Clopidogrel is a medication used to prevent blood clots in patients with certain cardiovascular conditions, such as a history of heart attack or stroke. It belongs to a class of drugs known as antiplatelets, which work by preventing blood platelets from sticking together and forming clots. Clopidogrel is typically prescribed in combination with aspirin for maximum effectiveness in preventing clot formation. Researchers have conducted numerous studies to evaluate the safety and efficacy of clopidogrel in various patient populations and to identify any potential side effects or drug interactions. Studies have also investigated different dosing regimens and alternative medications to determine the optimal treatment approach for patients at risk for blood clots.
