WASHINGTON (AP) – State pharmacy officials on Thursday threw their support behind a proposal giving the Food and Drug Administration authority over large compounding pharmacies, in an effort to head off more outbreaks tied to contaminated medications.

The head of the National Association of Boards of Pharmacy told Senate lawmakers that his group welcomes FDA action against pharmacies like the one that triggered a deadly meningitis outbreak last year. The group’s endorsement is a key step in bringing stricter oversight to the compounding industry, which has long operated in a gray area between state and federal regulation.
