54 A globally harmonized GMP normal for medicinal products in concluded dosage sorts like that to the manufacture of active pharmaceutical elements (APIs)—namely the PIC/S Information to GMP for Medicinal Products Aspect II—can do away with these kinds of ambiguity and confusion. This tends to go a long get more info way in enhancing General GMP compliance and high quality assurance while in the pharmaceutical manufacturing sector. It's also consistent with the mission of PIC/S to lead during the Worldwide progress, implementation and maintenance of harmonized GMP benchmarks.
