Proton Pump Inhibitor

Omeprazole belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress gastric acid secretion by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface of the gastric parietal cell. Because this enzyme system is regarded as the acid (proton) pump within the gastric mucosa, omeprazole has been characterized as a gastric acid-pump inhibitor, in that it blocks the final step of acid production. This effect is dose-related and leads to inhibition of both basal and stimulated acid secretion irrespective of the stimulus.Clinical advantage of omeprazole mups tablet compared to conventional modified-release omeprazole tablets and pellet-filled omeprazole capsules: Ensures greater bioavailability Ensures uniform emptying of micro pellets from stomach into small intestine facilitates rapid dissolution of enteric coating and drug release resulting in early Tmax and Cmax (peak time and peak plasma concentration) Ensures lesser possibility of dose dumping Is a combination of fast acting and sustained action Ensures uniform drug release Once daily dosing Ensures lesser chance of localized irritation Ensures better and more uniform drug absorption Better than capsules in reducing the esophageal residence time Minimizes fluctuation in plasma concentration of drug

Omeprazole is metabolized through CYP2C19 . When starting or stopping treatment with Omeprazole should be taken into account potential interactions with medicines which are CYP2C19 metabolized.

Omeprazole is contraindicated in those patients who have known hypersensitivity to any other components of the formulation.

Not known to be harmful. Omeprazole can be used during pregnancy. Omeprazole is excreted in breast milk but is not likely to influence the child when therapeutic doses are used.

Omeprazole tablet should be used carefully if the patient has severe liver dysfunction and severe renal impairment.

Store in a cool (below 30° C) and dry place, protected from light and moisture.
