Effect of acute hepatic failure on epirubicin pharmacokinetics after intrahepatic arterial injection in rats

In the case of cancer chemotherapy for hepatocellular carcinoma, anthracycline anticancer agents such as epirubicin are widely used, and have typically been given by intrahepatic arterial (i.a.) infusion to increase treatment efficacy and to reduce systemic toxicity. The anthracyclines are eliminated primarily by the liver, and the use of these drugs in patients with hepatic failure can be difficult. In this study, we investigated the effect of acute hepatic failure on the pharmacokinetics of epirubicin after i.a. injection in rats. Experimental acute hepatic failure was induced by carbon tetrachloride-treatment. Epirubicin was injected into the hepatic artery or the saphenous vein of the rats at a dose of 2 mg/kg. After both intravenous (i.v.) and i.a. injection, the serum concentration and the AUC 0-24 of epirubicin in hepatic failure rats were significantly higher than the values in control rats. The AUC 0-24 ratio of hepatic failure (i.a.) to control (i.a.) was higher than the ratio of hepatic failure (i.v.) to control (i.v.). These results suggest that the influence of hepatic failure on serum epirubicin concentration is larger with the i.a. route than with the i.v. route. The liver concentration of epirubicin after i.a. administration in hepatic failure rats was significantly lower than that in control rats. This result suggests that the effect of the liver-selective drug targeting after i.a. injection in hepatic failure rats is lower than in normal rats. Therefore, we should be careful when administering epirubicin by the i.a. route in patients with acute hepatic failure.

Effect of acute hepatic failure on the hepatic first‐pass effect of 5‐fluorouracil in rats

Objectives In cancer chemotherapy for hepatocellular carcinoma, 5‐fluorouracil is widely used and has typically been given by intrahepatic arterial (i.a.) infusion to increase treatment efficacy and reduce systemic toxicity. 5‐Fluorouracil is eliminated primarily by the liver and so the hepatic first‐pass effect after intrahepatic arterial administration of 5‐fluorouracil may be lower in patients with hepatic failure, and systemic toxicity may not be reduced. In this study, we have investigated the effect of acute hepatic failure on the first‐pass effect of 5‐fluorouracil in rats. Methods Experimental acute hepatic failure was induced by treatment with carbon tetrachloride (CCl₄). 5‐Fluorouracil was infused for 15 min into the hepatic artery or the saphenous vein of rats at a dose of 1.25 mg/kg. Key findings Hepatic availability in 50% CCl₄‐treated (severe hepatic failure) rats was higher than in controls. Conclusions The hepatic first‐pass effect after intrahepatic arterial administration of 5‐fluorouracil was lower in severe hepatic failure. Therefore, the reducing effect of the systemic toxicity after intrahepatic arterial administration may be lower in severe hepatic failure.

Expression and function of P-glycoprotein in rats with carbon tetrachloride-induced acute hepatic failure.

Acute hepatic failure was induced experimentally in rats by intraperitoneal injection of 2.5 mL kg(-1) carbon tetrachloride (CCl4), and the effects on the expression and function of P-glycoprotein in the liver, kidney and brain were evaluated. The CCl4 injection significantly increased the indicators of hepatic function (glutamate oxaloacetate transaminase, glutamate pyruvate transaminase), but not of renal function (blood urea nitrogen, glomerular filtration rate). In rats with acute hepatic failure, the hepatic P-glycoprotein concentration increased 1.5-fold and the ATP concentration decreased to approximately 40% that in control rats. In contrast, P-glycoprotein concentrations in the kidney and brain and ATP concentrations in the kidney remained unchanged. The in-vivo P-glycoprotein function in these tissues was suppressed as evaluated by biliary and renal secretory clearances and brain distribution of rhodamine 123, a P-glycoprotein substrate. These findings suggest that factors other than P-glycoprotein concentration are involved in the systemic suppression of P-glycoprotein function in diseased rats. In Caco-2 cells, plasma collected from CCl4-treated rats exhibited a greater inhibitory effect on P-glycoprotein-mediated transport of rhodamine 123 than that from control rats, suggesting the accumulation of an endogenous P-glycoprotein substrate/inhibitor in the plasma of diseased rats. In fact, the plasma concentration of corticosterone, an endogenous P-glycoprotein substrate, increased 2-fold in CCl4-treated rats compared with control rats. It was demonstrated that P-glycoprotein function is systemically suppressed in rats with CCl4-induced acute hepatic failure, not only in the target organ (liver), but also in other organs (kidney and brain), although the P-glycoprotein concentration remained unchanged in the kidney and brain, and increased in the liver. In the systemic suppression of the P-glycoprotein function in the diseased state, the alteration of plasma concentrations or components of endogenous P-glycoprotein-related compounds, such as corticosterone, would likely be involved.
