Lamivudine is a nucleotide-based reverse transcriptase inhibitor used to treat HIV/AIDS and hepatitis B virus. It is an analog of zalcitabine that competes, in the triphosphate form, for incorporation in viral DNA with cytosine triphosphate. Lacking a 3'-OH group, it terminates DNA chain elongation because the phosphodiester bond necessary for elongation cannot be made.

Its IUPAC name is 4-amino-1-[(2R,5S)-2-(hydroxymethyl)-1,3-oxathiolan-5-yl]pyrimidin-2-one and it has chemical formula C₈H₁₁N₃O₃S, giving it a molecular mass of 229.2562 g/mol.
