A titration in nonaqueous medium was proposed to determine simultaneously the mixtures of Chlorpheniramine maleat and the other halogen salts (Dextromethorphan HBr and phenylpropanilamin HCl). The first one was assayed for having the equivalent point EP1. For the second halogen salts we added (CH3COO)2 for liberating halogen radicaux and trans forming to base form. This form was recorded the equivalent point EP2.
