Cytopan is a combination medication that contains two active ingredients: Clopidogrel (75mg) and Aspirin (200mcg). It is used to prevent blood clots from forming and reduce the risk of heart attack and stroke in people who have a history of such conditions or who are at high risk for them. Clopidogrel is an antiplatelet agent that works by preventing platelets from sticking together and forming clots, while aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that also helps prevent blood clots by reducing the stickiness of platelets. Cytopan is typically taken once daily or as directed by a healthcare provider.
