Plavix is a brand name medication used to prevent blood clots. However, there are synonyms for "Plavix" that refer to the generic name of the drug, clopidogrel bisulfate. These synonyms include Clodrel, Plagerine, Clopivas, and Clavix. These medications work by preventing platelets in the blood from sticking together, reducing the risk of blood clots forming in the arteries or veins. Clopidogrel bisulfate is often prescribed to patients who have had a heart attack, stroke, or peripheral artery disease. These synonyms can be used interchangeably with Plavix, as they all contain the same active ingredient and have the same effects on the body.
