How do Lopinavir and Ritonavir work?

During infection with HIV, the virus multiplies within the body’s cells. Viruses are released from the cells and spread throughout the body where they infect other cells. In this manner, the infection is perpetuated among new cells that the body creates continually. During the production of the viruses, new proteins for the viruses are made. Some of the proteins are a structural protein that forms the body of the viruses. Other proteins are enzymes which manufacture DNA and other components for the new viruses. It is the protease that forms the new structural proteins and enzymes.

Lopinavir and Ritonavir block the action of protease. That it results in the formation of defective viruses that are unable to infect the body’s cell. Therefore, the number of viruses in the body decreases.
