Specifically, around 10 percent of drugs which make it to Phase I clinical trials eventually get approved by the FDA, and many more drug candidates fail before reaching Phase I clinical trials. So, the FDA has to very carefully reject the vast majority of drugs which pharmaceutical companies attempt to get approved. Since most of the drugs which are submitted for FDA approval don’t meet the FDA standards, it is not surprising that some drugs with negative side-effects get approved.
