What is the Origin of Section 503b?

This section was established by the Drug Quality and Security Act (DQSA) of 2013 in response to widespread public health concerns regarding the quality and safety of compounded medications produced in large volumes. The legislation aimed to formalize a regulatory middle ground, imposing a high level of federal oversight and quality assurance on large-scale compounders. The name is a direct reference to the section of the federal law that defines the outsourcing facility.

What is the Mechanism of Section 503b?

The core mechanism of Section 503B is the requirement for cGMP compliance, which dictates strict controls over facility design, equipment calibration, process validation, and batch testing for potency, sterility, and endotoxins. This regulatory framework ensures that the compounded products maintain consistent quality and integrity. By operating under cGMP, 503B facilities provide a reliable source of customized or non-commercially available medications to healthcare systems.

Section 503b

Meaning

Section 503B refers to a provision of the U.S. Federal Food, Drug, and Cosmetic (FD&C) Act that created the designation of “Outsourcing Facility,” a specialized type of compounding pharmacy. These facilities are permitted to compound large batches of sterile and non-sterile drugs without patient-specific prescriptions, primarily for use in hospitals or physician offices. Registration under Section 503B mandates adherence to the rigorous quality standards of Current Good Manufacturing Practice (cGMP), the same regulations governing traditional pharmaceutical manufacturers.
