Pharmaceutical Stability Studies as per ICH Guidelines

Stability studies under ICH guidelines are critical to securing product approval, determining shelf‐life, and maintaining brand reputation. At Tamil Nadu Test House, we provide full‐service stability programmes, from long-term testing to photostability, for the Indian pharmaceutical market.

What are Pharmaceutical Stability Studies?

Pharmaceutical stability studies evaluate how a drug substance or finished product maintains its quality under specified temperature, humidity and light conditions. ICH stability testing helps manufacturers establish suitable storage conditions, retest periods and product shelf life using analytical results collected at planned intervals. Tamilnadu Test House provides comprehensive stability studies with controlled chambers, validated analytical testing, and regulatory documentation for pharmaceutical companies across India
