Used in combination with other antiretroviral agents for the treatment of human immunodeficiency virus type 1 (HIV-1) infection. It functions as an integrase inhibitor, blocking the action of the HIV integrase enzyme, which is essential for viral replication. By inhibiting this enzyme, the virus cannot integrate its genetic material into the host cell DNA, thereby reducing viral load and slowing disease progression. Often included in fixed-dose combination tablets to improve adherence and simplify dosing regimens in patients undergoing long-term HIV therapy.
