Ciclopirox belongs to a class of anti fungal. It is used to treat skin infections caused by fungus, such as ringworm, athlete’s foot or dandruff. The method is based on the oxidation reduction reaction involving the formation of a green colored complex between ciclopirox and ammonium molybdate in the presence of 2M HCl giving absorption maxima at 677 nm. The linearity was found in the concentration range of 10-50 µg/ml. the correlation coefficient was found 0.999. The regression equation was found as Y=0.016x+0.010. The method has been validated as per ICH guidelines.
