Ibogaine is a psychoactive indole alkaloid that has been investigated for use as a treatment for opioid addiction. While not commercially available in the United States, it is available via Internet suppliers. Ibogaine use has been associated with significant cardiac and neurologic effects, such as QT-segment prolongation, cardiac dysrhythmias, hallucinations, seizures, and central nervous system depression. We present a case of verified ibogaine exposure with associated QTc prolongation and torsade de pointes with qualitative analysis of the ingested substance, and examine the history, social context, availability, and perceptions of ibogaine's effects and safety.
A 34-year-old white woman with medical history significant for heroin and cocaine use disorder presented with reported seizures 1 day after ingestion of 2 g ibogaine powder purchased from an Internet supplier. Shortly after ingestion, she experienced hallucinations and was reported by family to have four to five seizure-like episodes, at one point becoming apneic. In the emergency department, she was noted to have QTc prolongation and several episodes of torsade de pointes. Qualitative analysis confirmed the presence of ibogaine in the empty foil packages containing the ingested substance. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: As increasing numbers of opioid-dependent patients attempt to curtail their substance use disorders, we anticipate a rise in ibogaine exposures, necessitating awareness by front-line clinicians in recognizing and treating a drug exposure that can rapidly become life-threatening.
伊博格碱是一种具有精神活性的吲哚生物碱,已被研究用于治疗阿片类药物成瘾。虽然它在美国没有商业销售,但可通过互联网供应商获得。使用伊博格碱与显著的心脏和神经效应有关,如QT段延长、心律失常、幻觉、癫痫发作和中枢神经系统抑制。我们报告一例经证实的伊博格碱暴露病例,伴有QTc延长和尖端扭转型室速,并对摄入物质进行定性分析,同时审视伊博格碱的使用历史、社会背景、可得性以及对其效果和安全性的认知。
一名34岁有海洛因和可卡因使用障碍病史的白人女性,在从互联网供应商购买2克伊博格碱粉末并服用1天后出现癫痫发作。服药后不久,她出现幻觉,家人报告她有四到五次癫痫样发作,一度出现呼吸暂停。在急诊科,发现她有QTc延长和几次尖端扭转型室速发作。定性分析证实含有摄入物质的空箔包装中存在伊博格碱。急诊医生为何应知晓此事?:随着越来越多的阿片类药物依赖患者试图戒除其物质使用障碍,我们预计伊博格碱暴露事件会增加,这就需要一线临床医生提高认识,以便识别和治疗这种可能迅速危及生命的药物暴露情况。
