From the Research
Ibogaine does indeed prolong the QT interval, which can be a significant and potentially life-threatening cardiac risk. This effect is supported by the most recent and highest quality study available, which found that ibogaine treatment can induce a clinically relevant but reversible QTc prolongation 1. The study, published in 2022, observed that the maximum QTc prolongation was on average 95ms, with 50% of subjects reaching a QTc of over 500ms during the observation period.
Key Findings
- The QT prolongation effect of ibogaine appears to be dose-dependent and can persist for more than 24 hours after administration due to the drug's long half-life and active metabolites 1.
- The mechanism behind this effect involves ibogaine's interaction with certain potassium channels in heart cells, specifically hERG potassium channels, which are crucial for normal cardiac repolarization 2.
- Individuals with pre-existing heart conditions, electrolyte abnormalities, or those taking other medications that affect the QT interval are at particularly high risk for complications 3.
- Thorough cardiac screening, including baseline ECG, electrolyte testing, and medication review, should be conducted before considering ibogaine treatment 4.
Clinical Implications
- Medical supervision is essential when ibogaine is used in addiction treatment settings due to the cardiac risks associated with QT prolongation 1.
- The use of ibogaine should be approached with caution, and alternative treatments should be considered for individuals with high-risk profiles 5.
- Further research is needed to fully understand the safety and efficacy of ibogaine in the treatment of addiction, particularly in vulnerable populations 5.
