  • Here is an additional general information about this medication active ingredient omeprazole:

    Pharmacological action

    Omeprazole is an inhibitor of H+ K+ ATPase. This medication inhibits the activity of H+-K+-ATPase in gastric parietal cells and thus blocks the final stage of hydrochloric acid secretion. This leads to a reduction in basal and stimulated secretion, regardless of the nature of the stimulus. Due to the reduction of acid secretion omeprazole reduces or normalizes the effects of acid in the esophagus in patients with reflux esophagitis.
    Omeprazole has a bactericidal effect on Helicobacter pylori. Eradication of H. pylori when omeprazole used with antibiotics allows to quickly arrest the symptoms, to take a high degree of healing of damaged mucosa and persistent long-term remission and reduce the likelihood of bleeding from the gastrointestinal tract.


    After oral administration Omeprazole is rapidly absorbed from the gastrointestinal tract. This drug penetrates the parietal cells of gastric mucosa. Plasma protein binding is about 95% (predominantly albumin). Omeprazole is biotransformed in the liver. Excreted by the kidneys - 72-80%, in the faeces - about 20%. T1/2 is 0.5-1 h. In patients with chronic liver diseases T1/2 increases up to 3 hours.
