针对阿片类依赖者应用丁丙诺啡（美沙酮）脱毒或诱导桥接引入盐酸噻吩诺啡片进行防复吸治疗，及既定用药方案下，患者对盐酸噻吩诺啡片耐受的观察，为IIa期试验针对该目标受试者人群的给药方案设计提供依据。

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.

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.
