PREVACID NapraPAC 375 Chemical Information

lansoprazole - A substituted benzimidazole prodrug with selective and irreversible proton pump inhibitor activity. Lansoprazole prodrug is converted to an active sulfonamide derivative in the acidic environment of the gastric parietal cell; the sulfonamide derivative binds to the gastric proton pump H+/K+ ATPase and forms a stable disulfide bond with the sulfhydryl group near the potassium-binding site on the luminal side, resulting in inactivation of the ATPase and a reduction in gastric acid secretion. This agent does not have anticholinergic or histamine H2 -receptor antagonistic properties.

naproxen - A propionic acid derivative and a non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory, antipyretic and analgesic activities. Naproxen inhibits the activity of the enzymes cyclo-oxygenase I and II, resulting in a decreased formation of precursors of prostaglandins and thromboxanes. The resulting decrease in prostaglandin synthesis is responsible for the therapeutic effects of naproxen. Naproxen also causes a decrease in the formation of thromboxane A2 synthesis, by thromboxane synthase, thereby inhibiting platelet aggregation.
