Systematic review and meta-analysis of preclinical animal studies

What was done
A systematic review and meta-analysis of 27 animal studies evaluating ibogaine's efficacy in reducing addictive behaviour in animal models of substance use disorders, its toxic effects on motor functioning, cerebellum, and heart rhythm, and its neuropharmacological mechanisms.
What was found
Meta-analysis of 27 studies found ibogaine reduced drug self-administration, especially within the first 24 hours, but had no effect on drug-induced conditioned place preference. Ibogaine caused motor impairment in the initial 24 hours and cerebral cell loss weeks after administration. Data on cardiac rhythm and neuropharmacological mechanisms were limited. No exact numerical estimates were reported in the abstract.
Why it matters
This review compiles the preclinical evidence for ibogaine's anti-addictive effects while highlighting key toxicity risks such as delayed cerebral cell loss and motor impairment.
Limits
Findings are entirely derived from animal models and cannot establish human clinical efficacy or safety. The abstract reports no numerical effect sizes or confidence intervals, finds no effect on conditioned place preference, and notes limited data on cardiotoxicity.
