Abstract
A simple UV-Vis Spectrophometric method was developed for the simultaneous determination of salbutamol sulphate and ambroxol HCl (AMB) from their combined dosage form. The method employs formation and solving of simultaneous equation using 242 nm and 272 nm as two analytical wavelengths (λ<sub>Max</sub> of the drugs) of detection. Both the drugs obeyed Beer-Lambert’s law over the concentration range 1-50 μg/mL for salbutamol sulphate and 10-50 μg/mL for ambroxol HCl, respectively. The developed method was validated for Accuracy, Precision, Limit of Detection and Limit of Quantification as per ICH guidelines and results of analysis were validated statistically.
