The study has successfully achieved development of cheaper spectrophotometric method for quantitative determination of Betamethasone 17-valerate as the method demonstrated high efficiency and accuracy with acceptable percentage recovery and the lowest possible percentage error. This method facilitates production of high quality grade Betamethasone17valerate containing pharmaceutical products by performing post-production quality control analysis which is tasked to ensure that the products meet the required standard. Therefore, the method can be used for routine analysis of betamethasone and hydrocortisone in pharmaceutical formulation.
