Abstract

The pharmacokinetics of eupatilin (an active components of Stillen, a new antigastritic agent) were investigated using UV-HPLC method. The quantitation limit of eupatilin was 10 ng/ml in plasma. After intravenous administration of eupatiln, 30 mg/kg to rats, the plasma concentrations of unchanged eupatilin declined rapidly with the mean terminal half-life of 0.101 hr. Total body clearance was 121 ml/min/kg, and fractions of dose excreted in urine and feces for 24 hr were only 2.5% and 0.919%, respectively. (omitted)
