For the second time in the past six months, a cardiology mainstay drug has lost patent protection and gone generic. Today the FDA announced that it had approved several generic versions of clopidogrel (Plavix), the antiplatelet drug that for many years was the second best-selling drug in the world. Last November the best-selling drug of all time, Lipitor (atorvastatin), another cardiology mainstay, went off patent, though it wasn’t until earlier this month that multiple generics became available.
The FDA said that it had approved 300 mg formulations of clopdiogrel from Gate Pharmaceuticals, Mylan Pharmaceuticals, and Teva Pharmaceuticals and 75 mg formulations from Apotex Corporation, Aurobindo Pharma, Mylan Pharmaceuticals, Roxane Laboratories, Sun Pharma, Teva Pharmaceuticals, and Torrent Pharmaceuticals.
In recent years the FDA approved two newer antiplatelet drugs that had been designed to take over the central role of Plavix in treating acute coronary syndromes. However, these drugs, prasugrel (Effient) and ticagrelor (Brilinta) have been struggling in the marketplace, and at this point appear very unlikely to command a significant share of the market.
Here is the FDA press release:
|FDA approves generic versions of blood thinner Plavix|
|The U.S. Food and Drug Administration today approved generic versions of the blood thinning drug Plavix (clopidogrel bisulfate), which helps reduce the risk of heart attack and stroke by making it less likely that platelets in the blood will clump and form clots in the arteries.Clopidogrel is FDA-approved to treat patients who have had a recent heart attack or a recent stroke, or have partial or total blockage of an artery (peripheral artery disease).
“For people who must manage chronic health conditions, having effective and affordable treatment options is important,” said Keith Webber, Ph.D., deputy director of the Office of Pharmaceutical Science in the FDA’s Center for Drug Evaluation and Research. “The generic products approved today will expand those options for patients.”
Clopidogrel has a boxed warning to alert health care professionals and patients that the drug may not work well for those with certain genetic factors that affect how the body metabolizes the drug. Patients can be tested for these genetic factors to ensure that clopidogrel is the right choice for them. Also, certain medicines, such as proton pump inhibitors Prilosec (omeprazole) and Nexium (esomeprazole), reduce the effect of clopidogrel, leaving a person at greater risk for heart attack and stroke.
Clopidogrel may cause bleeding, which can be serious and sometimes lead to death. While taking the drug, people may bruise and bleed more easily, be more likely to have nose bleeds, and it may take longer for all bleeding to stop. Clopidogrel is dispensed with a patient Medication Guide that provides important instructions on its use and drug safety information.
Gate Pharmaceuticals, Mylan Pharmaceuticals, and Teva Pharmaceuticals have gained FDA approval for 300 milligram (mg) clopidogrel. Apotex Corporation, Aurobindo Pharma, Mylan Pharmaceuticals, Roxane Laboratories, Sun Pharma, Teva Pharmaceuticals, and Torrent Pharmaceuticals have received approval for 75 mg clopidogrel.
Generic drugs approved by FDA are of the same high quality and strength as brand-name drugs. The generic manufacturing and packaging sites must pass the same quality standards as those for brand-name drugs.
Information about the availability of generic clopidogrel can be obtained from the manufacturers.
