Two Different Chromatographic Methods for Simultaneous Determination of Common Cold Drugs Ambroxol Hydrochloride, Pseudoephedrine Hydrochloride, Levoceterizine Dihydrochloride and Desloratadine, in Pure Forms, and in Pharmaceutical Dosage Forms.
Abstract:Two chromatographic methods were developed for simultaneous determination of some drugs used in common cold. First method is TLC-Densitometric method for the simultaneous estimation of Ambroxol hydrochloride (AMB), Pseudoephedrine hydrochloride (PSE) and Desloratadine (DES) in pure form and in pharmaceutical dosage form, the best resolution was obtained by the use of mobile phase (Ethyl acetate: methanol: ammonia), (14: 0.8: 0.5, v/v/v), the scanning of spots was performed at 254 nm in concentration range (1-4… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
