Everything about Cidofovir totally explained
Cidofovir is an injectable
antiviral medication for the treatment of
cytomegalovirus (CMV)
retinitis in patients with
AIDS. It suppresses CMV replication by selective inhibition of viral DNA synthesis. It is an
acyclic nucleoside phosphonate, and is therefore independent of phosphorylation by viral enzymes, in contrast to, for instance,
acyclovir.
Administration
Maintenance therapy with cidofovir involves an infusion only once every two weeks, making it a convenient treatment option. Because dosing is relatively infrequent, a permanent catheter isn't necessary for infusions.
Side effects
The major side effect of cidofovir is that it can be
nephrotoxic.
Uses
Cidofovir demonstrated a statistically significant effect in delaying the progression of CMV retinitis lesions in newly diagnosed patients, as well as in previously treated patients who had failed other therapies.
Cidofovir has also shown efficacy in the treatment of
acyclovir resistant
herpes
Cidofovir has also been investigated as a treatment for
progressive multifocal leukoencephalopathy, but
as of 2005 studies are inconclusive.
Cidofovir might have anti-
smallpox efficacy and might be used on a limited basis in the event of a
bioterror incident involving smallpox cases.
Cidofovir shows anti-
BK virus activity in a subgroup of transplant patients.
Cidofovir is being investigated as a complementary intralesional therapy during laryngo- and bronchoscopic excision of papillomatosis caused by HPV.
History
Cidofovir was discovered at the Institute of Organic Chemistry and Biochemistry, Prague, by
Antonín Holý, and developed by
Gilead Sciences and is marketed with the brand name
Vistide by Gilead in the USA, and by
Pfizer elsewhere.
