Clinical Scorecard: Long-term Abstinence Achieved in Severe Ketamine Use Disorder After Ibogaine Intervention: A Case Study
At a Glance
| Category | Detail |
| Condition | Severe Ketamine Use Disorder |
| Key Mechanisms | Ibogaine's NMDA antagonism, kappa opioid receptor agonism, and serotonin transporter inhibition. |
| Target Population | Individuals with severe polysubstance dependence, including ketamine, cocaine, and alcohol. |
| Care Setting | Structured residential treatment program. |
Key Highlights
- Patient achieved immediate cessation of cravings for all substances post-ibogaine treatment.
- Sustained abstinence documented over 17 months with serial toxicology and psychometric assessments.
- Significant improvements in depression and quality of life metrics were observed.
- Ibogaine's unique pharmacology may facilitate long-term behavioral changes.
- First longitudinally documented case of sustained abstinence in severe ketamine use disorder following ibogaine treatment.
Guideline-Based Recommendations
Diagnosis
- Assessment of substance use disorders, including ketamine dependence and comorbid psychiatric conditions.
Management
- Consider ibogaine-assisted treatment within a structured program for severe ketamine use disorder.
Monitoring & Follow-up
- Continuous medical and ECG monitoring during ibogaine administration.
Risks
- Potential safety risks associated with ibogaine, including QT-interval prolongation and neurotoxicity.
Patient & Prescribing Data
30-year-old male with a five-year history of severe polysubstance dependence.
Ibogaine treatment involved an 800 mg flood dose followed by booster doses, leading to significant clinical improvements.
Clinical Best Practices
- Implement structured treatment programs for substance use disorders.
- Utilize continuous monitoring during ibogaine administration to mitigate risks.
- Incorporate psychosocial support alongside pharmacological interventions.
