  • Abstract

    A simple, rapid, sensitive and reproducible visible spectrophotometric method has been developed for the determination of Alfuzosin hydrochloride (AFZ) in bulk and in its dosage forms. The method is based on the reaction of AFZ with gold (III) chloride in the pH range 1.0 – 5.0 forming red color complex solution, showing absorption maxima at 510 nm. The linear plot indicates that Beer’s law is obeyed in the range of 10 – 110 μg/ml of alfuzosin hydrochloride. The molar absorptivity and Sandell’s sensitivity are 5.62 x 103 l mol-1 cm-1 and 0.0758 μg/cm2 respectively. The standard deviation of the method for ten determinations of 20 μg/ml of alfuzosin hydrochloride is 0.0123. The correlation coefficient (g) of the experimental data of the calibration plot is 0.9991. The effective range of concentration for accurate determination of alfuzosin hydrochloride as ascertained from Ringbom’s plot and it is 20 – 100 μg/ml. Interferences of the other ingredients and excipients were not observed. The optimum reaction conditions and other analytical parameters were evaluated. The methods were successfully applied to the determination of AFZ in pharmaceutical formulations.
