                                                    Ganciclovir (RS-21592, BW-759, 2'-Nor-2'-deoxyguanosine) is an antiviral drug for feline herpesvirus type-1 with IC50 of 5.2 μM in
a cell-free assay.

                                                    A correlation was found between the dose of ganciclovir exposure and a decrease in total cell number when duration exceeded 2 days
(r(2)=0.92 and 0.93 after 7 and 14 days, respectively). High levels (20 mg/l) of ganciclovir were not more toxic than lowest levels (1
mg/l) for the shortest durations of ganciclovir exposure (1 and 2 days). Moreover, 50% cytotoxic concentrations markedly decreased
with the duration of ganciclovir exposure (374-3 mg/l from 1 to 14 days respectively) after 14 days of culture.

                                                    Ganciclovir (GCV)-treated CMV-infected mice had lower ABR (P < 0.0001, Kruskal-Wallis test) and DPOAE (P < 0.0001)
thresholds compared to CMV-infected untreated mice, indicating that GCV protected mice from CMV-induced hearing loss. Viral
load in infected populations undergoing GCV treatment was significantly decreased (P = 0.03) relative to untreated mice. GCV
treatment alone had no effect on ABR and DPOAE compared to untreated, uninfected controls (P = 0.1, P = 0.24, respectively). GCVtreated mice received increased protection from OHC loss when compared to untreated groups, with total OHC losses of
approximately 7% and 14%, respectively (P < 0.05). Neutropenia was absent after 7 days of GCV treatment.
