Abstract
Two simple, sensitive, rapid and accurate extractive spectrophotometric methods have been developed for the estimation of promethazine hydrochloride in tablet forms. In first method, absorbance of promethazine hydrochloride-Eriochrome black-T complex was measured at 520 nm (λmax). Second method is based on the formation of promethazine hydrochloride-calcon complex having maximum absorbance at 540 nm. The proposed methods were validated statistically and by recovery studies. The linearity was found to 1.2-10.5 and 2.0-14.0 μg/mL for first and second method, respectively.
