The results indicated that patients who have been taking the drug for 18 months have twice the risk of suffering a heart attack or stroke than those taking a placebo. Vioxx had worldwide sales of $2.5 billion last year. While Merck's action was generally lauded, critics argue that earlier studies indicated this issue as well. The stock market reacted swiftly, reducing the price from $45 to $33. Merck and its investors braced for the inevitable lawsuits from those who believe they were harmed by the drug.
