Ibogaine is a natural chemical compound, which belongs to the indole alkaloid family. It can be naturally found within the root bark of african plant Tabernanthe iboga. Ibogaine plays a significant role among tribal cultures. Ibogaine, in small amount, causes reduction of hunger, thirst and exhaustion. In bigger amount, however, it can cause intensive visions. Other effects include reduction or complete disappearance of absitnence symptoms visible in people addicted to the nicotine, alcohol, methamphetamine, cocaine or opioids, what has been scientifically proven after the tests on animals and small groups of people...

The indole alkaloid ibogaine, present in the root bark of the West African rain forest shrub Tabernanthe iboga, has been adopted in the West as a treatment for drug dependence. Treatment of patients requires large doses of the alkaloid to cause hallucinations, an alleged integral part of the patient's treatment regime. However, case reports and case series continue to describe evidences of ataxia, gastrointestinal distress, ventricular arrhythmias and sudden and unexplained deaths of patients undergoing treatment for drug dependence...

Powdered roots of iboga (Tabernanthe iboga) contain ibogaine, an alkaloid that has been used to treat addictions. We report the case of a 30-year-old woman who died after ingesting a powder labeled as Tabernanthe iboga she had bought online. Analysis of the powder revealed the absence of ibogaine but the presence of toxic alkaloids (ajmaline, yohimbine and reserpine) found in Rauvolfia sp. plant species. An original and specific LC-MS/MS method developed to quantify ajmaline, yohimbine and reserpine showed respective concentrations of 109...

BACKGROUND: Opioid use disorders (OUD) translate into major health, social, and economic consequences. Opioid agonist medications, which generally require long-term administration, are the mainstay pharmacological treatment of OUD. However, a large proportion of individuals with OUD either refuse or fail to respond to these therapies. Ibogaine, a naturally occurring substance found in the Tabernanthe iboga plant, has shown potential to bring about transformative or spiritual experiences that have reportedly been associated with long-term abstinece...

We present the application of a bioinspired collective synthesis strategy in the total syntheses of seven iboga-type indole alkaloids: (±)-tabertinggine, (±)-ibogamine, (±)-ibogaine, (±)-ibogaine hydroxyindolenine, (±)-3-oxoibogaine hydroxyindolenine, (±)-iboluteine, and (±)-ervaoffines D. In particular, tabertinggine and its congeners serve as iboga precursors for the subsequent biomimetic transformations into other iboga-type alkaloids.

OBJECTIVE: The iboga alkaloids are a class of small molecules defined structurally on the basis of a common ibogamine skeleton, some of which modify opioid withdrawal and drug self-administration in humans and preclinical models. These compounds may represent an innovative approach to neurobiological investigation and development of addiction pharmacotherapy. In particular, the use of the prototypic iboga alkaloid ibogaine for opioid detoxification in humans raises the question of whether its effect is mediated by an opioid agonist action, or if it represents alternative and possibly novel mechanism of action...

Ibogaine is a naturally occurring alkaloid derived from the roots of the rain forest shrub Tabernanthe iboga. Deaths have occurred temporarily related to the use of ibogaine. However, although not licensed as therapeutic drug, and despite evidence that ibogaine may disturb the rhythm of the heart, this alkaloid is currently used as an anti-addiction drug in alternative medicine for detoxification purposes. We report the case of a man who died suddenly 12-24 h after ibogaine use for alcohol detoxification treatment...

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...

Ibogaine is a psychoactive alkaloid derived from Tabernanthe iboga, a plant used in initiatory rituals in West Central Africa. Largely because of ibogaine's status as a Schedule I substance in the U.S., the development of ibogaine's use in the treatment of drug addiction took place outside conventional clinical and medical settings. This article reviews the history of ibogaine's use in the treatment of drug addiction, and discusses progress made towards, and obstacles blocking, the establishment of controlled clinical trials of ibogaine's efficacy...

Ibogaine is a naturally occurring psychoactive alkaloid extracted from the roots of the Tabernanthe iboga plant, which in alternative medicine is used to treat drug dependency. However, this upcoming, online advocated therapy can be dangerous due to its potentially lethal adverse effects. We present three cases in which toxic side effects were noted. We used the Naranjo scale to estimate the probability of a causal relationship between these effects and ibogaine. Findings in these three cases are suggestive of a causal relationship between the use of ibogaine and serious respiratory and cardiac problems (including lengthening of the QT interval)...

An indole alkaloid, ibogaine is the principal psychoactive component of the iboga plant, used by indigenous peoples in West Africa for centuries. Modulating multiple neurotransmitter systems, the drug is a potent hallucinogen in humans, although its psychotropic effects remain poorly understood. Expanding the range of model species is an important strategy for translational neuroscience research. Here we exposed adult zebrafish (Danio rerio) to 10 and 20mg/L of ibogaine, testing them in the novel tank, light-dark box, open field, mirror stimulation, social preference and shoaling tests...

Alcoholism is a medical, social, and economic problem where treatment methods mostly include difficult and long-lasting psychotherapy and, in some cases, quite controversial pharmacological approaches. A number of medicinal plants and pure natural compounds are reported to have preventive and therapeutic effects on alcoholism and alcohol dependency, but their constituents, efficacy and mechanism of action are mostly unknown so far. Recently, kudzu [Pueraria lobata (Willd.) Ohwi], St. John's wort (Hypericum perforatum L...

Ibogaine, an alkaloid derived from the African shrub Tabernanthe iboga, has shown promising anti-addictive properties in animals. Anecdotal evidence suggests that ibogaine is also anti-addictive in humans. Thus, it alleviates drug craving and impedes relapse of drug use. Although not licensed as therapeutic drug, and despite evidence that ibogaine may disturb the rhythm of the heart, this alkaloid is currently used as an anti-addiction drug in alternative medicine. Here, we report that therapeutic concentrations of ibogaine reduce currents through human ether-a-go-go-related gene potassium channels...
