Abstract: Animal models prepared by treatment with carbon tetrachloride (CCl4) have been used to examine drug disposition in hepatic disorder. However, previous studies demonstrated that systemic administration of CCl4 impaired not only hepatic but also renal function. We recently reported that application of CCl4 to the rat liver surface produced hepatic damage without impairing renal function. In the present study, we examined the pharmacokinetics of phenol red in our developed rat model. The rats treated with CCl4 by liver surface application exhibited decreases in the biliary clearance of phenol red in comparison with normal rats from 0.54±0.03 to 0.31±0.06 ml/min, suggesting hepatic damage. In these rats, the renal clearance of phenol red did not decrease (0.50±0.16 ml/min vs. 0.46±0.07 ml/min in normal rats). On the other hand, oral and intraperitoneal treatments with CCl4 reduced not only the biliary clearance of phenol red (0.34±0.03 ml/min in p.o. treated rats, 0.18±0.01 ml/min in i.p. treated rats) but also the renal clearance (0.26±0.05 ml/min in p.o. treated rats, 0.18±0.06 ml/min in i.p. treated rats) as compared with normal rats. These findings indicate that the rat model of liver damage prepared by liver surface application of CCl4 is useful to investigate the effects of hepatic disorder on the pharmacokinetics of drugs.
