Pharmacokinetic parameters after intravenous administration of pravastatin (5 mg/kg) to BDC rats and the serum biochemistry parameters predose

The individual TBIL values in the normal and mild HB groups ranged from 0.00 to 0.19 and 0.33 to 0.75 mg/dl, respectively. The Cplasma,1.5h and Cliver,1.5h represent the concentrations of plasma and liver, respectively, collected at 1.5 hours postdose. Data represent the mean ± S.E.M. of three animals.
