Packing

Pharmacological action

Omeprazole - proton-inhibiting proton pump, antiulcer.

Pharmacodynamics

Omeprazole inhibits the enzyme H + - K + -ATPase ("proton pump") in the parietal cells of the stomach and thereby blocks the final stage of hydrochloric acid synthesis. This leads to a decrease in the level of basal and stimulated secretion, regardless of the nature of the stimulus. After a single oral administration, the action of omeprazole occurs within the first hour and lasts for 24 hours, the maximum effect is achieved after 2 hours. In patients with peptic ulcer of the duodenum, taking 20 mg of omeprazole maintains an intragastric pH = 3 for 17 hours. After discontinuation of the drug, secretory activity is fully restored after 3-5 days.

Pharmacokinetics

Omeprazole is rapidly absorbed from the gastrointestinal tract, Cmax in plasma is reached after 0.5–1 hours. Bioavailability is 30–40%. Plasma protein binding is about 90%. Omeprazole is almost completely metabolized in the liver. T1 / 2 - 0.5–1 hours. It is excreted mainly by the kidneys in the form of metabolites. In chronic renal failure, excretion decreases in proportion to a decrease in creatinine clearance. In elderly patients, excretion decreases, bioavailability increases. With liver failure, bioavailability is 100%, T1 / 2 - 3 hours.
