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.
在大鼠中研究了静脉注射、腹腔注射和口服给药后14C-GFA的吸收、代谢和排泄情况。腹腔注射给药后,GFA被完全吸收,口服给药后约83%被吸收。GFA通过胆汁100%排泄,并经历广泛的肠肝循环。给予20mg/kg 14C-GFA后,几乎所有放射性在96小时后被消除,超过80%通过粪便排出。
