A simple, reliable, rapid, precise, sensitive and validated RP-HPLC method has been developed to determine Acetaminophen (AI) and Prasugrel (PRA) in synthetic mixture form. Chromatographic separation achieved isocratically on Luna C18 column (5 µm, 150mm x 4.60mm) and acetonitrile: 0.05M ammonium acetate buffer (pH 4.5) in the ratio of 75:25 (v/v) as the mobile phase, at a flow rate of 0.6 mL/min. Detection was carried out at 245 nm. Parameters such as linearity, precision, accuracy, recovery, specificity and ruggedness are studied as reported in the ICH guidelines. The retention times for AI and PRA was found to be 2.25 ± 0.5 and 8.72 ± 0.5 min respectively. Linearity for AI and PRA was in the range of 75-375 μg/mL and 10-50 μg/mL respectively.  The mean recoveries obtained for AI and PRA were 99.58 and 99.48% respectively and RSD was less than 2. The correlation coefficients for all components are close to 1. Developed method was found to be accurate, precise, selective and rapid for simultaneous estimation of AI and PRA.
