What is the Origin of Quality Control in Pharmacies?

The concept of quality control is rooted in industrial manufacturing but was formally applied to pharmacy and drug production following regulatory acts in the mid-twentieth century aimed at ensuring drug safety and efficacy. For compounding pharmacies, the term gained specific regulatory emphasis to ensure the safety of individualized preparations not covered by large-scale pharmaceutical manufacturing standards. It is a legal and ethical imperative in the healthcare system.

What is the Mechanism of Quality Control in Pharmacies?

The mechanism of QC involves a multi-step verification process, starting with the qualification of suppliers and the analytical testing of every active pharmaceutical ingredient for purity and concentration. Next, compounding procedures are validated to ensure uniformity and sterility, especially for injectable or sterile preparations. Finally, the finished product undergoes a check, often including high-performance liquid chromatography (HPLC) testing for potency and stability, before it is released to the patient, thereby minimizing the risk of sub-potent or contaminated medication.

Quality Control in Pharmacies

Meaning

Quality Control (QC) in pharmacies is a systematic set of processes and procedures designed to ensure that compounded or dispensed medications consistently meet predetermined standards for identity, strength, quality, and purity. This includes rigorous testing of raw materials, validation of compounding techniques, verification of final product dosage accuracy, and strict adherence to Good Compounding Practices (GCP) or Good Manufacturing Practices (GMP). Effective QC is paramount for patient safety and therapeutic efficacy.
