Another Wonder Drug Isn’t So Great Once It Goes Off Patent
Did you or your children use the blockbuster asthma drug Singulair? World sales of Mercks drug were about $5 billion a year until 2012 when its patent expired and it was the U.S.s seventh best-selling drug. But last month, data from an FDA committee were presented that acknowledge safety concerns about neuropsychiatric adverse events, including suicide and suicide attempts with the drug. Singulair was used by almost 9 million patients, many under 16, in less than two years according to FDA data and four deaths are linked to it. Like Vioxx, Fosamax, Paxil and Ambien, now that the patent has run out on Singulair, its dangers are being acknowledged.
Singulair is one of several asthma controller drugs that debuted in the last few years that are supposed to be added on to rescue inhalers and inhaled corticosteroids instead of replacing them. In addition to the cost of adding a third drug to two drugs that are already used, Singulair cost almost $200 a month until it went off patent.
