ABSTRACT

A simple, cost effective and sensitive UV spectrophotometric method has been developed for the simultaneous estimation of Lopinavir (LOPI) and Ritonavir (RITO) in combined tablet dosage form. The method was validated as per ICH guidelines. Ritonavir and lopinavir exhibited maximum absorbance at 240nm and 260nm. Ritonavir obeyed Beer’s law in the concentration range of 10-50μg/mL while Lopinavir obeyed the Beer’s law in the concentration range of 100-500μg/mL. Molar absorptivity of the drugs were determined. The method was developed by using simultaneous equation method. Assay of the tablet were carried out and percentage of Ritonavir present in tablet was found to be 102.93%. The percentage of lopinavir present in tablet was found to be 102.08%. The amount of drug present in the tablet lies within the IP limit.

Keywords: UV Spectrophotometry, Ritonavir, Lopinavir, Simultaneous Equation.
