CD Formulation - Light Stability Analysis

Light stability testing in the pharmaceutical industry is necessary to ensure the potency, efficacy and safety of manufactured products in clinical use. Photostability testing of APIs and products is performed according to ICH Q1B guidelines, and the selection of an appropriate light source is an important consideration for consistent results. Photodegradation of drugs in products is a function of spectral distribution and light source intensity. Therefore, a specific light source needs to be selected for the photostability assessment.
