title: Femoxetine clearance in patients with liver cirrhosis.
abstract: The pharmacokinetics of femoxetine (a 5-HT uptake inhibitor with antidepressive effect) was studied in 12 patients with liver cirrhosis and in 6 healthy controls after a single oral dose of femoxetine HC1. The average blood concentration of femoxetine, as assessed by the values of AUC (area under the plasma concentration/time curve), was significantly higher in the patients with liver cirrhosis than in the healthy controls in spite of dose reduction in the patients. The elimination half-life of femoxetine was within the normal limits in most of the patients. The oral clearance of femoxetine was considerably lower in patients, (0.65-4.02 1/hr/kg) than in the controls (8.13- greater than 50 1/hr/kg). It was not directly related to the metabolic function of the liver, measured as the galactose elimination capacity being 0.015-0.024 mmol/min./kg and 0.033-0.041 mmol/min./kg, respectively. When treating patients with reduced liver function, it is recommended to reduce the doses and to monitor closely the plasma levels.
