Clopidogrel
Clopidogrel
Clopidogrel (pronounced kloh-PID-oh-grel) is a medication used to prevent blood clots in people who have recently had a heart attack or stroke, and in those with certain disorders of the heart or blood vessels.
Etymology
The name "Clopidogrel" is derived from the French words "clot" and "pied", which mean "clot" and "foot" respectively. This is in reference to the drug's ability to prevent blood clots.
Usage
Clopidogrel is used alone or with aspirin to prevent serious or life-threatening problems with the heart and blood vessels in people who have had a stroke, heart attack, or severe chest pain. This is usually prescribed by a doctor and is available under the brand name Plavix.
Mechanism of Action
Clopidogrel works by preventing platelets (a type of blood cell) from collecting and forming clots. It does this by blocking a certain enzyme that platelets need in order to clot.
Side Effects
Common side effects of Clopidogrel include bruising and excessive bleeding. Serious side effects can include allergic reactions, liver problems, and a severe skin condition known as Stevens-Johnson syndrome.
