Raltegravir is an antiretroviral medication used to treat HIV infection. It belongs to a class of drugs called integrase inhibitors, which work by blocking the virus's ability to integrate its genetic material into the host's DNA. This helps to reduce the amount of virus in the body, allowing the immune system to recover and function more effectively. Typically taken as a tablet, Raltegravir is often prescribed in combination with other antiretroviral medications to enhance its effectiveness. It is important for patients to adhere to their prescribed treatment regimen to maintain viral suppression and improve their overall health.
