Accelerated stability testing EXCEPT:

Accelerated stability testing EXCEPT:

• A. Performed at higher temperatures to intensify degradation through time
• B. Done to determine the shelf life of the product in a short period of time
• C. Enough proof of shelf life and need not be further validated
• D. The initial method used to determine a product's shelf life

Answer: (C)

Accelerated stability testing is a technique used to speed up observations of how a product degrades by exposing it to higher temperatures, which increases the rate of chemical and physical changes. This lets you observe degradation trends quickly and estimate shelf life using models that relate temperature to degradation rate. That makes the statements that it’s performed at higher temperatures to accelerate degradation and that it’s done to determine shelf life in a short period true. However, it cannot provide complete, definitive proof of shelf life on its own. Real-time stability data under recommended storage conditions over the intended shelf life are still needed to fully validate shelf life. So the claim that accelerated stability testing gives enough proof and requires no further validation is not correct. Accelerated testing is a powerful supporting tool, but it does not replace real-time validation.
