Clots are a serious complication that can cause strokes, heart attacks, or blocked blood vessels in the lungs (pulmonary embolisms). Dipyridamole belongs to a class of drugs known as platelet inhibitors. It helps to keep blood flowing by stopping platelets from clumping together and by keeping heart blood vessels open.
