摘要 大鼠im抗孕唑很快被吸收并分布到各组织中,其中以子宫、卵巢含量最高,其次为肺、心、肾、肌肉,脑、骨中含量较少。大鼠iV抗孕唑后24h,从粪、尿中排出原形药量为0.084±0.039%,168h排出0.396±0.071%。12h内从胆汁排泄的原形药量占给药剂量的1.62±2.04%。可见原药进入体内后很快被代谢。im抗孕唑后1h,注射部位肌肉中的余留量约为给药剂量的50%。t_(1/2)(Ke)=228.812±96.112(min)。 DL111-IT, 3-(2-ethylphenyl)-5-(3-methoxyphenyl)-1H-1, 2, 4,-triazol, is a new contragestational agent. In this paper its absorption, distributions excretion in rats are reported.1h after im administration the peak level of DL111-IT was found in utero-ovaries. The decreasing order of DL111-IT distribution in other organs or tissue was as follows: lungs, heart, kidneys, muscle, brain, femur. Only trace level of DL111-IT was detected in these tissues 8h after im DL111-IT.After iv in rats, the total DL111-IT excreted in urine and feces was found to be 0.39±0.071% within 168h. 1.62+2.04% of an iv dose was recovered from the bile collected for 12h.pharmacokinetic parameters of one compartment model im DL111-IT 5mg/kg in 5 rats were t1/2(ke)=228.812±96.112 min.
