FDA Cautions Compounders on Bulk Sources
An FDA online statement says drug compounders should know their active pharmaceutical ingredient (API) and excipient suppliers and know if the suppliers are testing the components for purity and quality before they are purchased for use in compounding. The statement says that improper repackaging or lack of supply chain transparency regarding API or excipients can cause serious vulnerabilities in the supply chain and may lead to patient safety issues. Also, it says, repackaged API and excipient labels cannot be false or misleading regarding the identity of the product manufacturer.
The statement has examples of quality issues with bulk drug substances and excipients, related guidances and monographs, and a summary of FDA actions.
