Development and Validation of UV Spectrophotometric Method of Ambroxol Hydrochloride in Bulk and Pharmaceutical Formulation

Two simple, precise and economical UV methods have been developed for the estimation of Ambroxol Hydrochloride in bulk and pharmaceutical formulations. Ambroxol Hydrochloride has the absorbance maxima at 246.5nm (Method A), and in the first order derivative spectra showed sharp peak at 240 nm (Method B). Linearity for detector response was observed in the concentration range of 10–50 μg/ml for all two methods. The proposed methods were successfully applied for the estimation of Ambroxol Hydrochloride in commercial pharmaceutical preparation by using simple solvent Distilled water. The results of the tablet analysis were validated with respect to accuracy (recovery), linearity, Limit of Detection and Limit of Quantification and specificity were found to be satisfactory.
