Ibogaine for Anxiety Disorders

12 papers and 1 clinical trial exploring ibogaine as a treatment for anxiety disorders.

CompoundIndole Alkaloid

Ibogaine

A unique indole alkaloid with complex pharmacology, investigated primarily for its capacity to interrupt substance use disorders and withdrawal.

Anxiety Disorders

Anxiety disorders are the most common mental health conditions in the world, yet for primary anxiety (generalised anxiety, social anxiety, panic) the psychedelic evidence is surprisingly thin. The clear front-runner is LSD: MindMed’s MM120 met its Phase 2b endpoint in generalised anxiety disorder and is now in two Phase 3 trials. Most other psychedelic anxiety data comes from cancer and end-of-life distress, a different problem covered on our palliative page, or is measured as a side effect of treating depression.

Efficacy and Safety of the Neuroplastogen TSND-201 for the Treatment of PTSD A Randomized Clinical Trial

In a multicentre, double‑blind, placebo‑controlled phase 2 trial of 65 adults with chronic PTSD, once‑weekly oral TSND‑201 produced significantly greater reductions in clinician‑rated PTSD severity (CAPS‑5; LS mean difference 9.64, P = .01) and improvements in self‑reported symptoms, functioning and depression versus placebo. TSND‑201 was generally well tolerated — common adverse events included headache, decreased appetite, nausea, dizziness and transient blood‑pressure increases — supporting its potential as a rapid‑acting, durable treatment for PTSD.

Mystical experiences during magnesium-Ibogaine are associated with improvements in PTSD symptoms in veterans

This secondary analysis of an open-label study (n=30) of male Veterans with traumatic brain injury found that greater intensity of mystical experiences during magnesium-ibogaine treatment was associated with larger reductions in PTSD severity both immediately and one month post-treatment, as well as greater reductions in peak alpha frequency at one month.

Magnesium-ibogaine therapy effects on cortical oscillations and neural complexity in veterans with traumatic brain injury

This analysis of an open-label observational study (n=30) found that magnesium-ibogaine therapy in combat veterans with traumatic brain injury (TBI) led to slower brain wave patterns and reduced neural complexity on EEG, which correlated with improvements in PTSD, anxiety, and cognitive function at one-month follow-up.

Magnesium-ibogaine therapy in veterans with traumatic brain injuries

This observational study (n=30) evaluates ibogaine (up to 980mg/70kg) in combination with magnesium (1-2 hours before and 12 hours later) in male Special Operations Forces veterans with predominantly mild traumatic brain injury (mTBI). The study assessed changes in disability, PTSD, depression, and anxiety immediately and one month after treatment using various scales. Results show significant improvements in functioning and psychological symptoms with no serious adverse events.

Open-label study of consecutive ibogaine and 5-MeO-DMT assisted-therapy for trauma-exposed male Special Operations Forces Veterans

This open-label study (n=86) examined the effectiveness of psychedelic-assisted therapy (PAT) among trauma-exposed Special Operations Forces Veterans (SOFV) in Mexico. Results indicated significant improvements in self-reported PTSD symptoms, depression, anxiety, insomnia severity, post-concussive symptoms, satisfaction with life, psychological flexibility, and cognitive functioning from baseline to one-month follow-up. The combination of ibogaine and 5-MeO-DMT assisted therapy showed potential for providing rapid and lasting improvements in mental health functioning, with effects observed up to six months after treatment.

Predictors of psychedelic treatment outcomes among special operations forces veterans

This prospective study (n=86) examined the effects of ibogaine and 5-MeO-DMT treatment on U.S. Special Operations Forces Veterans with trauma exposure. Younger age and higher baseline levels of depression and anxiety were correlated with significant improvements in mental and psychosocial outcomes from baseline to 1-month follow-up. Greater intensity of changes in consciousness was linked to improved long-term mental health and psychosocial outcomes up to 6 months post-treatment.
