The Drugs and Cosmetics Act (DCA) 1940 and Rules 1945 - Forensic Pharmacy - Schedule M - GMP (Good Manufacturing Practices) and Requirements of Premises, Plant and Equipment


Schedule M

GMP (Good Manufacturing Practices) and Requirements of Premises, Plant and Equipment

In order to ensure production of quality drug formulation, it is necessary on the part of the manufacturer to follow well established and ethical approach involving different operations of manufacture. It was on several occasions discussed in professional meetings and conferences that there is a need for well set mandatary guidelines required to be followed by manufactures of different dosage formulations. It was with this background, Good Manufacturing Practices under Schedule M were made m~ndatory conditions for manufacturing operations of pharmaceutical formulations.

The quality of drug formulations is the sole responsibility of the manufacturer. He has to ensure the production of desired quality formulations and their stability until, the formulation reaches the consumer across the retailing counter. The Schedule M is covered under Rules 71, 74, 76 and 78 and is in two parts.

Part I deals with GMP relating to factory premises and materials.

Part II deals with requirement of plant and equipment.
