Aim of the present work was to develop simple, shorter and effective HPLC method with UV detection (240 nm) and subsequent validation for forced degradation studies of lopinavir using RP-HPLC and characterization of degradants by LC-MS/MS. The method uses isocratic the mobile phase mixture of buffer and acetonitrile taken in the ratio in the ratio of 45:55 (v/v) on Hypersil BDS, C18, 100 x 4.6 mm, 5 μm column. The RSD for five injections was observed to 1.1 percentage and linearity range of 25-150 percentage of label claim established with 0.999 correlation. The observed result shows that the method was rapid, precise, accurate and simple. The method was validated as per ICH guidelines.
