Which statement best describes Current Good Manufacturing Practice (cGMP)?

• A. It governs only labeling of drugs
• B. It applies to clinical trials
• C. It is optional for pharmaceutical manufacturing
• D. It requires calibration and validation in manufacturing

Answer: (C)

Current Good Manufacturing Practice establishes mandatory requirements to ensure drug products are consistently produced and meet quality standards. It covers the entire manufacturing lifecycle, including facilities, equipment, personnel, documentation, process control, and quality systems. Because of this, describing cGMP as optional is not accurate and noncompliance can lead to enforcement actions. A central element of cGMP is calibration and validation in manufacturing: calibration ensures measuring instruments are accurate, and validation proves that manufacturing processes consistently produce products that meet predefined specifications. This focus on validated, reproducible processes is what helps ensure product safety and quality from batch to batch. Statements that cGMP only governs labeling or that it applies to clinical trials alone miss the broader scope of the manufacturing and control framework that cGMP encompasses.
