Ritonavir + Lopinavir

Introduction

Ritonavir + Lopinavir is a fixed-dose combination medication used primarily in the treatment of HIV (Human Immunodeficiency Virus) infection. Both are antiretroviral drugs that belong to the class of protease inhibitors. Lopinavir works by inhibiting the activity of the HIV protease enzyme, preventing the virus from multiplying, while Ritonavir enhances the effectiveness of Lopinavir by slowing its breakdown in the body. This combination helps reduce the viral load in the blood, improve immune function, and delay the progression of HIV-related complications.

This boosts the effectiveness and duration of Lopinavir’s action.
