Dolutegravir is an antiretroviral medication used to treat HIV (Human Immunodeficiency Virus). 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 reduce the viral load in the body, allowing the immune system to recover and function more effectively. Approved for use in various treatment regimens, Dolutegravir is often combined with other medications to enhance its effectiveness. It is known for its favorable safety profile and is typically taken once daily, making it a convenient option for many patients managing HIV.
