Phosphonoformate Indication

Phosphonoformate Pharmacology

Foscarnet is an organic analogue of inorganic pyrophosphate that inhibits replication of herpes viruses in vitro including cytomegalovirus (CMV) and herpes simplex virus types 1 and 2 (HSV-1 and HSV-2). Foscarnet does not require activation (phosphorylation) by thymidine kinase or other kinases and therefore is active in vitro against HSV TK deficient mutants and CMV UL97 mutants. Thus, HSV strains resistant to acyclovir or CMV strains resistant to ganciclovir may be sensitive to foscarnet. However, acyclovir or ganciclovir resistant mutants with alterations in the viral DNA polymerase may be resistant to foscarnet and may not respond to therapy with foscarnet. The combination of foscarnet and ganciclovir has been shown to have enhanced activity in vitro.

Phosphonoformate Absorption

Poorly absorbed after oral administration (bioavailability from 12 to 22%).
