Why accelerated stability test is carried out up to six months only?

Accelerated stability tests are typically conducted for up to six months to quickly assess the shelf life and stability of a product under exaggerated stress conditions, such as higher temperatures and humidity. This duration allows for the observation of potential degradation trends without the need for extended timeframes, which can be impractical for product development. The six-month period is often sufficient to predict long-term stability and inform formulation adjustments, while regulatory guidelines often support this timeframe for initial stability assessments. Additionally, results from these tests can help identify potential issues early in the development process, facilitating timely interventions.
