Combining Dipyridamole and Naproxen is a major interaction and should generally be avoided without close medical supervision.
Combining naproxen with dipyridamole significantly increases your risk of bleeding, especially in the stomach or intestines. You should avoid taking these medications together unless specifically instructed by your doctor.
Mechanism: Naproxen, an NSAID, inhibits cyclooxygenase enzymes, reducing prostaglandin synthesis and impairing platelet aggregation. Dipyridamole is an antiplatelet agent that also inhibits platelet function. The co-administration of these two drugs leads to an additive antiplatelet effect, significantly increasing the risk of bleeding.

Dipyridamole
Mechanism of Action Dipyridamole inhibits the uptake of adenosine into platelets, endothelial cells and erythrocytes in vitro and in vivo ; the inhibition occurs in a dose-dependent manner at therapeutic concentrations (0.5 mcg/mL to 1.9 mcg/mL). This inhibition results in an increase in local concentrations of adenosine which acts on the platelet A 2 -receptor thereby stimulating platelet adenylate cyclase and increasing platelet cyclic-3',5'-adenosine monophosphate (cAMP) levels. Via this mech…
Naproxen
Naproxen has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of naproxen, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Naproxen is a potent inhibitor of prostaglandin synthesis in vitro. Naproxen concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in ani…
