Gastrostat, 100 mg 90 pcs.

Pharmacotherapeutic group: gastroprotective agent.

The ATX code: A02BX14

Pharmacological properties

Pharmacodynamics

Rebampid increases prostaglandin E2 (PGE2) content in gastric mucosa and increases PGE2 and GI2 content in gastric juice content. It has cytoprotective effect on the gastric mucosa under the damaging effects of ethanol, acids and alkalis, acetylsalicylic acid.

It promotes the activation of enzymes that accelerate the biosynthesis of high-molecular-weight glycoproteins, and increases the content of mucus on the surface of the gastric wall.

Helps improve the blood supply to the gastric mucosa, activates its barrier function, activates alkaline secretion of the stomach, increases the proliferation and metabolism of gastric epithelial cells, cleanses the mucosa of hydroxyl radicals and suppresses superoxides, produced by polymorphonuclear leukocytes and neutrophils in the presence of Helicobacter pylori, protects gastric mucosa from bacterial damage, has gastroprotective effect when the mucosa is affected by non-steroidal anti-inflammatory drugs (NSAIDs).

Pharmacokinetics

Absorption when taken orally is high. After administration at a dose of 100 mg, the peak plasma concentration (C_max) is reached after approximately 2 hours and is 340 ng/ml. The elimination half-life (T_1/2) is approximately 1.0 h. Repeated administration of the drug does not cause its cumulation in the body.

About 10% of the drug is excreted by the kidneys, mostly unchanged. When taken in a dose of 600 mg, traces of the hydroxylated metabolite can be excreted.

In in vitro experiments it has been shown that 98.4% to 98.6% of the drug is bound to plasma proteins.

Indications

Gastric ulcer. Chronic gastritis with increased acid-forming function of the stomach in the acute stage, erosive gastritis. Preventing the occurrence of damage to the mucous membrane while taking non-steroidal anti-inflammatory drugs. Can be used as part of combination therapy.

Approximately 10% of the drug is excreted by the kidneys, mainly unchanged. When taken at a dose of 600 mg, traces of the hydroxylated metabolite can be isolated.

In vitro experiments have shown that from 98.4% to 98.6% of the drug is bound by plasma proteins.
