From Marketwatch.com:
Congress has approved a bill giving the Food and Drug Administration more authority to police prescription drugs, with a unanimous vote from the Senate Thursday following strong House approval earlier in the week.
The measure would require the FDA to monitor drugs after they’ve been approved for the market. It also grants the agency authority to order new studies, restrict distribution and require label changes for medications already on the market.
