Ganciclovir is available intravenously and orally for the treatment of
CMV infection in immunocompromized patients. Saigal and colleagues
demonstrated that intravenous dosing of ganciclovir resulted in plasma
concentrations above the IC50 for susceptible strains for most of the
dosing interval, while standard oral doses resulted in levels far
below the IC50.
Comment: This study raises the serious concern that oral
therapy with ganciclovir would be ineffective, could lead to relapse
after initial intravenous therapy, and result in the promotion of
resistant CMV strains. The results may explain failure of oral
ganciclovir to prevent recurrent CMV infection.
