Dipyridamole, also known by its brand name Persantine, is a medication commonly used to prevent blood clots and improve blood flow in individuals with certain medical conditions. It belongs to the class of drugs known as platelet aggregation inhibitors and is available in various forms such as tablets, capsules, and injectables. Dipyridamole works by inhibiting the uptake of adenosine, a chemical that affects blood flow, thereby increasing the amount of adenosine in the blood vessels and promoting vasodilation. This drug is primarily used in combination with other medications, such as aspirin, for its antiplatelet effects. It is mainly prescribed for individuals who have undergone heart valve replacement, coronary artery bypass surgery, or those at risk of thromboembolic disorders.
