Abacavir is an antiviral drug to treat HIV infection. The use of this drug should be accompanied by other anti- HIV drugs to maximize their effectiveness. Abacavir cannot cure HIV, but only slows the progression of HIV infection.
Abacavir works by inhibiting the process of replication or reproduction of the HIV virus, so that the amount of HIV virus in the blood decreases. This way of working can improve the immune system of people with HIV and reduce the risk of complications and diseases associated with HIV/AIDS infection, such as Kaposi's sarcoma or cancer.
