Used in the treatment of HIV-1 infection as part of antiretroviral therapy. It works by inhibiting the integrase enzyme, which is essential for inserting viral DNA into the human genome. By blocking this step, the drug prevents the virus from replicating and reduces viral load in patients. It is typically prescribed in combination with other antiretroviral agents to improve efficacy and reduce the risk of drug resistance. Suitable for adult and pediatric patients, including treatment-experienced individuals with resistant virus strains.
