Ranitidine

Ranitidine hydrochloride tablet is used as a drug of choice for peptic ulcer therapy. It is   available in several brands in the Sudanese pharmaceutical market. The aim of this study was to evaluate the quality, safety and efficacy of the different brands and to assure the interchangeability among different brands and the originator (Zantac®).Four brands available in the market were assessed “evaluated” using pharmacopoeial parameters for quality such as weight variation test, hardness test, friability test, dissolution test and assay along with the similaritydissimilarity factors were evaluated. The results obtained in this study showed that the different brands satisfied pharmacopoeial parameters, although not all of them were pharmaceutically equivalent or interchangeable with the originator. Key words: Ranitidine, Sudanese drug market, quality control, interchangeable.  

  A simple and rapid method has been developed for the quantification of Domperidone (DMP) and Ranitidine (RAN) through FT-IR in combined dosage form. The method involves the measurement of peaks of amine (-NH) at 1620 cm-1 (RAN) and carbonyl group (C=O) at 1717 cm-1 (DMP). The method was validated for pharmaceuticals in tablet form and found to be precise with high recovery levels (>99%). Key words: FT-IR, Ranitidine, Domperidone, combined dosage form.
