Painkiller risk goes beyond Vioxx

Heart attack and heart failure patients have a higher risk of a second heart attack or death if they take painkillers, including the generic drug ibuprofen and Celebrex, made by Pfizer, a Danish study has found.

Patients who had suffered a heart attack and were taking Vioxx, a painkiller that has been withdrawn from the market, had 2.7 times the risk of having another heart attack or dying compared with patients not taking painkillers, according to research presented Tuesday at the American Heart Association meeting in New Orleans. Patients taking Celebrex had double the risk; patients taking the generic diclofenac had 1.9 times the risk, and those taking ibuprofen had 1.3 times the risk, the study found.

Based on the findings, doctors should avoid prescribing nonsteroidal anti-inflammatory drugs for these patients, or give them at low doses, a researcher said.

Also Tuesday, researchers said that the risk of heart attacks and strokes for heart-stent patients taking the anti-clotting drug Plavix increased if they also took anti-ulcer medicines like Nexium.

Doctors implant about two million stents a year and often prescribe blood thinners like Plavix, made by Bristol-Myers Squibb and Sanofi-Aventis, to avoid clots. But the drugs raise the risk of stomach bleeding, so they also prescribe Nexium, made by AstraZeneca, or a rival drug in a group known as proton pump inhibitors. About a third of these patients suffered complications within a year, the study said.
