Ibogaine, a naturally occurring psychoactive substance derived from the African iboga plant, has garnered significant attention for its potential in treating various forms of addiction, including opioids, nicotine, and beyond.
Despite its complex pharmacological landscape, preliminary evidence suggests ibogaine’s multifaceted mechanisms of action offer a unique approach to addiction treatment.
Understanding Ibogaine’s
Mechanisms of Action
Opioid receptor systems
Ibogaine binds mu, kappa, and delta opioid receptors. However, its precise mechanisms at these receptor sites are still being defined. Ibogaine is considered a weak mu opioid receptor antagonist which is associated with anti-craving effects and opioid detoxification. Ibogaine is suspected to be a kappa opioid receptor agonist which is associated with analgesic, anti-depressant, anti-addictive, and neuroprotective effects.
Serotonin system
The serotonin transporter (SERT) is the site of action of the most common class of antidepressants known as SSRIs (selective serotonin reuptake inhibitors), which include Lexapro, Zoloft, and Prozac. Like SSRIs, ibogaine and its metabolite noribogaine are very strong serotonin reuptake inhibitors (i.e., they raise the level of serotonin). Ibogaine is a non-competitive inhibitor of SERT, which is suspected to contribute to ibogaine’s anti-depressant effects and improving negative mood states in post-acute withdrawal.
Dopamine system
Ibogaine demonstrates a binding affinity for the dopamine transporter (DAT), and has demonstrated biphasic effects on dopamine levels. Ibogaine is demonstrated to interact with DAT and result in adaptive dopamine signaling and restore functional activity in regions associated with opioid addiction and reward processing, such as the ventral tegmental area and nucleus accumbens.
NMDA antagonism
NMDA antagonism is associated with mitigation of withdrawal, opioid-reward, and drug-seeking behaviors. NDMA is also implicated in depression. Ketamine, which has a similar action, is utilized to mitigate opioid withdrawal symptoms, as well as to treat major depressive disorder.
GNDF stimulation
Ibogaine stimulates the production of glial-derived neurotrophic factor (GDNF). GDNF is identified as a treatment target for addiction. GDNF can restore damaged dopamine neurons. Many conditions can dysregulate or damage dopamine neurons, including chronic pain, Parkinson’s disease, severe drug addiction, and traumatic brain injury (TBI).
Nicotinic receptors
Ibogaine modulates nicotinic acetylcholine receptors, specifically as a noncompetitive antagonist for the α3β4 subtype. Antagonism of this receptor is implicated in mitigating and attenuating opioid withdrawal symptoms. Alternate treatments such as bupropion and mecamylamine are α3β4 antagonists often used in treatment of nicotine addiction.
Anti-inflammatory and antinociceptive effects
Opioid use disorder is associated with inflammation and pain states. Ibogaine demonstrates receptor affinity to sigma receptors, which are associated with modulating inflammatory responses. The NMDA antagonism of ibogaine may also possess anti-inflammatory and anti-nociceptive effects, addressing contributing or precipitating factors to opioid use and underlying factors maintaining dependency.
Psychedelic effects
The psychedelic effects of ibogaine are shown to induce insight into the underlying psychological contributors to addictive behavior. The psychedelic effects of ibogaine are likely mediated through a complex interaction among kappa opioid agonism, NMDA antagonism, and serotonergic transmission.
Conclusion
Ibogaine treatment presents a multifaceted approach to addiction recovery, targeting the complex interplay of neurochemical systems involved in dependency.
By addressing both the physiological and psychological dimensions of addiction, ibogaine offers a promising alternative for those seeking a path to recovery.
