摘要
萘丁美酮(Nabumetone,NAB)为一新型非甾体抗炎前体药物,本文通过整体实验,采用高效液相色谱法,测定犬服药后门静脉和股静脉中NAB和其主要活性代谢物6-甲氧基-2-萘乙酸(6-MNA),来评价NAB的肝首过代谢,结果表明:萘丁美酮几乎全部从肝脏代谢,在外周血液(股静脉中不能测出NAB原形药物。同时采用平衡透析法,测定了6-NMA蛋白结合率,6-MNA的浓度在5~40μg/ml范围内,血浆蛋白结合率为92.79g~98.11%。
Nabumetone(NAb)is a novel non-steroidal anti-inflammatory
prodrug.To evaluate its first-pass hepatic metabolism,We have determined nabumetone and its
major active metabiolite(6-MNA)in portal and femoral vein of dogs after oral admin-istration (80
mg/kg).The results indicated that unchanged nabumetone was not detectable in femoral vein and
undergone ex-itensive first-pass metabiolism. The protein binding rate of 6-MNA was 92. 79%~98.
11%when 6-MNA level was in 5~4oμg/mg.
