1. Why am I taking APO-Lansoprazole ODT?

APO-Lansoprazole ODT contains the active ingredient lansoprazole.

APO-Lansoprazole ODT is a type of medicine called a proton pump inhibitor (PPI). It works by reducing the amount of acid the stomach makes, to give relief from the symptoms of excessive acid and allow healing to take place. This does not stop food being digested in the normal way.

APO-Lansoprazole ODT is taken for:

Peptic Ulcers

APO-Lansoprazole ODT is used to treat peptic ulcers (also called gastric or duodenal ulcers) in adults.

Too much acid being made in the stomach can cause these ulcers. APO-Lansoprazole ODT is also used to help stop duodenal ulcers from coming back.

Reflux Oesophagitis

APO-Lansoprazole ODT is used to treat reflux oesophagitis or reflux disease in adults and in children from 6 to 17 years of age.

This can be caused by backflow (reflux) of food and acid from the stomach into the food pipe/oesophagus. Reflux can cause a burning sensation in the chest rising up to the throat, also known as heartburn.

Heartburn and stomach pain associated with reflux or peptic ulcer.

APO-Lansoprazole ODT is used for the short-term treatment of heartburn and peptic ulcer symptoms in adults.

Peptic Ulcers Associated with Helicobacter Pylori Infection

Most people who have a peptic ulcer also have a bacteria called Helicobacter pylori in their stomach. APO-Lansoprazole ODT can be taken in conjunction with certain antibiotics to help eradicate Helicobacter pylori and let your peptic ulcer heal.

However, it is possible that the antibiotics may not always get rid of Helicobacter pylori.

2. What should I know before I take APO-Lansoprazole ODT?

Warnings

Do not take APO-Lansoprazole ODT if:

  • you are allergic to lansoprazole, other proton pump inhibitors (PPIs) or any of the ingredients listed at the end of this leaflet. Always check the ingredients to make sure you can take this medicine.
  • you have severe liver disease
  • you are already taking atazanavir, a medicine used to treat HIV infection. If atazanavir is taken at the same time as APO-Lansoprazole ODT, atazanavir will not be absorbed properly and will be less effective in treating HIV infection

Check with your doctor if you:

  • had or have any other medical conditions including:
    - kidney or liver problems
    - inflammation of the bowel
    - a tumour in the stomach area
    - osteoporosis
    - low magnesium levels
    - glucose-galactose malabsorption
    - a rash or skin reaction after treatment with a proton pump inhibitor medicine like APO-Lansoprazole ODT that reduces stomach acid.
  • have problems with digestion, or have an intolerance to:
    - fructose, glucose, galactose, sucrose or maltose
    - lactose
    - aspartame.

During treatment, you may be at risk of developing certain side effects, including fractures if treatment is long-term. 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.

Your doctor will discuss the possible risks and benefits of taking APO-Lansoprazole ODT during pregnancy. Talk to your doctor if you are breastfeeding or intend to breastfeed. Taking APO-Lansoprazole ODT during breastfeeding should be avoided as it is not known if this medicine passes into your breast milk.

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.

Some medicines may interfere with APO-Lansoprazole ODT and affect how it works.

  • theophylline, used to treat asthma.
  • carbamazepine and phenytoin, used to treat seizures (fits).
  • warfarin, used to prevent blood clots.
  • tacrolimus or mycophenolate, immune suppressants used in transplant patients to reduce organ rejection.
  • fluvoxamine, used to treat depression and other mental health conditions.
  • oral contraceptives (birth control pills).
  • ampicillin esters, used in some antibiotics.
  • ketoconazole, used to treat fungal infections.
  • iron preparations.
  • digoxin, used to treat heart conditions.
  • methotrexate, used in rheumatoid arthritis, psoriasis and certain cancers.
  • atazanavir, nelfinavir and other HIV medicines.
  • sucralfate (used to treat stomach ulcers) and antacids (used to treat heartburn and indigestion).

APO-Lansoprazole ODT should be taken at least an hour before taking sucralfate or antacids.

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

4. How do I take APO-Lansoprazole ODT?

How much to take

Your doctor or pharmacist will tell you how much to take and for how long to take APO-Lansoprazole ODT as it depends on the condition you are taking it for.

Adults

The usual dose for adults is 30 mg once daily. The dose may vary from 15 mg daily to 30 mg twice daily depending on the condition being treated.

Children

6 to 11 years old

The recommended dose for this age group depends on the weight of the child.

For children weighing 30 kg or less, the usual dose is 15 mg once daily.

For children weighing over 30 kg, the usual dose is 30 mg once daily.

12 to 17 years old

The usual dose may vary from 15 mg to 30 mg once daily depending on the condition being treated.

When to take APO-Lansoprazole ODT

APO-Lansoprazole ODT should be taken in the morning before food.

APO-Lansoprazole ODT works best when taken on an empty stomach.

How to take APO-Lansoprazole ODT

There are two ways you can take:

Swallow the tablet whole with a glass of water, or gently suck the tablet, then swallow the granules with your saliva.

Do not chew or crush the tablet as this affects how well APO-Lansoprazole ODT works.

How long to take APO-Lansoprazole ODT

Keep taking APO-Lansoprazole ODT as directed, unless your doctor gives you other instructions.

In most patients, APO-Lansoprazole ODT relieves symptoms rapidly and healing is usually complete within 4 weeks. In some patients a further 4 weeks of treatment may be needed for complete healing.

In some cases, your doctor may decide that long term treatment is needed.

Tell your doctor if any of your symptoms return after stopping long term treatment.

APO-Lansoprazole ODT is recommended only for short term use (8 to 12 weeks) in children.

For children aged 6 to 11 years, do not exceed 12 weeks of treatment with APO-Lansoprazole ODT.

For children aged 12 to 17 years, do not exceed 8 weeks of treatment with APO-Lansoprazole ODT.

Tell your doctor if your symptoms return.

You may need further treatment.

If you forget to take APO-Lansoprazole ODT

APO-Lansoprazole ODT should be taken regularly at the same time each day. If you miss your dose at the usual time, take it as soon as you remember, and then go back to your normal routine.

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 take too much APO-Lansoprazole ODT

If you think that you have taken too much APO-Lansoprazole ODT, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (by calling 13 11 26), 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 taking APO-Lansoprazole ODT?

Things you should do

Take APO-Lansoprazole ODT exactly as your doctor has prescribed.

If you are about to start any new medicine, remind your doctor and pharmacist that you are taking APO-Lansoprazole ODT.

Tell all doctors, dentists, pharmacists and nurses who are treating 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.

Tell your doctor if you become pregnant while you are taking APO-Lansoprazole ODT.

Discuss the need for any additional supplements (e.g. vitamin D, magnesium, calcium, vitamin B12), with your doctor, especially if taking APO-Lansoprazole ODT long-term.

Immediately alert your doctor if you experience:

  • stomach pain and fever with diarrhoea which may contain blood or mucus
  • red, itchy, blistering spots on skin, or a rash that may include peeling, and may be accompanied by fever, weakness, fatigue or muscle pain.

Things you should not do

  • Do not breastfeed while taking APO-Lansoprazole ODT.
  • Do not give your medicine to anyone else, even if they have the same condition as you.
  • Do not take APO-Lansoprazole ODT to treat any other complaints unless your doctor tells you to.

  • If you stop taking it suddenly, your condition may worsen, or you may have unwanted side effects.

Driving or taking machines

Be careful before you drive or take any machines or tools until you know how APO-Lansoprazole ODT affects you.

APO-Lansoprazole ODT generally does not cause any problems with your ability to drive a car or operate machinery. However, as with many other medicines, APO-Lansoprazole ODT may cause dizziness in some people. Make sure you know how you react to APO-Lansoprazole ODT before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy.

Drinking alcohol

As you may experience dizziness when taking APO-Lansoprazole ODT, drinking alcohol may make the dizziness worse.

Things that may help your condition

Some self-help measures suggested below may help your condition. Talk to your doctor or pharmacist about these measures and for more information.

  • Alcohol

Your doctor may advise you to limit your alcohol intake.

  • Aspirin and many other medicines used to treat arthritis, period pain or headaches

These medicines may irritate the stomach and may make your condition worse. Your doctor or pharmacist may suggest other medicines you can take.

  • Caffeine

Your doctor may advise you to limit the number of drinks that contain caffeine, such as coffee, tea, cocoa and cola drinks, because they contain ingredients that may irritate the stomach.

  • Eating habits

Eat smaller, more frequent meals. Eat slowly and chew your food carefully. Try not to rush at mealtimes. Eat your meals well before bedtime.

  • Smoking

Your doctor may advise you to stop smoking or at least cut down.

  • Weight

Your doctor may suggest losing some weight to help your condition.

Looking after your medicine

  • Keep your tablets in their blister pack until it is time to take them.
  • If you take the tablets out of the blister pack, they may not keep well.
  • Keep it in a cool dry place where the temperature stays below 25°C.

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

Store it in a cool dry place away from moisture, heat or sunlight; for example, do not store it:

Call your doctor straight away or go straight to the Emergency Department at your nearest hospital if you notice any of these serious side effects.

Tell your doctor or pharmacist if you notice anything else that may be making you feel unwell.

Other side effects not listed here may occur in some people.

As natural acid in the stomach helps to kill bacteria, the lowering of acid by acid-reducing medicines such as APO-Lansoprazole ODT may cause some people to get certain stomach infections.

Other problems are more likely to arise from the ulcer itself rather than the treatment.

For this reason, contact your doctor immediately if you notice any of the following:

  • Pain or indigestion occurring during treatment with APO-Lansoprazole ODT.
  • You begin to vomit blood or food.
  • You pass black (blood-stained) motions.

Reporting side effects

After you have received medical advice for any side-effects you experience, you can report side effects to the Therapeutic Goods Administration online at www.tga.gov.au/reporting-problems. By reporting side effects, you can help provide more information on the safety of this medicine.

Always make sure you speak to your doctor or pharmacist before you decide to stop taking any of your medicines.

4 Clinical Particulars

4.1 Therapeutic Indications

Adults.

Healing and long-term management of reflux oesophagitis.
Healing and long-term management for patients with duodenal ulcer.
Healing of benign gastric ulcer. Patients whose gastric or duodenal ulcer is not associated with ingestion of nonsteroidal anti-inflammatory drugs (NSAIDs) require treatment with antimicrobial agents in addition to antisecretory drugs whether on first presentation or on recurrence.
APO-Lansoprazole ODT is also effective in patients with benign peptic lesions that do not respond to H2-receptor antagonists.
Eradication of H. pylori from the upper gastrointestinal tract in patients with peptic ulcer or chronic gastritis when used in combination with appropriate antibiotics (see Section 5.1 Pharmacodynamic Properties, Clinical trials).
Relief of reflux-like and/or ulcer-like symptoms associated with acid related dyspepsia.

Paediatric patients 6 to 17 years of age.

Treatment of gastro-oesophageal reflux disease (GORD), including all grades of oesophagitis.
Healing of erosive oesophagitis.

4.2 Dose and Method of Administration

For oral administration.
APO-Lansoprazole ODT is strawberry flavoured and should be placed on the tongue and gently sucked. The tablet rapidly disperses in the mouth, releasing the enteric coated pellets, which are swallowed with the patient's saliva. Alternatively, the tablet can be swallowed whole with a drink of water. The tablets must not be chewed.
The tablets should not be crushed or chewed (see Section 4.4 Special Warnings and Precautions for Use). To achieve the optimal acid inhibitory effect, and hence most rapid healing and symptom relief, APO-Lansoprazole ODT 'once daily' should be administered in the morning before food.

Adults.

Reflux oesophagitis.

APO-Lansoprazole ODT 30 mg once daily for 4 weeks. The majority of patients will be healed after the first course. For patients who have not fully healed within this time, a further 4 weeks treatment using the same dosage regimen is indicated. For long-term management, a maintenance dose of 15 mg or 30 mg once daily can be used dependent upon patient response.

Duodenal ulcer*.

APO-Lansoprazole ODT 30 mg once daily for 4 weeks. For the prevention of relapse, the recommended maintenance dose is 15 mg once daily.

Gastric ulcer*.

APO-Lansoprazole ODT 30 mg once daily for 8 weeks.
* Patients whose gastric or duodenal ulcer is not associated with ingestion of NSAIDs require treatment with antimicrobial agents in addition to antisecretory drugs whether on first presentation or on recurrence.

Acid related dyspepsia.

APO-Lansoprazole ODT 15 mg or 30 mg once daily for 2-4 weeks, depending on the severity and persistence of symptoms. Patients who do not respond after 4 weeks, or who relapse shortly afterwards, should be investigated.

Eradication of H. pylori.

The following combinations have been shown to be effective when used for 7 days. APO-Lansoprazole ODT 30 mg twice daily plus two of the following antibiotics: amoxicillin 1 g twice daily, metronidazole 400 mg twice daily or clarithromycin 250 mg twice daily.

Paediatrics.

Paediatric patients 6 to 11 years of age.

In clinical studies, lansoprazole was not administered beyond 12 weeks in 6 to 11 years old. It is not known if lansoprazole is safe and effective if used longer than the recommended duration. Do not exceed the recommended dose and duration of use in children as outlined in Table 1 (see Section 5.3 Preclinical Safety Data for nonclinical data).

Paediatric patients 12 to 17 years of age.

In clinical studies, lansoprazole was not administered beyond 8 weeks in 12 to 17 years old. It is not known if lansoprazole is safe and effective if used longer than the recommended duration. Do not exceed the recommended dose and duration of use in children as outlined in Table 2.

4.3 Contraindications

Hypersensitivity to lansoprazole, other proton pump inhibitors (PPIs) or any of the excipients in the tablets.
Severe hepatic impairment.
Lansoprazole should not be coadministered with atazanavir due to a significant reduction in atazanavir exposure.

4.4 Special Warnings and Precautions for Use

As with other antiulcer therapies, the possibilities of malignancy should be excluded when a gastric ulcer is suspected, since treatment with lansoprazole may alleviate the symptoms of a malignancy and possibly delay its diagnosis.
Similarly, the possibility of serious underlying disease such as malignancy should be excluded before treatment for dyspepsia commences, particularly in patients of middle age or older who have new or recently changed dyspeptic symptoms.
The pellets in APO-Lansoprazole ODT are enteric coated. Therefore, the tablets should be sucked slowly and should not be crushed or chewed.

Use with caution in the following circumstances.

Agents that elevate gastric pH may increase the already present risk of nosocomial pneumonia in intubated ICU patients receiving mechanical ventilation.
When using lansoprazole with antibiotics to eradicate H. pylori, it is recommended that prescribers refer to the approved product information for the antibiotics selected.
Decreased gastric acidity due to any means, including proton pump inhibitors, increases gastric counts of bacteria normally present in the gastrointestinal tract. Treatment with acid reducing drugs may lead to a slightly increased risk of gastrointestinal infections such as Salmonella and Campylobacter.
Proton pump inhibitor therapy may be associated with an increased risk of Clostridium difficile infection.
Daily treatment with any acid-suppressing medications over a long period of time (e.g. longer than 3 years) may lead to malabsorption of cyanocobalamin (vitamin B12) caused by hypo- or achlorhydria. Cyanocobalamin deficiency should be considered in patients with Zollinger-Ellison syndrome and other pathological hypersecretory conditions requiring long-term treatment, individuals with reduced body stores or risk factors for reduced vitamin B12 absorption (such as the elderly) on long-term therapy or if relevant clinical symptoms are observed.
PPIs, especially if used in high doses and over long durations (> 1 year), may modestly increase the risk of hip, wrist and spine fracture, predominantly in the elderly or in presence of other recognised risk factors. Observational studies suggest that PPIs may increase the overall risk of fracture. Some of this increase may be due to other risk factors. Patients at risk of osteoporosis should receive clinical guidelines and they should have an adequate intake of vitamin D and calcium.

Enterochromaffin-like (ECL) cell effects.

Safety concerns of long-term treatment relate to hypergastrinaemia and possible ECL effects. ECL cell hyperplasia and gastric carcinoid tumour were observed in animal studies.
Human gastric biopsy specimens from patients treated with proton pump inhibitors have not detected ECL cell effects similar to those seen in rats. Gastric biopsies taken in all the long-term maintenance studies have revealed:
a slight increase in mean endocrine cell count during 12 months maintenance treatment with lansoprazole 15 or 30 mg, observed in 3 of 4 studies. Cell density averages were slightly higher under 30 mg lansoprazole than under 15 mg lansoprazole once daily. These observations were reversible approximately 3 months after maintenance therapy stopped in two of the studies;
single cases of changes from normal to simple hyperplasia which persisted in one patient 3 months after discontinuation of treatment;
for antral biopsies a greater mean gastrin positive cell density and mean serotonin positive cell density was found for lansoprazole 30 mg compared to lansoprazole 15 mg once daily;
no evidence of carcinoid tumours or visible endocrine cell proliferation was seen in any patient for either fundus or antral biopsies.
(There are currently biopsy data on over 400 patients treated between 9 months and one year and over 230 patients treated for more than one year.)

Retinal atrophy.

In animal studies, retinal atrophy was observed in Sprague Dawley rats dosed orally with lansoprazole. Retinal atrophy has not been found in mice, dogs, monkeys or humans. Mechanistic studies have indicated that the effect is specific to species dependent on hepatic synthesis of the amino acid taurine, which has a protective effect on the retina. Lansoprazole inhibits hepatic synthesis of taurine; however, humans obtain their taurine requirements from the diet.

Acute tubulointerstitial nephritis (TIN).

Acute TIN has been observed in patients taking PPIs including lansoprazole. Acute TIN may occur at any point during PPI therapy and is generally attributed to an idiopathic hypersensitivity reaction. Discontinue lansoprazole if acute TIN develops.

Hypomagnesaemia.

Hypomagnesaemia, symptomatic and asymptomatic, has been reported rarely in patients treated with PPIs for at least three months, in most cases after a year of therapy. Serious adverse events include tetany, arrhythmias, and seizures. In most patients, treatment of hypomagnesaemia required magnesium replacement and discontinuation of the PPI.
For patients expected to be on prolonged treatment or who take PPIs with medications such as digoxin or drugs that may cause hypomagnesaemia (e.g. diuretics), health care professionals may consider monitoring magnesium levels prior to initiation of PPI treatment and periodically during PPI treatment.
Hypomagnesaemia may lead to hypocalcaemia and/or hypokalaemia (see Section 4.8 Adverse Effects (Undesirable Effects)).

Severe cutaneous adverse reactions.

Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), acute generalised exanthematous pustulosis (AGEP) and erythema multiforme have been reported in association with the use of PPIs (see Section 4.8 Adverse Effects (Undesirable Effects)). Discontinue lansoprazole at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation.

Subacute cutaneous lupus erythematosus (SCLE).

Proton pump inhibitors are associated in rare cases with the occurrence of subacute cutaneous lupus erythematosus (SCLE). If lesions occur, especially in sun exposed areas of the skin, and if accompanied by arthralgia, the patient should seek medical help promptly and the healthcare professional should consider stopping the product.

Use in hepatic impairment.

Lansoprazole is metabolised substantially by the liver. The results of clinical trials in adult patients with liver disease indicate that the metabolism of lansoprazole is prolonged in patients with severe hepatic impairment. Consider dose adjustment in patients with severe hepatic impairment.

Use in renal impairment.

There is no need to alter the dosage in adult patients with impaired renal function.

Use in the elderly.

Dosage adjustment is not required in the elderly.

Paediatric use.

See Section 4.2 Dose and Method of Administration, Paediatrics.
There is insufficient experience to recommend the use of lansoprazole in paediatric patients with hepatic or renal impairment.

Effects on laboratory tests.

Increased Chromogranin A (CgA) level may interfere with investigations for neuroendocrine tumours. To avoid this interference, proton pump inhibitor treatment should be stopped 14 days before CgA measurements.

4.5 Interactions with Other Medicines and Other Forms of Interactions

Lansoprazole is metabolised in the liver and is a weak inducer of cytochrome P450. Therefore, there is the possibility of interaction with other drugs metabolised via this system, e.g. theophylline, phenytoin, carbamazepine and warfarin. Patients receiving such drugs concomitantly with lansoprazole should be monitored to determine if any dosage adjustment is necessary.
There have been isolated cases of a suspected drug interaction with warfarin, but a definitive relationship to lansoprazole therapy has not been established.
No clinically significant effects on plasma levels of NSAIDs, phenytoin (single IV doses only) and diazepam have been found.
Concomitant administration of lansoprazole and tacrolimus may increase whole blood levels of tacrolimus, especially in transplant patients who are intermediate or poor metabolisers of CYP2C19. Inhibitors of CYP2C19 such as fluvoxamine would likely increase the systemic exposure to lansoprazole. Inducers of CYP2C19 would likely decrease the systemic exposure to lansoprazole.
The possibility of interaction between lansoprazole and low dose oral contraceptives cannot be excluded.
Coadministration of lansoprazole with sucralfate delayed absorption and reduced lansoprazole bioavailability by approximately 30%. Similarly, antacids may also reduce the bioavailability of lansoprazole. Therefore, lansoprazole should be taken at least an hour prior to sucralfate or antacid administration.
Lansoprazole causes a profound and long lasting inhibition of gastric acid secretion; therefore, lansoprazole may interfere with the absorption of drugs where gastric pH is an important determinant of bioavailability (e.g. ketoconazole, ampicillin esters, iron salts, digoxin).
Coadministration of PPIs in healthy subjects and in transplant patients receiving mycophenolate mofetil has been reported to reduce exposure to the active metabolite, mycophenolic acid. This is possibly due to a decrease in mycophenolate mofetil solubility at an increased gastric pH. The clinical relevance of reduced mycophenolic acid exposure on organ rejection has not been established in transplant patients receiving PPIs and mycophenolate mofetil. Use lansoprazole with caution in transplant patients receiving mycophenolate mofetil.
Concomitant use with methotrexate (primarily at high dose), may elevate and prolong serum levels of methotrexate and/or its metabolite, possible leading to methotrexate toxicities. A temporary withdrawal of the PPI may be considered in some patients receiving treatments with high dose methotrexate.
Lansoprazole, and other PPIs, should not be co-administered with HIV protease inhibitors for which absorption is dependent on acidic intragastric pH (e.g. atazanavir and nelfinavir), due to significant reduction in their bioavailability. The decreased systemic concentration of the HIV protease inhibitor may result in a loss of therapeutic effect and the development of HIV resistance.
Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

See Section 5.3 Preclinical Safety Data.
(Category B3)
Reproductive studies conducted in pregnant rats and rabbits at oral doses up to 300 and 30 mg/kg/day, respectively, did not disclose any evidence of a teratogenic effect. A significant increase in foetal mortality was observed in the rabbit study at doses above 10 mg/kg/day. In rats a slight reduction in litter survival and weights was noted at doses above 100 mg/kg/day.
There are insufficient data to recommend the administration of lansoprazole during pregnancy. Lansoprazole should not be used during pregnancy, unless the benefit clearly outweighs the potential risk to the foetus.
 Animal studies indicate that lansoprazole is secreted into breast milk. There is no information on the secretion of lansoprazole into breast milk in humans. The use of lansoprazole during breastfeeding should be avoided.

4.7 Effects on Ability to Drive and Use Machines

The effects of this medicine on a person's ability to drive and use machines were not assessed as part of its registration.

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Lansoprazole reduces gastric acid secretions by inhibiting the H+/K+-ATPase (proton pump) of the parietal cells in the gastric mucosa, the terminal phase of acid secretion. The drug is effective in the treatment of acid related disorders of the upper gastrointestinal tract.
A single dose of 30 mg lansoprazole inhibits stimulated acid secretion by approximately 80%. Basal acid secretion and basal and stimulated secretion volumes are affected to a lesser degree.
After repeated dosing (for 7 days) 90% inhibition of stimulated acid secretion is achieved. Despite its short elimination half-life, lansoprazole has a prolonged pharmacological action, providing effective suppression of gastric acid secretion over 24 hours.
When used in combination with the recommended antibiotics, lansoprazole is associated with H. pylori eradication rates of up to 90%.

Clinical trials.

Helicobacter pylori. In clinical trials, the recommended dosage regimens were associated with H. pylori eradication rates of up to 90%. The best eradication rates were obtained with regimens which included clarithromycin. Trials which used lansoprazole in combination with only one antibiotic resulted in significantly lower eradication rates. Therefore, such regimens are not recommended.
Reflux oesophagitis.

Paediatrics.

In an open label, U.S. multicentre study, 66 children, 1 to 11 years of age, with GORD were assigned to receive an initial dose of either lansoprazole 15 mg capsules once daily, if the bodyweight was < 30 kg, or lansoprazole 30 mg capsules once daily, if the bodyweight was > 30 kg, administered for 8 to 12 weeks. The lansoprazole dose was increased up to 60 mg daily in some children after 2 weeks of treatment (see Table 3).
Treatment with lansoprazole also demonstrated significant reduction in frequency and severity of GORD symptoms (p < 0.001).
In a double blind, US multicentre study, 63 patients 12 to 17 years of age with proven GORD were randomised to receive either lansoprazole 15 mg once daily or 30 mg once daily for five days. Subjects in both groups demonstrated improvement in symptoms of reflux disease. A reduction in heartburn severity was shown to be statistically significant for patients treated with either 15 mg or 30 mg lansoprazole. The majority of patients (69% for lansoprazole 15 mg once daily and 74% for lansoprazole 30 mg once daily) reported that their reflux symptoms were better after treatment.

Adults.

In two double blind, placebo controlled multicentre studies (of 336 patients) examining the efficacy of lansoprazole 15 mg and 30 mg tablets in maintaining healed erosive reflux oesophagitis, lansoprazole was significantly superior to placebo in maintaining endoscopic and symptomatic freedom from disease. The time to median recurrence of either symptoms or endoscopic evidence of disease was less than 1 month for the placebo and greater than 12 months for 15 mg and 30 mg lansoprazole (p < 0.001). There was a slight trend for a better outcome with 30 mg lansoprazole, although this was not statistically significant.
A study in 266 patients, comparing lansoprazole 15 mg and 30 mg daily with ranitidine 300 mg twice daily, found both lansoprazole 15 mg and 30 mg increased the time to relapse and probability of no relapse in comparison to ranitidine. The percentage of patients who relapsed endoscopically during the 12 month maintenance period was 31% in the lansoprazole 15 mg group, 20% in the lansoprazole 30 mg group and 68% in the ranitidine group. The difference between the lansoprazole groups and the ranitidine was apparent from the earliest time point in the study and maintained throughout the 12 month period. Comparison of treatment groups with regard to symptom control showed similar superiority of lansoprazole over ranitidine (p < 0.001 for each comparison).
A study in 882 patients comparing lansoprazole 15 mg and 30 mg daily with omeprazole 20 mg daily showed endoscopic remission rates (after 12 months) of 75% with lansoprazole 15 mg daily, 88% with lansoprazole 30 mg daily and 89% with omeprazole 20 mg daily. The results demonstrate that lansoprazole 30 mg daily achieved significantly better remission rates compared to lansoprazole 15 mg daily and is of equal efficacy to omeprazole 20 mg daily.
The results of the 4 pivotal studies examining the use of lansoprazole in the long-term management of reflux oesophagitis are shown in Table 4.
Duodenal ulcer. In a study comparing lansoprazole 15 mg daily with placebo in 180 patients with endoscopically documented duodenal ulcer, the percentage of patients who remained healed after twelve months was significantly higher with lansoprazole than with placebo. Lansoprazole 15 mg was significantly superior to placebo in preventing endoscopic and symptomatic relapses of disease (see Table 5).
The maintenance studies discussed, using lansoprazole 15 mg and 30 mg, did not extend beyond 12 months.
Acid related dyspepsia. The efficacy of lansoprazole 15-30 mg daily has been examined in a total of 531 patients, compared with ranitidine (n = 171), omeprazole (n = 281) and placebo (n = 138).
The efficacy of lansoprazole (30 mg mane) was compared to ranitidine (150 mg bd) for the treatment of acid related dyspepsia in a double blind, parallel, 4 week study. The results are presented in Table 6.
There was also a significant difference in the usage of "rescue" antacid treatment in the two groups, with 67% of the lansoprazole group taking antacids in the first two weeks of treatment compared with 83% of the ranitidine group (p = 0.001).
In patients with symptoms of ulcer-like and reflux-like dyspepsia, lansoprazole 15 mg mane was compared to omeprazole 10 mg mane for a 4 week period in a double blind, parallel study. In the primary efficacy analyses in the intent to treat population, the study revealed that more patients were free of overall primary symptoms of dyspepsia in the lansoprazole treated group compared to the omeprazole treated group (p = 0.007 and p = 0.078, respectively) (see Table 7).
Nonulcer dyspepsia. A randomised, double blind parallel study 15 mg lansoprazole mane was compared to placebo in 269 patients suffering from nonulcer dyspepsia. In the intent to treat population the healing rate was 81/131 (61.8%) in the lansoprazole group after 2-3 weeks treatment, compared to 61/138 (44.2%) in the placebo group (p = 0.005). In the 3 month follow-up period, the recurrence of nonulcer dyspepsia symptoms was reported by 32/86 (37.2%) patients in the lansoprazole group and by 29/79 (36.7%) in the placebo group (p = 1.0). Healing was defined as the percentage of patients with no heartburn or acid regurgitation, as well as no nausea and vomiting and a reduction in the Visual Analogue Scale value of ≤ 20% during the last 5 days of treatment.

5.2 Pharmacokinetic Properties

Adults.

Absorption.

Lansoprazole is well absorbed and exhibits high bioavailability (80-90%) following an oral dose. The bioavailability has been shown to be affected by the presence of food; however, acid inhibition (which is an endpoint for efficacy), as measured from sampling of gastric juice in healthy volunteers, is not significantly affected by food. It was shown in one study that a.m. dosing produced higher mean gastric pH values than p.m. dosing.

Distribution.

Plasma protein binding is high (98%) and is gender and concentration independent. Binding does not change as a result of multiple dosing. The plasma elimination half-life in healthy subjects ranges from 1 to 2 hours following a single dose or multiple doses. Peak plasma levels occur within 1.5 to 2.0 hours after dosing in these subjects.
After IV administration, the volume of distribution is 29 ± 4 L, total clearance is 31 ± 8 L/h and elimination half-life is 0.9 ± 0.44 h.

Metabolism/ excretion.

Following absorption, lansoprazole is extensively metabolised and the metabolites are excreted by both the renal and biliary route. A study with 14C-labelled lansoprazole showed that up to 50% of the label was excreted in the urine, although unchanged drug does not appear to be excreted by this route; unchanged drug is eliminated, however, by biliary excretion.

Paediatric patients 1 to 11 years of age.

The pharmacokinetics of lansoprazole were studied in paediatric patients with GORD aged 1 to 11 years, with lansoprazole capsule doses of 15 mg once daily for subjects weighing < 30 kg and 30 mg once daily for subjects weighing > 30 kg. Lansoprazole pharmacokinetics in these paediatric patients were similar to those previously observed in healthy adult subjects. The mean Cmax and AUC values were similar between the two dose groups and were not affected by weight or age within each weight adjusted dose group used in this study.

Paediatric patients 12 to 17 years of age.

In a study of paediatric patients aged 12 to 17 years with GORD, the pharmacokinetics of lansoprazole were shown to be similar to those previously observed in healthy adult subjects. No statistically significant differences were observed between doses for Tmax, t1/2 or natural logarithms of dose normalised Cmax and AUC0-24. None of the selected covariates (bodyweight, age and gender) had any statistically significant effect on lansoprazole Tmax or the natural logarithms of dose normalised Cmax and AUC0-24.

5.3 Preclinical Safety Data

Genotoxicity.

Negative results were obtained in gene mutation assays and in an in vivo assay of chromosomal damage. In vitro assays of chromosomal damage showed evidence of chromosomal aberrations, though this may reflect cytotoxicity rather than genotoxic activity.

Carcinogenicity.

In a 2 year carcinogenicity study in rats, oral doses of 5, 15 or 50 mg/kg/day, 5 days per week produced gastric ECL cell hyperplasia and carcinoid tumours in a dose related manner in both male and female rats. The incidence of these effects was markedly higher in female rats. A "no effect" dose was not established for female rats. An increased incidence of benign Leydig cell tumours and testicular hyperplasia was also reported at dose levels of 15 mg/kg/day. Two repeat 2 year carcinogenicity studies in rats using doses ranging from 5-150 mg/kg/day, 7 days per week confirmed these findings. The effects of lansoprazole on human male fertility have not been evaluated.
In mice, a 78 week carcinogenicity study was performed at doses of 1.5, 5, 15 and 50 mg/kg/day, 5 days per week. No gastric ECL cell carcinoids were seen. In a repeat carcinogenicity study, mice were dosed with 15, 75, 150 or 300 mg/kg/day, 7 days a week. Terminal studies showed ECL cell hyperplasia, mucosal hyperplasia/ hypertrophy and glandular dilatation and vacuolation at all dosages. Carcinoids were found in occasional animals receiving 15, 150 or 300 mg/kg/day.
Hypergastrinaemia secondary to prolonged hypochlorhydria has been postulated to be the mechanism by which ECL cell hyperplasia and gastric carcinoid tumours develop.

Juvenile animal studies.

In an 8-week juvenile rat study, changes in male reproductive tissue (testes and epididymis) and heart (cardiac valve thickening) occurred at approximately 6-fold and 11-fold the expected human exposure, respectively, based on AUC (75-fold and 150-fold the expected human exposure based on body surface area). The findings reversed or trended towards reversibility after a 4-week drug-free recovery period. In a follow-up lansoprazole developmental sensitivity study, juvenile rats younger than postnatal day 21 (age equivalent to approximately 2 years in humans) were more sensitive to the development of heart valve thickening, with valve thickening occurring at lower exposure (approximately 4-fold the expected human exposure based on AUC) in animals dosed starting at postnatal day 14 (age equivalent to approximately 1 year in humans).
The relevance of these findings to paediatric patients less than 12 years of age is unknown. The findings in these studies are not relevant for patients 12 years of age and above.
