A simple and sensitive extractive spectrophotometric method have been developed and validated for determination of amantadine hydrochloride (AM), memantine hydrochloride (MM) and rimantadine hydrochloride (RM) in pure and pharmaceutical formulations. The method is based on the reaction of these active compounds with bromophenol blue (BB) in acetate buffer (0.1 M) pH 3.5 to form an orange-colored products which have absorption maxima at 408 nm. The procedure of complexation was optimized with… Expand
A simple and rapid microplate fluorescence determination of adamantanes in pharmaceutical formulations
Abstract Adamantane drugs (e.g., memantine, rimantadine, and amantadine) consist of a core tricyclodecane with different substituents. Memantine is used for treatment of Alzheimer’s disease, whileExpand
