Indian drugsSummary: Highly resolved and validated Liquid Chromatography method was developed for the separation and quantification of fosamprenavir and its related impurity 2 and 5 in bulk and pharmaceutical formulations. Separation of fosamprenavir and its impurities was achieved on prontosil ODS C18 column using mobile phase composition of methanol and 0.1 m sodium acetate in the ratio of 40:60 (v/v) at pH 5.9 as mobile phase at a flow rate of 0.9 mL/min in isocratic condition. Uv detection of the eluents was monitored at a wavelength of 246nm. In these conditions, well resolved peaks were observed at a retention time of 8.67, 5.73 and 4.00 min for fosamprenavir, Impurity 2 and 5, respectively. Calibration curve was plotted in the concentration range of 75-450 µg/mL for fosamprenavir and 1-6 µg/mL for impurity 2 and 5. Forced degradation study confirms that the method can separate the known and unknown impurities of fosamprenavir and the % degradation was found to be very less in all the stress conditions. Hence the method is suitable for the identification and quantification of impurities 2 and 5 along with fosamprenavir in bulk drug and formulations.
