The International Council for Harmonization (ICH) aims to harmonize technical and legislative requirements for pharmaceuticals across Europe, Japan, and the USA, facilitating the development of safe and effective medicines while reducing research duplications and marketing timeframes. ICH consists of regulatory bodies and industry representatives from these regions and operates through a structured process of guideline development and consensus building among its members. Key topics addressed by ICH include quality, safety, efficacy, and multidisciplinary aspects of pharmaceutical regulations.
