Combining Cilostazol and Naproxen is a major interaction and should generally be avoided without close medical supervision.
Combining naproxen with cilostazol greatly increases your risk of bleeding, especially in the stomach or intestines. This combination should generally be avoided due to severe bleeding potential.
Mechanism: Naproxen, a non-selective NSAID, inhibits cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis and impairing platelet aggregation. Cilostazol is a phosphodiesterase-3 inhibitor that also directly inhibits platelet aggregation. The concurrent use of these agents results in additive antiplatelet effects and increased gastrointestinal mucosal damage, significantly elevating bleeding risk.

Cilostazol Overview
Cilostazol is a medication that belongs to a class of drugs called phosphodiesterase III inhibitors. It is primarily used to help people with a condition called intermittent claudication, which causes leg pain during exercise due to poor blood flow. By improving blood flow and preventing blood clots, cilostazol helps reduce these symptoms and allows patients to walk further without pain.

Cilostazol
Cilostazol and several of its metabolites inhibit phosphodiesterase III activity and suppress cAMP degradation with a resultant increase in cAMP in platelets and blood vessels, leading to inhibition of platelet aggregation and vasodilation, respectively. Cilostazol reversibly inhibits platelet aggregation induced by a variety of stimuli, including thrombin, ADP, collagen, arachidonic acid, epinephrine, and shear stress. Cardiovascular effects: Cilostazol affects both vas…
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…
