Description

This consists of an immediate release Esomeprazole Magnesium layer & an enteric-coated Naproxen core. As a result, Esomeprazole is released first into the stomach, prior to the dissolution of Naproxen in the small intestine. Naproxen is a NSAID with analgesic & antipyretic properties. The mechanism of action of Naproxen is to inhibit the prostaglandin synthesis. Esomeprazole is a proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the H+/k+ -ATPase in the gastric parietal cell by acting specifically on the proton pump, Esomeprazole blocks the final step in acid production, thus reducing gastric acidity.

With medicine: Concomitant use of NSAIDs may reduce the antihypertensive effect of ACE inhibitors, diuretics & beta-blockers Concomitant use of this tablet and warfarin may result in an increased risk of a bleeding complication. Esomeprazole inhibits gastric acid secretion & may interfere with the absorption of drugs where gastric pH is an important determinant of bioavailability (eg. Ketoconazole, iron salts and digoxin). With food & others: Administration of Naproxen & Esomeprazole together with high-fat food in healthy volunteers does not affect the extent of absorption of naproxen but significantly prolongs tmax by 10 hours and decreases peak plasma concentration (Cmax) by about 12%

Known hypersensitivity to any component of this tablet or substituted benzimidazoles. History of asthmay urticaria or other allergic-type reactions after taking aspirin or other NSAIDs. Use during the peri-operative period in the setting of coronary artery bypass graft (CABG) surgery.
