Substandard Generic Drugs Slip Past U.S. FDA Effort, Doctors Say

The Food and Drug Administration has failed to monitor the effectiveness of generics that make up 80 percent of medicines sold in the U.S., according to doctors and researchers who said new regulatory efforts aren’t enough.

Generic heart drugs made by some India-based companies don’t work as they should, said Preston Mason, a researcher at Brigham & Women’s Hospital in Boston who has studied the effectiveness of copies of Pfizer Inc.’s Lipitor made in the U.S. and abroad. That may be because some companies are cutting corners to save money, he said.
