WEDNESDAY, April 4 (HealthDay News) -- Ibuprofen, the popular over-the-counter painkiller found in Advil and Motrin, may increase the odds of heart problems in patients who have osteoarthritis and are taking daily aspirin to help lower their cardiovascular risk, a new study finds.

The authors of the study, published in the Annals of the Rheumatic Diseases, speculated that ibuprofen may cancel out the cardio-protective effects of daily low-dose aspirin.

Use of ibuprofen and aspirin boosted arthritis patients' one-year heart attack and stroke risk ninefold compared to patients who were taking a cox-2 inhibitor pain reliever, the study found.

"This adds more data to the fact that perhaps ibuprofen inhibits aspirin in a clinically significant way," said Dr. E. Scott Monrad, director of interventional cardiology at Montefiore Weiler Division in New York City. "The most reassuring thing is that the event rate seen in the study, even in the high-risk arm, is still pretty low," added Monrad, who was not involved in the study.

Another expert agreed that it's not yet time to panic.

"You can't draw firm conclusions from this paper, but it raises the question that perhaps we should do a formal study looking at ibuprofen versus some of these other agents in patients who are at high cardiovascular risk and seeing if it really does hold up," said Dr. Robert Scott III, assistant professor of internal medicine at Texas A&M Health Science Center College of Medicine, College Station, and senior staff cardiologist at Scott & White Hospital.

Previous studies have suggested that drugs known as cox-2 inhibitors, as well as non-selective nonsteroidal anti-inflammatory drugs (NSAIDs), increase the risk of cardiovascular events. The cox-2 inhibitor Vioxx was withdrawn from the market in 2004 after studies found that it might double the risk of heart attacks, and the withdrawal of a second cox-2, Bextra, followed soon after.
