The Compounding Quality Act established two types of pharmacies: 503A and 503B. What distinguishes these two categories?

• A. 503A compounding in response to individual prescriptions; 503B permitted to compound in bulk
• B. Both 503A and 503B are allowed to compound in bulk
• C. 503A compounds only for hospitals
• D. 503B compounds only for outpatient clinics

Answer: (A)

The core idea is how compounding is regulated based on purpose and scale. 503A pharmacies prepare medications specific to an individual patient and their prescription, focusing on personalized, patient-by-patient compounding rather than large-scale production. 503B facilities, by contrast, are outsourcing facilities that can compound in bulk without a patient-specific prescription, supplying hospitals, clinics, and other facilities and following stricter FDA current good manufacturing practices. So, the best way to distinguish them is that 503A is for patient-specific compounding, while 503B is for bulk, non-prescription outsourcing of sterile products. The other options aren’t accurate because they imply bulk compounding applies to 503A, or that 503B is limited to outpatient clinics or that both categories bulk-compound, which they do not.
