Manufacturing - Therapeutics/Pharmaceuticals


Manufacturing broadly refers to the general production of a medical product. While the process varies among pharmaceuticals/drugs, medical devices, and biologics/biosimilars, there are shared manufacturing principles and practices followed by manufacturers across all medical product types. In Figures 1, 2, and 3, you can see batch, continuous, and biological manufacturing processes, respectively. For information on devices, visit the Manufacturing Devices section.

Manufacturers must comply with Current Good Manufacturing Practices (CGMP), which refers to the regulations set forth by the FDA to ensure the “proper design, monitoring, and control of manufacturing processes and facilities” of medical products. These regulations outline production standards and include the minimum requirements for the methods, facilities, and controls used in the manufacturing, processing, and packaging of medical products. The FDA enforces CGMP compliance through surveillance inspections of manufacturing facilities to evaluate their compliance to CGMP as well as application-based inspections as part of a marketing application filed with the FDA. Note that it is more challenging to test the safety and potency of a biologics’ final products. Unlike traditional drug products composed of pure chemical substances, biologics derive their starting material from living systems. Because of this, the FDA monitors the manufacturing of biologics from its early stages paying close attention to any changes to the process, equipment, or facility that can affect the product.

Additionally, the FDA requires registration of domestic and foreign companies (or establishments) that manufacture, repack, or re-label drug and biologic products, including vaccines, and devices marketed in the United States. These companies are also required to provide a thorough inventory of all their commercially distributed products.
