What does it do?

• Lopinavir and ritonavir are antiretroviral drugs from the same class, combined together as a single drug, and used in the treatment of HIV infection
• The combination drug is prescribed with other antiretroviral drugs from different classes
• Together these drugs slow down the production of the virus and reduce the damage done to the immune system
• Antiretroviral therapy is not a cure for HIV, but if taken regularly on a long-term basis, it can reduce the amount of virus in the body and improve your general outcome
• The patient will remain infectious, and will suffer a relapse if the treatment is stopped

Lopinavir and ritonavir are both protease Inhibitors - they interfere with an enzyme used by the virus to produce genetic material.
