Robert T. Magari, Ph. In accelerated stability tests, a product is stored at elevated stress conditions (such as temperature, humidity, and pH). Degradation at the recommended storage conditions can be predicted using known relationships between the acceleration factor and the degradation rate.

How do you calculate retest period?

Retest period: The period of time during which the drug substance is expected to remain within its specification and, therefore, can be used in the manufacture of a given drug product, provided that the drug substance has been stored under the defined conditions.

What are ICH guidelines?

ICH Guidelines were created by The International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH). ICH aims to provide uniform standards for technical requirements for pharmaceuticals for human use. They are developed by regulatory and pharma industry authorities.
