A novel simple, accurate, precise and selective high performance liquid chromatographic (HPLC) method was developed and validated for simultaneous estimation of Ritonavir and Lopinavir in tablet dosage form. An isocratic, reverse phase HPLC method was developed and validated using Hypersil C18 (250 mm×4.6 mm i.d.) 5μm, column and orthophosphoric acid pH3 and methanol (40:60) as mobile phase and detection is carried out at a wavelength of 273nm.The retention time for RITO and LOPI were 3.3±0.1 min and 4.7±0.1min respectively. The method was validated with respect to linearity, precision, accuracy and robustness.
