Research of toxicity and pharmacokinetic properties of ibogaine and noribogaine

Ibogaine is a psychoactive alkaloid extracted from the Tabernanthe Iboga Baill. (Apocynaceae). This alkaloid reduces dependence on opiates and attenuates withdrawal symptoms. Ibogaine is metabolized to metabolite – noribogaine. Noribogaine appears less likely to produce the adverse effects associated with ibogaine. The aim of work is to test the toxicity and pharmacokinetic properties of ibogaine and noribogaine by conducting tests with white laboratory mice. The objectives of the research work are as follows: To determine the toxicity of ibogaine and noribogaine by calculating the median lethal dose (LD50) in laboratory mice. To adapt and validate the methodology of high-performance liquid chromatography (HPLC) for the analysis of ibogaine and noribogaine in the blood plasma and internal organs of laboratory mice. To determine ibogaine and noribogaine in plasma and organs of mice. To determine pharmacokinetic parameters of ibogaine and noribogaine in mice blood plasma and organs. To test the influence of repeated doses of ibogaine and noribogaine on the accumulation of these substances in organs of mice. Pharmacokinetic properties reveal quantitative variation of ibogaine and noribogaine in the body, influencing the effectiveness of biologically active substances. Accumulation test of these substances helps to assess the risk of toxicity. The obtained results are useful and informative in order to continue to carry out clinical trials with humans
