Anti-platelet therapy: phosphodiesterase inhibitors

Dipyridamole inhibits platelet aggregation in whole blood, as assessed by impedance aggregometry, but not in platelet-rich plasma both in vitro and ex vivo, by blocking the reuptake of adenosine [72, 73]. A stronger antiplatelet effect of dipyridamole in whole blood than in plasma was confirmed using different laboratory methods [74–77].
