Description

General description

Omeprazole is a benzimidazole derivative, a weak base and is lipophilic in nature. This compound is pH sensitive and does not exists in its original form at low pH.

Application

Omeprazole has been used as an atypical cytochrome P450 (CYP) 1A2 inducer in Dulbecco′s modified eagle′s medium (serum free) to study the effects of inducers on CYP activities in human hepatocytes and also to compare with other classical aryl hydrocarbon receptor ligands.

Biochem/physiol Actions

Omeprazole binds covalently to proton pump (H⁺, K⁺-ATPase) and inhibits gastric secretion. It is useful in ameliorating the effects of peptic oesophagitis, duodenal and gastric ulcer. Omeprazole is preferred over antagonists of histamine H2-receptor and ranitidine for its higher efficiency. It is also useful in treating Zollinger-Ellison syndrome.
