Abstract
Three simple, accurate and rapid methods have been developed for the assay of two antihistamines, embramine and hydroxyzine hydrochlorides in pure sample and in pharmaceutical preparations. The methods depend on the titration of the chloride content of the drugs with silver nitrate, with visual, potentiometric and conductometric end-point detection.
