TABLE 7.

The Kp,pred and Kp,uu,pred values and the DA,pred values, using the pharmacokinetic parameters obtained from the compartmental BBB model describing the brain and plasma concentration-time profiles after administration of a single intravenous bolus (3 mg/kg, i.v.; N = 3 to 4 at each time point) or oral dose (30 mg/kg, PO; N = 4 at each time point) in FVB wild-type, Bcrp1(−/−), Mdr1a/b(−/−), and/or Mdr1a/b(−/−)Bcrp1(−/−) mice

The parameters are presented as the mean estimate.
