Development and Validatin of a Normal Phase HPTLC Method for Simultaneous Estimation of Cetirizine Hydrochloride and Phenylephrine Hydrochloride in Fixed Dose Combination Tablets
Abstract
Abstract:This paper presents the development and validation of a method for the simultaneous analysis of Cetirizine hydrochloride (CTZ) and Phenylephrine hydrochloride (PHE) using high performance thin-layer chromatography (HPTLC) with densitometric detection. Separation was performed on silica gel G 60F254 plates. The mobile phase is comprised of Toluene: Ethyl acetate: Methanol: Ammonia (5:2:3:0.4 v/v/v/v). Detection wavelength was 254 nm. The Rf values were 0.31...
