503a Compounding Pharmacies

Meaning

These facilities are state-licensed pharmacies that prepare customized medication formulations for individual patients based on a specific, patient-specific prescription order. Unlike large-scale manufacturers, a 503a pharmacy operates under Section 503A of the Federal Food, Drug, and Cosmetic Act, focusing on traditional compounding practices. Their clinical role involves tailoring dosage forms, strengths, or routes of administration to meet unique patient needs that commercially available drugs cannot satisfy. This individualized approach is particularly relevant in hormonal health for bioidentical hormone replacement therapy (BHRT). They are primarily regulated by state boards of pharmacy, not the FDA’s new drug approval process.
