What is GMP?

Good Manufacturing Practice (GMP) encompasses the regulations, guidelines, and practices that ensure pharmaceutical products are consistently manufactured to meet quality requirements. In the US, current GMP (cGMP) regulations are codified in 21 CFR Parts 210 and 211 for drugs, and Part 820 for medical devices.

GMP covers all aspects of production including facilities, equipment, personnel training, documentation, production controls, quality control testing, and complaint handling. The "current" in cGMP emphasizes that systems must be kept up-to-date with technological advances and regulatory expectations.

Compliance with GMP is verified through regulatory inspections, and violations can result in warning letters, consent decrees, import alerts, or criminal prosecution.

Regulatory Context

This term appears most often in cmc & manufacturing workflows where submission quality, regulatory evidence, and audit readiness depend on consistent language. It is commonly referenced alongside 21 CFR 210, 21 CFR 211, 21 CFR 820.
