ATX: A.02.B.C.01 Omeprazole
A specific proton pump inhibitor: Inhibits H+ K+ ATPase activity in gastric parietal cells, blocking the final stage of hydrochloric acid secretion, thereby reducing acid production.
Omeprazole is a prodrug and is activated in the acidic environment of the secretory tubules of the parietal cells of the stomach.
The effects are dose-dependent and provide effective inhibition of basal and stimulated acid secretion, regardless of the nature of the stimulus. The antisecretory effect after taking 20 mg occurs within the first hour, maximum in 2 hours. Inhibition of 50% of the maximum secretion lasts for 24 hours. Single daily intake provides rapid and effective inhibition of gastric secretion during the day and night, which reaches its maximum after 4 days of treatment and disappears by the end of 3-4 days after the end of intake. In patients with duodenal ulcer disease, administration of 20 mg of omeprazole maintains intragastric pH above 3 for 17 hours.
Absorption is high, time to reach maximum concentration (Tmax) is 0.5-3.5 h, bioavailability is 30-40% (increases to almost 100% in liver failure); having high lipophilicity, easily penetrates into the parietal cells of the stomach, binding to plasma proteins is 90-95% (albumin and acidic alpha1-glycoprotein). The elimination half-life (T1/2) is about 0.5-1 h (in hepatic insufficiency – 3 h), total plasma clearance is 500-600 ml/min. It is almost completely metabolized in the liver with participation of cytochrome P450 (CYP) enzyme system with formation of six pharmacologically inactive metabolites (hydroxyomeprazole, sulfide and sulfone derivatives, etc.). It is an inhibitor of CYP2C19 isoenzyme. Excretion by the kidneys (70-80%) and with bile (20-30%). In chronic hepatic insufficiency, excretion decreases in proportion to the decrease in creatinine clearance. In elderly patients excretion decreases, bioavailability increases.

How to take, the dosage
Overly with a small amount of water (the contents of the capsule must not be chewed) before meals.
Penal ulcer in the acute phase – 20 mg per day for 2-4 weeks (in resistant cases up to 40 mg per day).
Peptic ulcer disease in the phase of exacerbation and erosive-ulcerous esophagitis – 20-40 mg per day for 4-8 weeks.
Errotic ulcerative lesions of the gastrointestinal tract caused with taking NSAIDs – 20 mg per day for 4-8 weeks.
Eradication of Helicobacter pylori – 20 mg 2 times per day for 7 or 14 days (depending on the regimen used) in combination with antibacterial agents.
For prevention of recurrence of peptic ulcer disease of the stomach and duodenum – 20 mg per day.
For the prevention of recurrence of reflux esophagitis – 20 mg per day for a long time (up to 6 months). Administration on demand (symptomatic treatment).
Zollinger-Ellison syndrome – the dose is adjusted individually depending on the initial level of gastric secretion, usually starting at 60 mg per day. If necessary, the dose is increased to 80-120 mg per day, in which case it is divided into 2 doses.
In patients with severe hepatic insufficiency, the daily dose should not exceed 20 mg.
Interaction
Special Instructions
Before starting therapy, the presence of a malignant process (especially with gastric ulcers) should be ruled out, since treatment, by masking symptoms, can delay the correct diagnosis.
Taking at the same time with food does not affect its effectiveness.
In special cases if it is difficult to swallow the whole capsule, the contents may be swallowed after opening or disgorging the capsule, or the capsule contents may be mixed with a slightly acidified liquid (juice, yogurt) and the resulting suspension may be used within 30 minutes.
