1 capsule contains 20 mg of Omeprazole (and sucrose).

Omeprazole, which is a racemic mixture of two enantiomers, is a specific inhibitor of the proton pump (H⁺/ K⁺ ATPase) in the parietal cells of the gastric mucosa. It reduces the secretion of hydrochloric acid in the stomach, both basal and stimulated. Omeprazole is not stable in an acidic environment and is therefore administered orally in the form of capsules filled with coated pellets. Absorption of omeprazole is rapid and the maximum concentration in blood occurs about 1-2 hours after administration. The bioavailability of omeprazole after a single oral administration is approximately 40%. Multiple administration once a day increases the bioavailability to about 60%. Omeprazole binds to plasma proteins in approximately 97%. It is completely metabolised by the cytochrome P450 system, mainly CYP2C19 (to hydroxyomeprazole) and partly by CYP3A4 (to the omeprazole sulfone). Almost 80% of an orally administered dose is excreted as metabolites in the urine; the remaining part with faeces. In patients with hepatic impairment the metabolic rate is reduced. In slow metabolisers (who do not have active CYP2C19 isoenzyme), the mean AUC is 5-10 times higher than in fast metabolisers (those with active CYP2C19 isozymes), mean C values_max they are also 3-5 times larger; however, these data do not give any consequences regarding the dosage of omeprazole.

Hypersensitivity to the active substance, substituted benzimidazoles or any of the excipients. Do not use with atazanavir. Do not use with Clarithromycin in patients with impaired hepatic function.

In patients with suspected or diagnosed peptic ulcer disease, as well as any disturbing symptoms (eg, significant unintentional weight loss, recurrent vomiting, swallowing difficulties, bloody vomiting or tarry stools), the cancerous background of the disease should be excluded, as omeprazole treatment may alleviate the symptoms of cancer and delay its diagnosis. Patients who have been on treatment for a long time (especially if the treatment lasts for more than a year) should remain under regular medical supervision. Some children with chronic conditions may need long-term treatment, but it is not recommended. There are no long-term data on the effect of omeprazole treatment on the maturation and growth of the body. Treatment with omeprazole may cause a slight increase in the risk of gastrointestinal infections with such bacteria asSalmonella spp. And Campylobacter spp.Omeprazole may reduce the absorption of vitamin B₁₂ (cyanocobalamin) due to hypo or achlorhydria; this should be taken into account during long-term treatment of patients with reduced vitamin B stores₁₂ or risk factors that favor its absorption. Patients treated with omeprazole for at least 3 months(in most cases for a year) severe hypomagnesaemia was noted; in patients who are envisaged for long-term treatment or who are taking proton pump inhibitors concomitantly with Digoxin or hypomagnesaemic agents (eg diuretics), Magnesium determination should be considered before starting omeprazole treatment and then periodically during treatment. Proton pump inhibitors, especially if used in high doses and prolonged (> 1 year), may slightly increase the risk of hip, wrist and spine fractures, mainly in elderly patients or in the presence of other recognized risk factors. Proton pump inhibitors can increase the overall risk of fractures by 10-40%; Patients at risk of osteoporosis should receive care in accordance with current clinical guidelines, and provide adequate amounts of vitamin D and calcium. Omeprazole, as a CYP2C19 inhibitor, may interact with drugs metabolised by this isoenzyme - be careful. Co-administration of omeprazole and Clopidogrel should be avoided. The use of omperazole with atazanavir is not recommended (reduction of atazanavir exposure). Due to the sucrose content, the drug should not be used in patients with rare hereditary disorders associated with fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase deficiency.

The preparation can be used during pregnancy. Omeprazole passes into breast milk, but there is no risk of adverse effects on the child when using the drug at therapeutic doses.

Common: headache, diarrhea, constipation, abdominal pain, nausea, vomiting, bloating. Uncommon: insomnia, dizziness, paresthesia, drowsiness, dermatitis, increased liver enzymes, dermatitis, pruritus, rash, urticaria, malaise, peripheral edema. Rare: leukopenia, thrombocytopenia, hypersensitivity reactions (eg fever, angioneurotic edema and anaphylactic reaction / shock), hyponatremia, agitation, confusion, depression, dysgeusia, blurred vision, bronchospasm, dryness or inflammation of the oral mucosa, gastrointestinal candidiasis , hepatitis with jaundice or without jaundice, alopecia, hypersensitivity to light, joint pain, muscle pain, interstitial nephritis, hyperhidrosis. Very rare: agranulocytosis, pancytopenia, hypomagnesaemia, aggression, hallucinations, hepatic failure, encephalopathy in patients with pre-existing liver disease, erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, muscle weakness, gynecomastia. The profile of adverse reactions in children was the same as in adults, both during short-term and long-term treatment.
