Maribavir
Maribavir is an orally available, antiviral agent which inhibits the pUL97 kinase of cytomegalovirus (CMV) and is used to treat refractory forms of post-transplant CMV infection. Maribavir has been associated with low rates of mild-to-moderate serum aminotransferase elevations during therapy but has not been linked to cases of clinically apparent acute liver injury.
