[Lidocain clearance after oral and intravenous application in rats with low grade ANIT-cholestasis and galactosamine-induced hepatitis (author's transl)]. 1980

Each of 6 rats with a low grade of ANIT-cholestasis and a low grade of GalN-hepatitis received either 3 mg Lidocain i.v. or 24 mg Lidocain orally. The plasma concentrations of Lidocain were measured over a period of 3 1/2 hrs. The systemic clearance of Lidocain (Cli.v. = Di.v. divided by AUCi.v.) was significantly increased on ANIT-cholestasis (17 +/- 3) and GalN-hepatitis rats (13 +/- 2) (control rats: 7 +/- 1 ml/min x 100 g bw). Oral clearance of Lidocain (Clor = Dor divided by AUCor) was not significantly different in the three respective groups. In both groups with experimental liver disease the hepatic blood flow--calculated by comparing the systemic to the oral clearance--was significantly increased (22 +/- 4 and 19 +/- 3 vs 8 +/- 1 ml/min x 100 g bw). Due to this increase, the hepatic extraction ratio of Lidocain was significantly decreased (ANIT-cholestasis 0.73 +/- 0.07; GalN-hepatitis 0.74 +/- 0.05; controls 0.85 +/- 0.03). Because of an increase of systemic Lidocain clearance, no toxic plasma concentrations were observed.
