Ganciclovir exposure under a 450 mg daily dosage of valganciclovir for cytomegalovirus prevention in kidney transplantation: a prospective study.

This prospective study aimed at determining the ganciclovir exposure observed under a daily dosage of 450 mg valganciclovir routinely applied to kidney transplant recipients with a GFR above 25 mL/min at risk for cytomegalovirus (CMV) disease. Ganciclovir levels at trough (C(trough)) and at peak (C₃(h)) were measured monthly. Ganciclovir exposure (area under the curve [AUC₀₋₂₄]) was estimated using Bayesian non-linear mixed-effect modeling (NONMEM).
