Summary
Ibogaine shows promise as a treatment for drug dependence, but understanding its pharmacokinetics has been challenging due to limited analytical methods. A new technique utilizing gas chromatography and methane chemical ionization mass spectrometry allows for precise measurement of ibogaine levels in plasma. This method requires just one milliliter of plasma and employs a synthesized internal standard, [13C2H3]Ibogaine, to ensure accurate recovery during preparation. This advancement enhances the ability to quantify ibogaine, potentially paving the way for more effective treatments.
Abstract
Ibogaine is naturally occurring indole alkaloid that is currently being considered as a treatment medication for drug dependence. Although there have been a variety of investigations regarding the mechanisms of action and pharmacology of ibogaine, relatively little has been reported regarding quantitative methods. Because of the paucity of analytical methodologies, studies involving the pharmacokinetics and metabolism of ibogaine have also been limited. A method is described for the determination of ibogaine levels in plasma by gas chromatography -- methane chemical ionization mass spectrometry. [13C2H3]Ibogaine was synthesized and used as an internal standard to control for recovery during sample preparation. The assay requires one ml of plasma and is shown to be a selective and sensitive means of ibogaine quantitation.
