Disposition of vorinostat, a novel histone deacetylase inhibitor and anticancer agent, in preclinical species.

The disposition of vorinostat, an anticancer agent, was investigated in rats and dogs. Vorinostat possessed high serum clearance, a short elimination half-life and low oral bioavailability in both species. The renal route played an important role in the elimination of drug-related material and vorinostat was eliminated primarily by metabolic biotransformation.
