The swan song of FDA Commissioner Scott Gottlieb in the U.S. House Appropriations Committee came with the not-unexpected rueful farewells from both sides of the political aisle, but Gottlieb said one of his hopes for the agency is that it would push some compounding pharmacies operating under Section 503A of the Food, Drug and Cosmetic Act to register as 503B pharmacies. That would create more regulatory liability for those pharmacies, but Gottlieb said the FDA stands ready to assist any pharmacies with the tools and knowledge to make that transition.
