AUC, Area under the concentration vs time curve; C0, Initial blood concentration after IV dose; CL, plasma clearance; Vd, Volume of distribution; Cmax, maximum concentration in systemic circulation following dose; Tmax, time of Cmax; T1/2, time for blood concentration to reduce by half; F, percent of dose reaching systemic circulation unchanged. ND, not determined. 3 animals were used for each of the 11029 and 17028 study; 6 animals were used for 19029 study.
