Abacavir Sulphate tablets are a prescription antiviral medication used in combination with other drugs to treat HIV-1 infection, working as a nucleoside reverse transcriptase inhibitor (NRTI) to stop the virus from replicating, reducing viral load, and improving immune function, but they don't cure HIV and require daily adherence; important considerations include potential severe hypersensitivity reactions, necessitating screening, and that it's often combined with Lamivudine (3TC) for better efficacy, available in various strengths for adults and older children. 

How it works

• It's a guanosine analog that gets converted into its active form, blocking the HIV reverse transcriptase enzyme, which is essential for the virus to make copies of itself. 

Uses

• Treats HIV-1 infection as part of a combination antiretroviral therapy (ART).

• Helps control the virus, boost CD4+ T-cells, and reduce the risk of opportunistic infections and death.
