Our discussion focuses on introducing some of the most significant international pharmaceutical and medical device regulations. EU Annex 1 and EU-GMP guidelines focuses on sterile medicinal product manufacturing within the European Union. Chinese Pharmacopoeia (ChP), United States Pharmacopeia (USP), and European Pharmacopoeia (EuPh) establish quality standards for pharmaceuticals across their respective regions, with increasing harmonisation efforts. Finally, the US FDA Quality Management System Regulation (QMSR) outlines quality standards for medical device manufacturers, aligning with international ISO 13485 standards. These regulations impact numerous industries, emphasising quality, risk management, and compliance to protect public health and facilitate global trade.
