Derivative spectroscopy offers a useful approach for the analysis of drugs in multi-component mixtures. In this study a first-derivative spectroscopic method was used for the simultaneous determination of diclofenac and pantoprazole in combined capsule dosage form using the zero-crossing technique. The wavelengths 290.2 nm and 276.2 nm of first derivative spectrum were selected for the estimation of diclofenac and pantoprazole, respectively without mutual interference. The method was linear in the concentration range 15-75μg/ml and 5-25μg/ml for diclofenac and pantoprazole, respectively. Validation studies confirmed the accuracy and precision of the proposed method. The result of the formulation analysis shows that the proposed method can be successfully used for the simultaneous estimation of both the drugs in their combined capsule dosage form.
