摘要：
This study related to development of rapid, simple, sensitive and cost effective electrochemical and spectrophotometric methods for quantitative determination of silodosin (SLD) in pharmaceutical formulations. The electrochemical oxidation of SLD on glassy carbon electrode (GCE) was thorougly investigated by cyclic voltammetry and differential pulse voltammetry. The effect of scan rate, pH and concentration on the peak currents were investigated under the optimized experimental conditions for quantitative determination of SLD. The oxidation peak of SLD was observed on GCE at 696.0 mV in pH 2.0 BRT by using differential pulse voltammetry. The oxidation process was observed to be irreversible and diffusion-controlled. The obtained results were statistically compared with those of first derivative UV spectrophotometric method and the differences were found as insignificant.
