  • a Parameters were calculated from mean blood concentration after intravenous administration of PL and butyryl-PL in rats (2.5 mg/kg for rats, equivalent to PL). AUC of drugs after administration in rats was calculated from mean plasma concentrations from time zero to infinity. AUCblood = AUCplasma × Rb. AUCblood,pl means the AUCblood of PL after administration of PL. AUCblood, Bu and AUCblood, Bu→pl mean the AUCblood of butyryl-PL and PL after administration of butyryl-PL, respectively. CLtotal,pl and CLtotal,Bu mean the total clearance of PL and butyryl-PL after administration of PL and butyryl-PL, respectively.
