Three years after the FDA’s authority was broadened to allow it to require pharmaceutical manufacturers to conduct additional clinical studies or change medication labels (among other new powers), the FDA still has concerns about medication risks. Drug safety has always been an issue for the FDA, but given the recent high-profile troubles with the recalled painkiller Vioxx (rofecoxib), the contaminated blood-thinner heparin, and the sometimes fatal cardiac effects of the diabetes drug Avandia (rosiglitazone), it is clear to the FDA that it needs to have better oversight when it comes to medication safety.
