The same researchers at the Cleveland Clinic who first uncovered the lethal side effects of Vioxx may have saved even more lives with their latest discovery: A new diabetes drug on the brink of FDA approval appears to double a patient's risk of heart attack, stroke and death.
Scientists analyzed data on some 2,400 patients who took muraglitazar (Pargulva), a new drug that reduces blood fats and sugars, and about 1,400 who took a similar drug, pioglitazone (Actos), versus a placebo. During the study, 35 patients taking muraglitazar experienced a heart attack or stroke or died. And, when heart attacks and mini-strokes were considered alone, a patient's risk of a dangerous side-effect jumped by a factor of three.
This study (free text link below) was rushed to the Journal of American Medical Association's Web site for good reason: Two days before the study was released, the FDA found muraglitazar to be an approvable drug, although the agency asked drugmaker Bristol-Myers to address the drug's heart risks.
An FDA advisory committee ruled 8-1 to recommend muraglitazar for approval last month, yet didn't cite the drug's cardiac risks as significant... Now, do you have a better idea why I believe the FDA, as it's currently structured, is completely unable to adequately protect you?
