Abstract
A simple and precise RP-HPLC method has been developed and validated for the estimation of sarpogrelate hydrochloride, an anti-platelet drug in bulk and pharmaceutical dosage forms. Sarpogrelate is an antagonist at 5HT2A and 5HT2B receptors which blocks serotonin induced platelet aggregation and has application in the treatment of diseases including diabetes mellitus, Raynaud’s disease, angina pectoris and atherosclerosis. Chromatography was carried out on a Phenomenex C18 (250 x 4.6mm, 5μm) column with a mobile phase of 10mM ammonium acetate and acetonitrile (45:55% v/v). The flow rate was 1.2mL/min. The detection wavelength was carried out at 220nm. The retention time is 3.356 minutes for sarpogrelate hydrochloride. The linearity was found in the range of 10-50 μg/ml (R = 0.999) and % RSD is less than 2%. The mean recoveries obtained for sarpogrelate hydrochloride were in the range of 98.73-100.67%. The method is validated as per ICH guidelines and can be applied for the estimation of percentage purity in Sarpogrelate hydrochloride for quality control analysis in bulk and its dosage forms.
