Pharmacy 503B Outsourcing refers to a specific type of pharmaceutical
outsourcing facility regulated under Section 503B of the Federal Food,
Drug, and Cosmetic Act (FDCA). It involves the outsourcing of compounded
medications by a pharmacy facility that is registered with the U.S. Food
and Drug Administration (FDA). These pharmacies are authorized to
produce large quantities of compounded drugs for hospitals, clinics, and
other healthcare providers, primarily for office use and without requiring
individual prescriptions for each patient.
Pharmacy 503B outsourcing provides a crucial role in the healthcare
system by producing bulk compounded medications that are safe,
effective, and in compliance with FDA standards, ensuring that healthcare
providers have the necessary medications to treat their patients in a timely
and cost-effective manner.
Key Components of Pharmacy 503B Outsourcing
1. FDA Registration and Compliance:
A 503B outsourcing facility is required to register with the FDA, adhere to Current Good Manufacturing Practices
(CGMPs), and comply with strict quality control standards. These facilities are distinct from traditional compounding
pharmacies (which are regulated under Section 503A of the FDCA), which only compound drugs for individual patients
based on prescriptions.
Outsourcing facilities are required to follow more stringent manufacturing practices, ensuring that the compounded
drugs meet the same high standards as FDA-approved medications.
2. Compounding Medications for OfÏce Use:
503B outsourcing facilities primarily compound medications in bulk and sell them to healthcare providers, such as
hospitals, surgical centers, and physicians’ offices. These medications are not dispensed directly to patients but are
intended for use in clinical settings.
Common types of compounded medications produced include injectable drugs, sterile preparations (e.g., IV solutions),
and other treatments needed for various medical procedures or patient care.
3. Sterile and Non-Sterile Compounding:
503B outsourcing facilities may compound both sterile and non-sterile medications, though sterile compounding (such
as injectables and IV bags) is often the focus due to its critical role in clinical settings.
They must adhere to USP <797> standards for sterile compounding, ensuring that the drugs are prepared in sterile
environments to prevent contamination.
