title: [Visible spectrophotometric assay of ranitidine].
abstract: Ranitidine, belonging to H2-antagonist group, is a compound containing a furanic moiety and is used in peptic ulcer therapy. This paper debates the possibility of developing a new visible spectrophotometric assessment by using the reaction between ranitidine and eosine. We carried out our determinations at 505 nm, where the absorbency of ranitidine-eosine complex is maximal, and we have established the optimal reaction conditions. This method was successfully applied for ranitidine assay from pharmaceutical dosage forms.
