abstract: Absorption, metabolism and excretion of 14C-GFA following i.v., i.p. and oral application are investigated in rats. After i.p. administration GFA is completely absorbed, after oral dosage about 83% are absorbed. GFA is excreted by 100% via bile and undergoes extensive enterohepatic circulation. After administration of 20 mg/kg 14C-GFA nearly all radioactivity is eliminated after 96 h, more than 80% via the faeces.
