Table 1.
Adverse drug reactions reported for the therapeutic class are presented in Table 2.
Most of the adverse events mentioned can also be expected for other treatments with glucocorticoids.
Side effects typical of systemic glucocorticosteroids (e.g. cushingoid features and growth retardation) may occur. These side effects are dependent on dose, treatment time, concomitant and previous corticosteroid intake, and individual sensitivity.

Paediatric population.

No data available.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after authorisation 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

Due to the low systemic availability of Cortiment prolonged release tablets, acute overdosage even at very high doses is not expected to lead to an acute clinical crisis. In the event of acute overdosage, no specific antidote is available. Treatment consists of supportive and symptomatic therapy.
For information on the management of overdose, contact the Poison Information Centre on 131126 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Pharmacotherapeutic group: intestinal anti-inflammatory agents, corticosteroids acting locally. ATC code: A07EA06.
Budesonide is a glucocorticoid used in the treatment of inflammatory bowel disease. It does not reduce cortisol levels to the same extent as prednisolone. Its affinity for glucocorticoid receptors is approximately 200 times greater than that of hydrocortisone, and about 15 times that of prednisolone.
Cortiment contains budesonide in an extended release tablet core covered by a coating that dissolves in intestinal fluids having a pH greater than 7. Budesonide is then released into the intestinal tract throughout the colon.
When the protective layer is lost, intestinal fluid then comes into contact with the hydrophilic matrix polymers, which start to swell until a viscous gel matrix is formed. The solvent that penetrates into the gel matrix dissolves the active ingredient from the lipophilic matrices.

Mechanism of action.

The exact mechanism of action of budesonide in the treatment of ulcerative colitis (UC) is not fully understood. In general, budesonide inhibits many inflammatory processes including cytokine production, inflammatory cell activation and expression of adhesion molecules on endothelial and epithelial cells. At doses clinically equivalent to prednisolone, budesonide gives less hypothalamic pituitary adrenal (HPA) axis suppression and has a lower impact on inflammatory markers.
Systemic bioavailability of budesonide is about 10% (see Section 5.2 Pharmacokinetic Properties, Absorption). Data from clinical pharmacology and pharmacokinetic studies for Cortiment prolonged release tablets indicate that about 96% of drug absorption occurs in the colon, supporting the availability of budesonide at the intended site of action.

Clinical trials.

Two similarly designed, randomised, double blind, placebo controlled studies were conducted in adult patients with mild to moderate active UC (defined as an UCDAI of ≥ 4 and ≤ 10). Together, 899 patients with histology consistent with active UC formed the ITT population, of which 232 patients were treated with Cortiment 9 mg and 210 patients were treated with placebo once daily for 8 weeks. Patients were either treatment naïve or had failed on 5-ASA. The primary endpoint was induction of remission after 8 weeks of treatment. Remission was defined as an UCDAI score of ≤ 1, with subscores of 0 for rectal bleeding, stool frequency, and mucosal appearance and with a ≥ 1 point reduction in endoscopy score. In both studies, Cortiment 9 mg showed superiority to placebo in inducing remission (see Table 3).
Statistical difference versus placebo was reached for Cortiment 9 mg for both studies and the difference versus placebo was 10.4% and 12.9% respectively.
5-ASA is the standard of care for treatment of mild to moderate disease. Results of a head to head comparison with Cortiment and 5-ASA are not available. Therefore, the place in the therapeutic work-up remains to be established. Some patients may benefit from treatment initially with Cortiment prolonged release tablets.
Cortiment prolonged release tablets were not studied in the paediatric population.

5.2 Pharmacokinetic Properties

Absorption.

Following single oral administration of Cortiment 9 mg in healthy subjects, maximum plasma concentration (Cmax) of budesonide was 1.35 ± 0.96 nanogram/mL at 13.3 ± 5.9 hours postdose (Tmax), and the area under the plasma concentration time curve (AUC) was approximately 13.56 ± 7.82 nanogram.hr/mL. The systemic bioavailability of budesonide is about 10%, due to extensive first pass metabolism in the liver. Concomitant administration of Cortiment with food had minimal clinically relevant effect on systemic exposure to budesonide. There was no evidence for accumulation of systemic exposure to budesonide following 7 daily doses of Cortiment 9 mg.

Distribution.

Budesonide has a high volume of distribution (about 3 L/kg). Plasma protein binding averages 85-90%.

Metabolism.

Budesonide undergoes extensive biotransformation in the liver to metabolites of low glucocorticoid activity. The glucocorticoid activity of the major metabolites, 6β-hydroxybudesonide and 16α-hydroxy-prednisolone, is less than 1% of that of budesonide. The metabolism of budesonide is primarily mediated by CYP3A, a subfamily of cytochrome P450.

Excretion.

Elimination of budesonide is rate limited by absorption. Budesonide has a high systemic clearance (about 1.2 L/min).

5.3 Preclinical Safety Data

Carcinogenicity.

The carcinogenic potential of budesonide has been assessed in mice and rats at respective oral doses up to 200 and 50 microgram/kg/day. No oncogenic effect was noted in mice. One study showed an increased incidence of malignant gliomas in male Sprague-Dawley rats given budesonide 50 microgram/kg/day; however this was not confirmed in further studies in male Sprague-Dawley and Fischer rats. In male rats dosed with 10, 25 and 50 microgram/kg/day, those receiving 25 and 50 microgram/kg/day showed an increased incidence of primary hepatocellular tumours; however this was also observed in rats treated with prednisolone and triamcinolone acetonide, thus indicating a class effect of corticosteroids in rats.

Genotoxicity.

Budesonide had no mutagenic effects in a number of in vitro and in vivo tests.
