Used primarily in the treatment of HIV infection, it functions as an integrase strand transfer inhibitor (INSTI). It works by blocking the integrase enzyme, which is essential for the replication of the HIV virus. This helps to reduce the viral load in the body and maintain a healthy immune system. It is often included in antiretroviral therapy (ART) regimens for both treatment-naive and treatment-experienced patients. Its long-acting formulation allows for less frequent dosing, improving patient adherence to the treatment regimen. It is particularly effective in combination with other antiretroviral agents to achieve sustained virological suppression.
