YALE STUDY: NEARLY ONE THIRD OF DRUGS APPROVED BY REGULATORY BODIES HAVE SAFETY PROBLEMS. IMAGINE THE RISKS OF THOSE WITH NO APPROVAL!


Nearly one out of every three drugs approved by the Food and Drug Administration (FDA) have a new safety issue detected in the years after approval, says a Yale-led study. While most of the safety concerns are not serious enough to require withdrawal of a drug from the market, the finding highlights the need for ongoing surveillance of new drugs in the post-market period, said the researchers.

The findings were published May 9 in the Journal of the American Medical Association (JAMA).

To assess new drugs for safety and effectiveness, the FDA relies on premarket drug testing and clinical trials. Most of the trials involve fewer than 1,000 patients studied over a period of six months or less, making it difficult to detect safety issues that might be identified once more patients use the drug over a longer time period. To identify factors that might enhance patient safety and regulatory surveillance efforts, the Yale-led team analyzed data on new drugs approved between 2001 and 2010, with follow up through 2017.
