Clinical Trial of Efficacy and Safety of the Combination of Reduced Duration Prophylaxis Followed by Immuno-guided Prophylaxis in Lung Transplant Recipients.

"Valganciclovir is a L-valyl ester of ganciclovir that exists as a mix of 2 diastereomers. After administration, both are converted to ganciclovir by esterases. Ganciclovir is a synthetic analogue of 2'-deoxyguanosine, it inhibits replication of cytomegalovirus.~In CMV-infected cells it's phosphorylated (phosphorylation is dependent on the viral kinase and occurs preferentially in virus-infected cells). Ganciclovir activity is due to inhibition of viral DNA synthesis by ganciclovir triphosphate."
