Guide on Bulk Drug Substances for Compounding
FDA has issued a final guidance on Evaluation of Bulk Drug Substances Nominated for Use in Compounding Under Section 503B of the Federal Food, Drug, and Cosmetic Act. The document addresses the agency’s policies for developing a list of bulk drug substances that can be used in compounding. It also discusses FDA’s interpretation of “bulk drug substance for which there is a clinical need,” which is the statutory standard for compounding from bulk drug substances. The guidance also highlights criteria the agency generally intends to use to evaluate whether a bulk drug substance should be used by outsourcing compounding facilities.
