Cidofovir (CDV) is an antiviral drug used to treat herpes cytomegalovirus (CMV) retinitis associated with HIV/AIDS. It is an analog of the natural nucleoside cytosine used in DNA. It selectively inhibits the CMV DNA polymerase, probably as the diphosphate, at concentrations 8- to 600-fold lower than needed to inhibit human DNA polymerases. Once incorporated into the growing viral DNA chain, the rate of DNA chain synthesis is reduced. Kidney damage and reduced levels of white blood cells and platelets may occur when using this drug. Warning:Acute renal failure requiring dialysis and/or contributing to death have occurred with as few as one or two doses of cidofovir.


Its chemical name is [(2S)-1-(4-amino-2-oxopyrimidin-1-yl)-3-hydroxypropan-2-yl]oxymethylphosphonic acid and its chemical formula is C8H14N3O6P. It is sold under the brand names HPMPC and Vistide.
