Mechanism Of Action and Pharmacodynamic Effects Click here for help
Dipyridamole is primarily a phosphodiesterase inhibitor, but also shows inhibitory activity against the equilibrative nucleoside transporter (eg SLC29A1). By inhibiting phosphodiesterase, dipyridamole raises cAMP levels, blocking the release of arachidonic acid from membrane phospholipids and reducing thromboxane A2 activity; effects which combine to inhibit platelet function. Dipyridamole further inhibits platelet aggregation by directly stimulating the release of prostacyclin, which also increases platelet cAMP levels (inhibits platelet function).
