| species | dose (mg/kg)b | AUClast (μM·h) | AUCinf (μM·h) | CL (L/h/kg) | Vss (L/kg) | t1/2 (h) | MRT (h) |
|---|---|---|---|---|---|---|---|
| WH rat | 3 | 53.2 ± 8.08 | 60.1 ± 9.79 | 0.045 ± 0.004 | 2.63 ± 0.37 | 42.6 ± 6.14 | 50.2 ± 4.38 |
| beagle dog | 1 | 18.9 ± 5.9 | 19.1 ± 6.1 | 0.057 ± 0.017 | 1.12 ± 0.12 | 19.3 ± 2.5 | 20.6 ± 6.4 |
Values are the mean ± SD from 3 animals. AUClast = area under the concentration–time curve from 0 to the last quantified time point; AUCinf = area under the concentration–time curve extrapolated to time infinity; CL = systemic clearance; MRT = mean residence time; NCA = noncompartmental analysis; t1/2 = terminal elimination half-life; SD = standard deviation; Vss = volume of distribution at steady state; WH = Wistar Han.
Doses were administered via a 30 min IV infusion.
