Persantin is used to improve blood circulation and prevent some health problems associated with blood clotting. The drug contains the active ingredient dipyridamole, which works to expand blood vessels and prevent platelet aggregation, which reduces the risk of clots. Persantin is usually prescribed as part of a treatment plan for patients suffering from diseases related to the heart or blood vessels, such as preventing strokes, especially in patients who have previously suffered from similar problems.
Persantin can also be used to improve blood flow in parts of the body that need better blood supply and to protect weak areas from damage due to lack of blood flow.
