ICH Guidelines (Quality) For Pharmaceutical Industry

ICH guidelines and its references

International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) is a global initiative that brings together heavy-weight regulatory authorities of Europe, Japan, the USA, and the pharmaceutical industry to prepare guidelines and discuss scientific and technical aspects of pharmaceutical product development and its registration.

The mission of the ICH is to promote public health by achieving greater harmonization through developing technical Guidelines and requirements for pharmaceutical product registration. ICH guidelines topics are divided into four major categories: Quality, Safety, Efficacy, and Multidisciplinary guidelines coded as Q, S, E, and M, respectively. Here in this article, we will list all the Quality guidelines which are the most widely followed in industrial pharmacy.

Following is the list of ICH guidelines for stability testing:
