RESULTS AND DISCUSSION Preformulation Studies The melting point of Metoprolol Tartrate was determined by capillary method and was found to be 121ºC (120 - 124ºC) as reported in literature, thus indicating purity of Metoprolol Tartrate. FTIR analysis showed that all the characteristic peaks of Metoprolol Tartrate and mixture of Metoprolol Tartrate with excipients were present in the range of reported frequencies; which shows that drug and excipients were compatible with each other. DSC thermogram of Metoprolol Tartrate alone showed endothermic peak at 120.73°C, corresponding to the melting point of the drug. The thermal curve of the Metoprolol Tartrate obtained indicated its crystalline anhydrous state, exhibiting a sharp endothermic peak at 120.73°C. The…show more content…
