Two senstive methods for the determination of diethylcarbamazine citrate, bephenium hydroxynapthoate, tetramisole hydrochloride and levamisole hydrochloride based on the formation of coloured complexes of the drug with reagents such as fast green FCF at pH 5.0 or orange-II in presence of O.IN HCI are described in bulk samples and pharmaceutical preparations. The ion-pair complexes foemed are quantitatively extracted into chloroform under the experimental conditions.
