密歇根州卫生与公众服务部警告新型药物可能导致过量服用死亡。 Michigan Department of Health and Human Services warns of new drug causing overdose deaths. 美托咪啶是一种未经批准用于人类的兽用镇静剂，已导致全州范围内发生过量服用致死事件。 Medetomidine, a veterinary tranquilizer not approved for human use, has been identified in overdose deaths across the state. 它会导致心率减慢、血压降低以及大脑和脊髓活动减少。 It can cause slowed heart rate, low blood pressure, and decreases in brain and spinal cord activity. 美托咪啶比赛拉嗪的药效更强，而且不会被纳洛酮等药物逆转。 Medetomidine is more potent than xylazine and is not reversed by medications such as naloxone. 自三月份以来，尸检毒理学检测已发现三起因美托咪啶过量服用而死亡的病例。 Since March, three overdose deaths have been identified involving medetomidine during postmortem toxicology testing.
