ICH Stability Studies of Pharmaceutical Products: A Comprehensive Review

Sunny Kapoorchand Nagwe^1*, Ms. Kulkarni¹

Abstract

Stability testing is a critical quality attribute in pharmaceutical product development, ensuring that drug substances and drug products maintain their safety, efficacy, and quality throughout their shelf life. The International Council for Harmonisation (ICH) has established globally accepted guidelines under the Q1 series to harmonize stability testing requirements across different regulatory regions. These guidelines provide a scientific framework for evaluating the impact of environmental factors such as temperature, humidity, and light on pharmaceutical products. ICH stability studies involve long-term, accelerated, intermediate, photostability, and stress testing to identify degradation pathways and establish appropriate storage conditions and expiry dates. The data generated from these studies support regulatory submissions, ensure patient safety, and facilitate global drug approval. This review provides a comprehensive overview of ICH stability studies, including their importance, objectives, guidelines, testing protocols, and regulatory significance in modern pharmaceutical development.
