Pharmacokinetics of 3H-pipethiaden after single oral and intravenous administration in rats.
Tritium labelled anti-migraine drug 4-(1-methyl-4-piperidyliden)-4,9-dihydrothieno[2,3-c]-2-b enzothiepine (pipethiaden) was prepared. After oral and intravenous administration to rats not only the courses of total radioactivity in plasma and various organs were determined, but by means of TLC-radiometry also the levels of pipethiaden itself. After the oral dose 1.35 mg/kg the plasma levels of pipethiaden did not exceed 3.5 ng/ml. Some pharmacokinetic parameters (e.g. t1/2 el-4 h) were calculated by compartmental analysis of plasma levels.
