Orally, available in 450 mg pink tablets. Dosing is calculated to provide appropriate doses of ganciclovir; 900 mg of valganciclovir orally every 12 hours is equivalent to 5 mg per kilogram of body weight of intravenous ganciclovir, also every 12 hours.
Oral bioavailability is approximately 60%. Fatty foods significantly increase the bioavailability and the peak level in the serum.
It takes about 2 hours to reach maximum concentrations in the serum.
Valganciclovir is eliminated as ganciclovir in the urine, with a half-life of about 4 hours in people with normal kidney function.
It has been proposed that valganciclovir could be used in the treatment of chronic fatigue syndrome, following some reported success in 9 out of 12 patients at Stanford University in California, although further research is required . A study is planned at Stanford for early 2007.
