What is the Origin of Drug Compounding?

Drug compounding is a deeply historical practice, predating mass-produced pharmaceuticals, where apothecaries prepared medicines from raw ingredients on demand. The term compound itself means "to combine or put together." Modern regulation, especially in the United States, distinguishes traditional compounding pharmacies (503A) from outsourcing facilities (503B) under the Food, Drug, and Cosmetic Act.

What is the Mechanism of Drug Compounding?

The process begins with a valid prescription for a patient who has a clinical need that cannot be met by an FDA-approved drug. The pharmacist meticulously selects and weighs active pharmaceutical ingredients (APIs) and excipients, following strict protocols and quality assurance measures. These raw materials are then combined to produce the final dosage form, ensuring the medication meets the prescribed specifications for purity, potency, and stability, thereby offering a personalized therapeutic option.

Drug Compounding

Meaning

The practice by a licensed pharmacist of creating a customized medication tailored to the specific needs of an individual patient, based on a practitioner’s prescription. This involves combining, mixing, or altering ingredients to formulate a drug product that is not commercially available, such as changing the dosage form, strength, or removing a non-essential allergen. Compounding is particularly relevant in hormonal health for creating bio-identical hormone preparations in unique delivery systems or concentrations.

Can 503a Pharmacies and 503b Facilities Coexist in Practice?

503A and 503B pharmacies coexist to provide both patient-specific and scalable, quality-assured compounded medications for personalized health.
