The Food & Drug Administration recently approved three generic versions of simvastatin (Zocor, Merck), the largest-selling drug yet to be opened to generic competition. For the next 180 days, Teva will have exclusive rights to sell the 5-, 10-, 20-, and 40-mg dosages of simvastatin and Ranbaxy will have the rights to sell the 80-mg dosage. In addition, Dr. Reddy's Laboratories will sell all five dosages under an agreement with Merck to be the authorized generic manufacturer of the drug.
