Plavix (http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0000040)is a medication used by patients who may be at risk for a stroke or heart attack. It is classified medically as an antiplatelet drug. Plavix is also commonly
used to treat patients recovering from certain types of heart surgery. It prevents potentially serious clotting from occurring. The generic name for the drug is Clodipogrel. Effient (http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0000505)is also a medication that works as an antiplatelet. The primary difference between the two drugs seems to be circumstances in which they are prescribed. Effient is prescribed for patients recvering from angioplasty while Plavix is used to treat other types of heart related conditions.
