503a Compounding Pharmacies

Meaning

A 503a compounding pharmacy prepares custom medications for individual patients based on a specific prescription from a licensed practitioner. These pharmacies operate under state board of pharmacy regulations, distinct from conventional drug manufacturers. They are exempt from certain FDA registration and approval requirements, provided they adhere to specific conditions outlined in the Federal Food, Drug, and Cosmetic Act. Their primary focus is on patient-specific needs, not mass production.
