This study investigated the chemical stability of cannabidiol (CBD) in solid powder and oil solution forms, finding that CBD powder was significantly more stable compared to CBD in oil solution. This finding has important implications for the practical administration of CBD dissolved in oil matrices, highlighting the significance of understanding the acceptable shelf life for CBD products.
Stability studies represent an essential component of pharmaceutical development, enabling critical evaluation of the therapeutic potential of an active pharmaceutical ingredient (API) or a final pharmaceutical product under the influence of various environmental factors. The aim of the present study was to investigate the chemical stability of cannabidiol (CBD) in the form of a solid powder (hereinafter referred to as CBD powder) and also dissolved in sunflower oil. We performed stress studies in accordance with the International Conference on Harmonization (ICH) guidelines, where 5 mg of marketed CBD in the form of a solid powder and in form of oil solution were exposed for 7 and 14, 30, 60, 90, 180, 270, and 365 days to precisely defined temperature and humidity conditions, 25 degrees C +/- 2 degrees C/60% RH +/- 5% and 40 degrees C +/- 2 degrees C/75% RH +/- 5% in both open and closed vials in the dark. CBD powder was significantly more stable than CBD in oil solution. Such finding is important because CBD is often administered dissolved in oil matrix in practice due to very good bioavailability. Thus, the knowledge on admissible shelf time is of paramount importance.
