Diabetes drug rezulin

The company did provide FDA with the promised data from the additional trials a week after the approval. It revealed a rate of liver abnormalities that was not at all "very, very similar" in the patients who got the new drug; it was substantially greater. But the drug had already been approved and the new information didn't receive widespread attention. Rezulin's initial approval required that it be used only for patients already taking insulin, limiting its potential utilization and thus its market share. But Parke-Davis quickly sought further permission to market the drug as a stand-alone therapy for diabetes. This would greatly increase the product's commercial potential, but would also expose far more patients to its risks. Backed by a huge marketing campaign featuring its novel mode of action, sales of Rezulin took off. But by October 1997, when it had been on the market for just eight months, concern began to grow over a steady flow of reports describing patients who developed severe and unexpected liver damage while taking the drug. In preparation for a meeting with the FDA on October 24, Parke-Davis ran a computer tabulation of all subjects in its early premarketing clinical trials whose blood tests suggested liver abnormalities. But before a company physician reported these findings to the FDA, he tightened the criterion for "abnormal" in patients who got the new product but not for those in the placebo group, obscuring the elevated risk. ParkeDavis then obtained FDA permission to use the lower number of liver cases in its official product warnings, without revealing that the initial estimate had been considerably larger. Normally, we estimate a drug's potential for liver damage by measuring whether enzymes from that organ leak into the bloodstream. This blood test is a useful indicator of the severity of liver damage: normal levels are reassuring, modest elevations three times the normal range ; raise questions, and much higher levels as high as ten or twenty times the normal range ; are usually a sign of substantial damage. But in reporting these results to the FDA, companies sometimes fold together all abnormal liver tests under the broad category of "greater than three times normal, " even if a large proportion of such patients have elevations that were far higher--a clear sign of widespread liver cell destruction. This is akin to asking your child how his day went at school and being told that he had a squabble with the teacher, when in fact he had hacked her to death with a machete. A fair report of the event would have mentioned something about stab wounds and not merely categorized it under the rubric "squabble." By the autumn of 1997, 135 cases of severe liver damage had been reported in Rezulin patients, including at least five that were fatal. All the cases had occurred in the United States or Japan. Drug safety surveillance is an international field, and news about adverse events in one country is rapidly communicated around the world. Looking back, that period provides a fascinating contrast in how regulatory authorities and companies in different countries can assess the very same data and come to vastly different conclusions. The drug was approved for use in the United Kingdom a few months later than in the United States. It was sold there under a licensing agreement with the British pharmaceutical firm Glaxo-Wellcome, which did not begin marketing it until September 1997. Within six weeks, Glaxo officials in London became concerned about the rapidly increasing rate of reports of liver damage. The affected patients often had nothing in their histories to suggest that they would be susceptible to this life-threatening problem. It was also becoming clear that stopping the drug when the problem was first detected.

Numerous classes of drugs--including anticholinergics, antihistamines, antipsychotics, cannabinoids, benzodiazepenes, 5HT antagonists, and glucocorticoids--are used for their antiemetic effect. Side effects of antiemetics that may impair driving performance include sedation, blurred vision, headache, confusion, and dystonias. Significant impairment may be present even in the absence of subjective symptoms. Patients should be counseled about side effects and their potential to impair driving performance, and should be advised that they may experience impairment even in the absence of subjective symptoms.

According to a knowledgeable fda physician, a large proportion of physicians at fda familiar with rezulin s dangers think the drug should be taken off the market. Anticonvulsant drugs are widely used in the management of eclampsia, as well as in severe hypertensive disease and pre-eclampsia, in an attempt to prevent the occurrence of eclamptic seizures.
