通过评价盐酸噻吩诺啡片在阿片类依赖者脱毒后预防复吸的有效性与安全性，为后续试验给药方案确定提供科学依据.

确定通过丁丙诺啡舌下片脱毒/诱导，再引入盐酸噻吩诺啡片的临床桥接方案，为噻吩诺啡控制阿片类依赖复吸的临床研究做准备。

Opioid addiction is common worldwide. Thienorphine hydrochloride is a newly partial opioid receptor agonist drugs. It's affinity with opioid receptors was much higher than opioids, which could effectively prevents opioid dependence by stop opioids competition for opioid receptors and causing opioid dependence. The aim of this research was to determine whether thienorphine hydrochloride would reduce opioid use and better preventing relapse among opioid addicts.
