Spectrophotometric determination of mosapride in pure and pharmaceutical preparations

Main Article Content
Abstract
mosapride in pure and in pharmaceutical preparations are described. These methods are based on the
interaction of diazotized mosapride (MSP) couples with chromotropic acid (CTA) [M 1 ] in alkaline
medium and diphenylamine (DPA) [M 2 ] in acidic medium. The resulting azo-dyes exhibit maximum
absorption at 560 nm and at 540 nm for methods M 1 and M 2 , respectively. All variables were studied
in order to optimize the reaction conditions. No interferences were observed from excipients, and the
validity of the each method was tested against reference method.
