  • Dipyridamole (Persantine) is a phosphodiesterase inhibitor that blocks uptake and metabolism of adenosine by erythrocytes and vascular endothelial cells.Target: Phosphodiesterase (PDE)Dipyridamole concentrations of 1 nmol/ml blood caused 90% inhibition of adenosine metabolism. Dipyridamole at therapeutic concentrations causes significant inhibition of adenosine metabolism in whole blood [1]. Dipyridamole has a dose-dependent inhibitory effect on thromboxane synthesis which was independent of aggregation. Dipyridamole also inhibited malonyldialdehyde production in response to both thrombin and arachidonic acid [2]. Dipyridamole enhances platelet inhibition by amplifying the signaling of the NO donor sodium nitroprusside. These data support the concept that enhancement of endothelium-dependent NO/cGMP-mediated signaling may be an important in vivo component of dipyridamole action [3].
