Used in the treatment of HIV-1 infection as part of antiretroviral therapy. It works by inhibiting the integrase enzyme, which is essential for viral replication, preventing the virus from inserting its genetic material into human DNA. This action helps reduce the amount of virus in the body and supports immune system recovery. Commonly prescribed in combination with other antiretroviral drugs to improve efficacy and reduce the risk of drug resistance. Suitable for adult and pediatric patients, including treatment-experienced individuals.
