Glossary
A compounded drug is prepared by a licensed pharmacy or an outsourcing facility rather than manufactured under an FDA approval. Compounding is lawful in defined circumstances and is a real part of medical practice; a compounded preparation is nonetheless not an approved drug.
The consequence is stated on every page of this site: compounded drugs are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or manufacturing quality. Lawful and reviewed are different properties, and a molecule can hold the first without the second.
Five of the 40 molecules this index covers are filed as compoundable under section 503A: a pharmacy may prepare them for an individual patient with a valid prescription.
Approved products are filed separately; a compounded version of an approved drug is restricted, not permitted by default.
