Ibogaine Found in a West African plant Tabernanthe iboga. Used in Bwiti religion

Gabon’s first President, Leon Mba was Bwitist and defended T. iboga use in French colonial courts.

Scientific literature for fifty years described the plant as 1m - 2m in height but, examples exist in the forest 5m in height (Omboue)

Iboga alkaloids are concentrated in the bark of the root

Usable forms include scraped or ground root bark 2% - 4%

Total Alkaloid extract 15%

Purified Chemical 95% - 99%

Proposed as an approved regulated drug

First scientific publication of ibogaine antiaddictive effects

- Dzoljic et al. -

Additional research supports Dr. Dzoljic’s findings. Dr. Stanley D. Glick at Albany Medical College begins the publication of what will become dozens of research papers

showing reduction in drug use and withdrawal.

Neurotoxicity questions

Xu et al. eventually produce research

showing no neurotoxicity at clinical doses (2000)

Xu et al. accomplished research in part at the National Center for Toxicological Research an FDA laboratory. The research demonstrated no neurotoxicity in rats at 25 mg/kg.

Other research indicated no evidence of neurotoxicity in the primate and mouse, and postmortem neuropathological examination in a woman treated with up to 30 mg/kg.

Ibogaine: Multiplemechanisms of action

& receptor system effects where drugs of abuse also show activity

•Dopamine

•Opiate

•Serotonin•NMDA (N-methyl-D-aspartic acid)

•Nicotinic•GDNF (Glial cell derived neurotrophic factor)

•Signal transduction independent of receptor binding

These systems define the pharmacology of human behavior, affecting pain, pleasure, anxiety and depression as well as, neuron growth with an inherent impact on memory and learning.

Clinical Studies“Safety and Efficacy”

In 2004, in support of clinical studies NIDA makes available a Drug Master File (DMF) provided to FDA comprising 16 volumes of data of approximately 4,000 pages.

Partial list of broad-ranging studies in FDA Drug Master File (DMF) included in the 16 volumes of data submitted by US National Institute on Drug Abuse (NIDA) for ibogaine.

Opioid withdrawal in

human subjects

Objective Opioid Withdrawal Signs

Claudio Naranjo, MDuse in psychotherapy

Clinical Toxicology, 2(2):209-224, 1969

Outside of Africa, Naranjo was first to describe:

1. The waking dreamstate

2. Retrieval of early memories

3. Motion related nausea

Stigma

A mark of disgrace associated with a particular circumstance, quality or person: for instance the stigma of chemical dependence.

Ibogaine Effects on Stigma

Ibogaine has the ability to remove the stigmatized condition, transforming the patient to a state often described as a preaddictive. The transformation of a stigmatized person into one who is not stigmatized will affect the individual, allowing a greater contribution to self and

society, improving quality of life issues.

Typology of ibogaine providers and #s of patients treated (ca. 2006) TOTAL = 3414

1. Medical model (824)2. Lay provider/treatment guide (1213)3. Activist/self-help (200)4. Religious/spiritual (1177)

Reasons for treatment

1. Total = 3414 (ca. 2006)2. Substance-related disorders = 68%3. Opioid withdrawal = 53%

Taking the hidden population estimates (20% - 30%) into account allow an estimated range of approximately 4300-4900 individuals who took ibogaine or iboga alkaloids outside of Africa as of February 2006.
