 infections in immunocompromised patients.
 | 
| 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.
 | 
| Mechanism_of_action: | Foscarnet exerts its antiviral activity by a selective inhibition at the pyrophosphate binding site on virus-specific DNA polymerases at concentrations that
 do not affect cellular DNA polymerases.
