Merck looking for new arthritis drugs to market after demise of Vioxx
The arthritis medication at the centre of one of the biggest drug recalls in history was associated with dozens of heart problems and strokes - at least four of them fatal - during the study that led to its demise.

Vioxx was pulled off pharmacists' shelves around the world on Thursday after its maker, Merck and Co., withdrew its top-selling anti-inflammatory drug from the market due to safety concerns. Researchers conducting the study found an increased risk of cardiovascular problems with patients taking the drug for at least 18 months.
