  • a n = 262.

  • b % CV, percent coefficient of variation; LD/MD, loading dose/maintenance dose.

  • c Based on estimated individual PK parameters from the final PK model with an infusion rate of 1 mg/min.

  • d t1/2β is the predominant elimination half-life that characterizes the majority of the concentration-time profile.
