FDA Begins Restricting Bulk Compounding With First DQSA Determinations

FDA has taken its first action on the 503B bulks list since DQSA was enacted five years ago by banning two bulk drug substances – vasopressin and nicardipine hydrochloride – from the list of bulk drug substances that outsourcing facilities can use to compound drugs. The agency also issued final guidance addressing its polices for developing the 503B bulks list. Legal observers say that these actions should prompt outsourcing facilities to be wary of using bulk drug substances not approved by FDA.
