Dipyridamole by Teva Canada Limited
How does this medication work? What will it do for me?
Dipyridamole belongs to the class of medications called platelet aggregation inhibitors or antiplatelets. It is used to prevent blood clots that may occur after a heart valve replacement. It works by preventing certain types of blood cells, called platelets, from sticking together. It is also used for certain types of tests for the heart that examine how well blood is flowing through the heart.
