GMP is a set of principles and procedures that ensure products are consistently manufactured and controlled according to quality standards for their intended use. Key aspects of GMP include requirements for facilities, equipment, personnel, documentation, raw materials, production, packaging and labeling, quality control, self-inspection and product recalls. GMP regulations in India were introduced in 1988 and amended in 2001, embracing rules under the Drugs and Cosmetics Rules 1945. Facilities must be designed and maintained to allow production under hygienic conditions in order to prevent contamination and cross-contamination.
