In vivo experiments were conducted using male Sprague–Dawley rats (N = 3/group).
Percent rat plasma protein binding (PPB) of 8 measured in vitro following separation by ultracentrifugation.
Clearance (CL), volume of distribution (Vdss), half-life (T1/2), and area under the plasma concentration–time curve (AUC0→48 h) determined following a single intravenous dose (1 mg/kg; vehicle = DMSO).
AUC0→48 h determined following a single oral dose (3 mg/kg; vehicle = 20% HPBCD, 1% HPMC, and 1% pluronic F68, pH 2.1, with MSA).
Percent bioavailability (F) calculated using AUC0→∞ values determined from the 1 (iv) and 3 mg/kg (po) doses.
AUC0→48 h determined following a single oral dose (100 mg/kg; vehicle = 20% HPBCD, 1% HPMC, and 1% pluronic F68, pH 2.1, with MSA).
