The painkiller diclofenac isn't very popular in the U.S., but it's by far the most widely used non-steroidal anti-inflammatory drug, or NSAID, in the world.
A slew of studies, though, show diclofenac — sold under the brand names Voltaren, Cambia, Cataflam and Zipsor — is just as likely to cause a heart attack as the discredited painkiller Vioxx (rofecoxib), which was pulled from the U.S. market in 2004.
But evidence of the drug's cardiovascular risk hasn't translated to a reduction in use, a paper in the journal PLOS Medicine found. Diclofenac far outsells ibuprofen, naproxen, and other NSAIDs in 15 countries around the world.
