With prescription drugs Vioxx and Bextra already pulled from the market, a study has raised disturbing questions about the heart safety of long-term use of over-the-counter pain relievers such as Advil, Motrin and Aleve.
Smokers in Norway who took such drugs for at least six months had twice the risk of dying of a heart attack, stroke or other heart-related problem.
The findings came from a study of whether these pain relievers could prevent oral cancer. The drugs did, in fact, cut the risk of developing oral cancer in half, but the deaths that were prevented were offset by the increased risk of dying from cardiovascular disease, according to the study, reported Monday at an American Association for Cancer Research conference in Anaheim.
The study was relatively small -- 908 people -- and involved people prone to heart problems and cancer because they smoked. But specialists said it supports the Food and Drug Administration's recent decision to warn about long-term use of all such painkillers except aspirin.
The findings add to the suspicion that the heart risk extends beyond the so-called cox-2 drugs -- Bextra, Vioxx and Celebrex -- to the larger family of medications known as non-steroidal anti-inflammatory drugs, or NSAIDs, which include naproxen, ibuprofen and virtually all other over-the-counter pain relievers except acetaminophen or Tylenol.
In recent months, many doctors have switched patients to these over-the-counter medications, believing them to be safer alternatives.
"To the best of our knowledge, these are the first data to support putting a box warning on NSAIDs, not just cox-2s," said Dr Andrew Dannenberg, a Cornell University scientist who helped do the Norway study.
Vioxx was pulled from the market last fall when a different study, testing whether it could prevent colon cancer, showed a higher heart disease risk.
