Abstract

An Accurate, Precise, Rugged, Reproducible Reverse Phase High Pressure Liquid Chromatographic (RP-HPLC) method has been developed and validated for the simultaneous estimation of Lopinavir and Ritonavir in pharmaceutical dosage form of anti-retroviral protease inhibitor class of compounds. The method was achieved by using the mixed organic mobile phases of Acetonitrile: Methanol with the buffer of potassium dihydrogen phosphate (pH 3.5) and Xbridge C18 (250 mm × 4.6 mm i.d., 3.5 μm. The flow rate was set as 1.1 ml/min has provided a good peak shape of Ritonavir and Lopinavir were found well separated at 5.7 and 6.6 min respectively.

Keywords:

Lopinavir; Ritonavir; Xbridge C18
