RESUMO

Ibogaine is a psychotropic indole alkaloid extracted from the roots of the Tabernanthe iboga shrub from the Apocynaceae family. Depending on the taken dose, it can lead to stimulant effects, euphoria, visual and auditory hallucinations, along with auditory, olfactory, and gustatory synesthesia. In addition to its historical usage in spiritual rituals of African tribes, these days iboga extract presents a prohibited, alternative drug widely used as a part of addiction treatment. Ibogaine used in opioid withdrawal is associated with serious side effects and sudden deaths. Besides its main use as an anti-addiction medication in alternative medicine, in moderate doses (from 100mg to 1g) ibogaine most commonly causes a "trance-like state".In this paper, we report the case of a heroin addict who died suddenly 5-12 hours after oral ingestion of powder labeled Tabernanthe iboga which had been bought online and used in the process of detoxification during an addiction treatment. The man was found dead in a rented apartment, where he was undergoing the addiction treatment.External examination revealed no lesions other than nonspecific injuries on the legs. The autopsy showed congestion of internal organs and pulmonary edema. Histopathological analysis of the heart showed neither macroscopic nor microscopic abnormalities. The concentration of ibogaine was 3.26mg/L. Moreover, systematic toxicological analyses of biological samples showed the presence of morphine and codeine. These data suggest that death, which occurred unnaturally after initiation of the "treatment", was probably the result of the cardiovascular effects caused by the ibogaine powder.The presented case highlights the worldwide problem of various products being widely available over the internet and the danger associated with consumption thereof.

RESUMO

INTRODUCTION: Misuse of various new psychotropic substances such as ibogaine is increasing rapidly. Knowledge of their negative side effects is sparse. CASE PRESENTATION: We present a case of intoxication with the herbal substance ibogaine in a 22-year-old white man. After taking a cumulative dose of 38 g (taken in two doses), he developed visual memories, nausea and vomiting. He developed a generalized tonic-clonic seizure with additional grand mal seizures. He was treated with midazolam and levetiracetam. Extended drug screenings and computed tomography and magnetic resonance imaging findings were all negative. CONCLUSIONS: Knowledge of the side effects of ibogaine has mainly come from reports of cardiovascular complications; seizures are rarely mentioned and experimental findings are inconsistent. It seems that ibogaine acts like a proconvulsive drug at high doses.

RESUMO

UNLABELLED: Ibogaine, a psychotropic indole alkaloid, is gaining popularity among medical subcultures for its purported anti addictive properties. Its use has been associated with altered mental status, ataxia, gastrointestinal distress, ventricular arrhythmias, and sudden and unexplained deaths.Its pharmacokinetics in toxic states is not well understood. Case report:A 33-year-old man overdosed on ibogaine in an attempt to quit his use of heroin. He developed altered state of consciousness, tremor, ataxia,nausea, vomiting, and transient QT interval prolongation, which all remitted as he cleared the substance. Ibogaine was confirmed in his urine and serum with a peak serum concentration of 377 ng/mL. Nonlinear elimination kinetics and a formula match to its active metabolite noriobgaine were observed as well. CONCLUSION: This case presents the unique description of serial serum concentrations as well as urine and product-confirmed ibogaine toxicity with transient toxin-related QT interval prolongation.

RESUMO

We report the case of a man who died twelve hours after ingesting powdered iboga root, commonly taken for its stimulant and hallucinogenic properties. Ibogaine and ibogamine were quantified in the powder ingested and the victim's body fluids by GC-MS/MS after liquid-liquid extraction (Toxi-tubes A(®)). The concentrations of ibogaine measured in the blood samples taken at the scene and in the peripheral blood, urine, and gastric fluid samples taken during the autopsy were 0.65, 1.27, 1.7, and 53.5 µg/mL, while the iboga content in the powder was 7.2%. Moreover, systematic toxicological analyses of biological samples showed the presence of diazepam and methadone in therapeutic concentrations. Death was attributed to the ingestion of a substantial quantity of iboga in the context of simultaneous methadone and diazepam consumption.

RESUMO

In the present paper, we report for the first time the tissue distribution of ibogaine and noribogaine, the main metabolite of ibogaine, in a 48-year-old Caucasian male, with a history of drug abuse, found dead at his home after a poisoning involving the ingestion of root bark from the shrub Tabernanthe iboga. Ibogaine and noribogaine were quantified in tissues and fluids using a fully validated liquid chromatography-electrospray mass spectrometry method. Apart from cardiac tissue, ibogaine and noribogaine were identified in all matrices investigated. The highest concentrations were found in spleen, liver, brain, and lung. The tissue/subclavian blood concentration ratios averaged 1.78, 3.75, 1.16, and 4.64 for ibogaine and 0.83, 2.43, 0.90, and 2.69 for noribogaine for spleen, liver, brain, and lung, respectively. Very low concentrations of the two drugs were found in the prostatic tissue. Both ibogaine and noribogaine are secreted in the bile and cross the blood-brain barrier. Four other compounds were detected in most of the studied matrices. One of them was identified as ibogamine. Unfortunately, we were not able to positively identify the other three compounds because of the unavailability of reference substances. Two of them could possibly be attributed to the following oxidation products: iboluteine and desmethoxyiboluteine. The third compound could be ibogaline.
