Abstract:This study involves the development of two sensitive and reproducible spectrophotometric methods to determine oxymetazoline- HCl in pure form and its dosage forms. Both spectro-photometric methods were based on the reduction of potassium permanganate with oxymet-azoline- HCl.In method (A), oxymetazoline-HCl was reacted with an excess known amount of potassium permanganate in an acid solution of H2SO4 and the absorbance of unreacted potassium per-manganate was measured at 545 nm. In method (B) the oxidation rea… Show more
