503A vs. 503B Compounding Pharmacies

At PharmaCorr Sterile, we offer both 503A and 503B compounding services to meet the diverse needs of healthcare providers and their patients. Understanding the differences between these two designations will help you select the right compounding service for your needs.

What is a 503A Compounding Pharmacy?

A 503A compounding pharmacy is designed to create customized medications for individual patients based on a valid prescription from a licensed prescriber. These compounds are patient-specific and are made to order in compliance with the United States Pharmacopeia (USP) guidelines, following state pharmacy laws. 503A compounding pharmacies cannot produce medications in bulk; they are strictly intended to meet the immediate needs of individual patients.

Key Features of 503A Compounding:
  • Medications are made per individual prescription.
  • Adheres to USP <795>, <797>, and <800> standards for non-sterile and sterile compounding.
  • State-regulated, and FDA oversight is limited to ensuring compliance with USP guidelines.
  • Typically used for patients requiring specific formulations that are not commercially available.

What is a 503B Compounding Pharmacy?

A 503B compounding pharmacy operates as an outsourcing facility and can produce medications in larger quantities for healthcare providers and institutions. These pharmacies are FDA-registered and must comply with current Good Manufacturing Practices (cGMP), which are the same standards applied to large-scale drug manufacturers. 503B pharmacies are allowed to compound drugs in bulk, making them ideal for hospitals, clinics, and healthcare facilities needing office-use medications that don’t require patient-specific prescriptions.

Key Features of 503A Compounding:
  • Can produce medications in bulk for office-use and distribute across state lines.
  • Must comply with FDA cGMP regulations, ensuring the highest standards of quality and safety.
  • Regular FDA inspections and strict regulatory oversight.
  • Suitable for healthcare facilities requiring large quantities of compounded medications without patient-specific prescriptions.
