What is Foscarnet?
Plain description, key identifiers and synonyms
Phosphonoformic acid is phosphoric acid in which one of the hydroxy groups is replaced by a carboxylic acid group. It is used as the trisodium salt as an antiviral agent in the treatment of cytomegalovirus retinitis (CMV retinitis, an inflamation of the retina that can lead to blindness) and as an alternative to ganciclovir for AIDS patients who require concurrent antiretroviral therapy but are unable to tolerate ganciclovir due to haematological toxicity. It has a role as a geroprotector, an antiviral drug, a HIV-1 reverse transcriptase inhibitor and a sodium-dependent Pi-transporter inhibitor. It is a member of phosphonic acids, a carboxylic acid and a one-carbon compound. It is functionally related to a formic acid and a phosphonic acid. It is a conjugate acid of a phosphonatoformate and a phosphonoformate(2-).
