Drug Mode of Action ::  

Naproxen, a propionic acid derivative, is a prototypical NSAID. It reversibly inhibits the cyclooxygenase-1 and -2 (COX-1 and -2) enzymes, thus resulting in reduced synthesis of prostaglandin precursors. It can inhibit platelet aggregation, has anti-inflammatory, analgesic and antipyretic actions.

Drug Interactions ::

May enhance methotrexate toxicity. Reduced BP response to ACE inhibitors or angiotensin II receptor antagonists. Increased risk of serious GI events (e.g. ulcer) w/ aspirin. Increased risk of GI bleeding w/ warfarin. May reduce the natriuretic effects of furosemide or thiazide diuretics. May increase serum lithium concentrations and reduce renal lithium clearance. Delayed absorption w/ antacids, colestyramine or sucralfate. May interfere w/ the antihypertensive effects of ?-blockers (e.g. propranolol). May increase serum levels w/ probenecid.
