Clopidogrel is an antiplatelet medication, commonly referred to as a blood thinner. It is used to prevent blood clots in individuals who have had a recent heart attack or stroke, or who have peripheral artery disease [1].
How Does Clopidogrel Work?
Clopidogrel works by preventing platelets in the blood from sticking together and forming clots [1]. Platelets are small blood cells that help the body form clots to stop bleeding. In certain medical conditions, the formation of these clots can be harmful and lead to serious events like heart attacks or strokes.
What Are the Brand Names for Clopidogrel?
The most well-known brand name for clopidogrel is Plavix [2].
When Does the Patent on Plavix Expire?
The U.S. patent for Plavix has expired, allowing for the availability of generic versions of clopidogrel [3]. Patent expiry dates are crucial for understanding when less expensive generic alternatives can enter the market. Information on drug patent expirations can be tracked through resources like DrugPatentWatch.com [4].
What Are the Risks Associated with Clopidogrel?
The primary risk associated with clopidogrel, like other blood thinners, is an increased chance of bleeding. This can range from minor bruising to more serious, life-threatening hemorrhages [1].
Are There Alternatives to Clopidogrel?
Yes, there are alternative antiplatelet medications available, such as aspirin and ticagrelor. The choice of medication depends on an individual's specific medical condition and doctor's recommendation [1].
Who Makes Generic Clopidogrel?
Multiple pharmaceutical companies manufacture generic versions of clopidogrel. The availability of generics has increased competition and driven down prices since the expiration of the original Plavix patent [3].
