Product Description

Omeprazols 20 mg Capsules is the first choice medicine in the treatment of the diseases that require gastric acid inhibition: duodenal ulcer; benign gastric ulcer; NSAID-associated duodenal or gastric ulcers and gastroduodenal erosions; duodenal ulcer associated with Helicobacter pylori; Helicobacter pylori eradication in combination with the appropriate antibacterial therapy; pathologic gastric hypersecretion in case of Zollinger-Ellison syndrome; gastric acid reduction during general anaesthesia; gastro-oesophageal reflux disease; acid reflux disease; acid related dyspepsia.

Product Mechanism of Action

Omeprazole inhibits gastric acid secretion. Omeprazole specifically blocks H+/K+- ATP enzyme system in the secretory surface of gastric parietal cells, blocks transport of hydrogen ions to stomach lumen and effectively inhibits both basal and stimulated gastric acid secretion. Omeprazole does not effect on receptors of acetylcholine and histamine. Omeprazole does not effect on evacuation of solid and liquid food from the stomach, inner factor secretion, and pepsin production.
