Good Manufacturing Practices (GMP) is a system that ensures that goods are consistently produced and monitored in accordance with quality standards. It is intended to lessen any production-related risks for pharmaceuticals that cannot be completely eliminated through testing the finished product. The greatest risks include sudden product contamination, which could result in harm to health or even death, inaccurate labelling on containers, which could result in patients receiving the wrong medication, and insufficient or excessive amounts of the active ingredient, which could result in ineffective treatment or negative side effects.

It supplies Detailed, written procedures area unit needed for every technique that can have an impact on the standard of the end product. GMP covers all parts of production from the initial materials, premises, and equipment to the coaching and private hygiene of employees. Systems should exist to generate written evidence that proper procedures are routinely followed at each stage of the production process each time a product is made. It provides instructions for the manufacture, supervision, storage, and delivery of cosmetic products. These regulations cover the product's quality features, but they do not, as a whole, cover the safety of the plant's employees or environmental protection issues.
