GMP requirements for 5 tablet workshops (including plant, equipment, personnel, production and quality management)

Hey! I finally find the Answer!

This article focuses on 5 different aspects of GMP requirements for tablet shops.

The main contents of GMP are suitable to plant facilities, good technical equipment, and storage, and transportation conditions, trained and qualified staff, qualified raw and auxiliary materials, verified production methods in a hygienic environment, reliable quality control, and production of high-quality products.

According to the general requirements of GMP, the implementation of GMP in tablet workshops mainly includes 5 aspects: plant, equipment, personnel, production management, and quality management.
