Cl as a percentage of liver blood flow is calculated as compound Cl (blood or plasma)/species hepatic blood flow. Hepatic blood flow estimates of 126, 77.6, 56.1, and 44 mL/min/kg were used for mouse (0.02 kg), rat (0.25 kg), dog (10 kg), and cynomolgus monkey (5 kg), respectively.26
Blood clearance was used.
Dosed i.v. at 1 mg/kg in 5–10% DMSO/85–95% HP-β-CD (20% in sterile water) with or without solutol or DMSO/30% sulfobutylether- β-cyclodextrin (5/95).
Dosed i.v. at 1 mg/kg in DMSO/20% hydroxypropyl-β-cyclodextrin (10/90, pH adjusted).
