When it comes to ICH stability testing, long-term and accelerated stability testing each have unique conditions and storage times. We’ve outlined the conditions and storage duration for each type of ICH stability testing below: Long-term Conditions: +25⁰C, 60%RH Storage duration: 12 months Accelerated Conditions: +40⁰C, 75%RH Storage duration: 6 months As the name implies, accelerated stability testing can produce results in a shorter period of time by simulating long-term conditions.
