Abacavir is an antiretroviral medication used in the treatment of Human Immunodeficiency Virus (HIV) infection. It belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors (NRTIs). Abacavir works by inhibiting the action of reverse transcriptase, an enzyme critical for the replication of HIV. This helps to reduce the viral load in the body and improve the function of the immune system.
