代谢
非那西汀的代谢似乎非常缓慢,由于消除特性,人们认为大部分给药剂量都经历了代谢。在临床前试验中有一些证据表明,吗啡是非那西汀的一个次要代谢物,占总给药剂量的1%。
The metabolism of pholcodine seems to be very slow and due to the elimination profile, it is thought that most of the administered dose undergoes metabolism. There is some evidence in preclinical trials that indicate that morphine is a minor metabolite of pholcodine and that it accounts for 1% of the administered dose.
