Antiplatelet medications are used to prevent heart attacks and strokes. They also have other uses, such as preventing blood clots in people with certain heart or blood vessel conditions. These medications work by stopping platelets in your blood from sticking together, which helps prevent clots from forming. Some antiplatelet medications are taken orally, while others are given as injections. Examples include clopidogrel (Plavix), prasugrel (Effient), ticagrelor (Brilinta), and aspirin / omeprazole DR (Yosprala). Your prescriber can help you choose the form that best fits your needs.
