ICH Guidelines for Pharmaceuticals (Human use)
ICH stands for International Conference on Hormonisation. It provides Technical requirements for registration of Pharmaceuticals (Human use). ICH is a committee of three regulatory bodies Europe, Japan and United State also known as Tripartite Guideline. Several Countries have been adopted ICH guideline as law but USFDA (United State Food and drug Administration) used as guidance.
