Why do we need stability testing?

The purpose of stability testing is to provide evidence on how the quality of a drug substance or drug product varies with time under the influence of a variety of environmental factors such as temperature, humidity, and light, and to establish a re-test period for the drug substance or a shelf life for the drug

WHO guidelines for stability testing is for?

What is accelerated stability testing and why is it deemed necessary?

1. Main aim of accelerated stability study to predict the stability profile of a drug product that prediction of self life of the product before launching into market. 3. Prediction of shelf life, which is the time a product will remain satisfactory when stored under expected or directed storage condition.

When should you start a stability study?

Stability studies typically start at the preclinical stage of drug development before an Investigational New Drug (IND) or the Investigational Medicinal Product Dossier (IMPD) has been filed, and usually continue through Phase 1, Phase 2 and Phase 3 to gain further understanding of the product, to support formulation
