Abstract

Dipyridamole (DYP) is potent drug that prevents the thromboembolic risk. It has been clinically used for chronic treatment of angina pectoris treatment and during the valve replacement. heart valve replacement and long-term angina pectoris treatment and is well absorbed in the stomach with BCS class II drug and low oral bioavailability. The present research investigation was focused on the formulation of matrix tablets of Dipyridamole cocrystals and the evaluation of In vivo anticoagulant activity. The results of the study showed that the formulated matrix tablets of dipyridamole cocrystals showed improved efficacy in comparison with the plain drug by enhancing the pre-compression parameters such as bulk density, tap density, Carr's index, angle of repose and Hausner's ratio and post-compression parameters like thickness and weight variation, hardness and friability, In vitro dissolution parameters. The improved efficacy was confirmed by improvement in the pharmacodynamic parameters such as cutaneous bleeding time and clotting time indicative of enhanced bioavailability of dipyridamole. Thus, it can be concluded that the dipyridamole matrix tablets prove to be more effective in producing the anticoagulant effect in clinical practice as compared to the plain drug resulting in more patient compliance.
