By the way, how many lives did Rezulin save because it was an effective diabetes drug verses how many liver deaths were associated with its use? This is not a rhetorical question - it was removed after a handful of possible cases of severe liver damage.
Believe me, I am not championing drug side effects, nor am i against the idea of widening post market initiatives. It is clear that unexpected side effects need to be watched out for, and that drug safety is an ongoing concern that involves more than just the target organ.
But drug safety and cost/benefit analyses mean looking at more than just a weakly observed mathematically determined association. These shadows will be found in many more places the harder we look for them. And great drugs will be unfairly targeted and destroyed. The cost is too high. Two TZDs down. One left to go. By the way, did I forget to mention that these drugs are perhaps the best drugs we have for type 2 diabetes - i see that I began my post this way - so I've come full circle.
