Does ganciclovir cover VZV?
Ganciclovir has activity against CMV, HSV, VZV, and HHV-6, HHV-7, and HHV-8. However, one of the other nucleoside analogues (eg, famciclovir, penciclovir, acyclovir) is preferred to treat VZV and herpes simplex infections.
Does ganciclovir treat herpes?
Ganciclovir, foscarnet, and cidofovir are antiviral drugs approved for use against cytomegalovirus (CMV) in adults by the US Food and Drug Administration. They have a broad spectrum of antiviral activity and are accordingly used for treatment of other viral infections, including herpes simplex viruses.
How do you administer ganciclovir?
Caution: Ganciclovir must be administered by intravenous infusion over 1 hour at a concentration not exceeding 10 mg/mL. Do not administer by rapid or bolus intravenous injection because the resulting excessive plasma levels may increase the toxicity of ganciclovir.
How do you dilute ganciclovir?
Reconstitute vial with 10 ml of Sterile Water for Injection (do not use bacteriostatic water), and shake well to dissolve drug. Vial stability: stable at room temperature for 12 hours (Do not refrigerate). Remember when further diluted with NS or D5W, final solution should be refrigerated until ready for use.
In which condition ganciclovir is preferred over acyclovir?
Ganciclovir 0.15% gel is the most recently approved topical treatment for herpes keratitis. Compared to acyclovir 0.3% ointment, ganciclovir 0.15% gel has been shown to be better tolerated and no less effective in several Phase II and III trials.
How long should you take antivirals for herpes?
The tablets, capsules, and suspension are usually taken with or without food two to five times a day for 5 to 10 days, starting as soon as possible after your symptoms begin. When acyclovir is used to prevent outbreaks of genital herpes, it is usually taken two to five times a day for up to 12 months.
Which antiviral drug is best for herpes?
Acyclovir is the antiviral most commonly used to treat herpes simplex virus (HSV) infections. Other oral medications include famciclovir, which is a prodrug that is converted to penciclovir, and valacyclovir, which is a prodrug that is converted to acyclovir.
How long does it take ganciclovir to work?
This usually happens within 1 to 2 weeks of starting treatment.
Should ganciclovir be taken with food?
It is important that you take ganciclovir capsules with food. This is to make sure the medicine is fully absorbed into the body and will work properly. To get the best results, ganciclovir must be given for the full time of treatment. Also, this medicine works best when there is a constant amount in the blood.
What is the difference between acyclovir and ganciclovir?
Ganciclovir is a nucleoside analog that differs from acyclovir by a single carboxyl side chain. This structural change confers approximately 50 times greater activity than acyclovir against CMV. Acyclovir has low activity against CMV because it is not well phosphorylated in CMV-infected cells.
Is ganciclovir same as acyclovir?
Ganciclovir (Cytovene) is a nucleoside analogue that is different from acyclovir by having an extra hydroxymethyl group on the acyclic side chain. Its greatest in vitro activity is against CMV (see Table 295.4), although it is also as active as acyclovir against HSV-1 and HSV-2 and almost as active against VZV.
