A single oral dose of ibogaine (1 or 20 mg/kg body weight) in rats did not alter the activities of superoxide dismutases, catalase, glutathione peroxidase, glutathione reductase, or glutathione-S-transferase in the liver or erythrocytes at 6 or 24 hours after administration. However, hepatic xanthine oxidase activity increased in rats receiving 20 mg/kg, indicating faster adenosine turnover. TBARS concentration rose in the 1 mg/kg group after 24 hours, suggesting mild oxidative stress. Histological examination revealed glycogenolytic activity in hepatocytes, peaking at 24 hours in the higher-dose group. Ibogaine influenced hepatic redox homeostasis but not enough to remodel antioxidant enzyme activities within the timeframe studied.

A single oral dose of ibogaine (1 or 20 mg/kg body weight) in rats altered kidney antioxidant enzyme activities and caused mild morphological changes without affecting overall kidney function. The lower dose increased superoxide dismutase 1 activity and decreased glutathione reductase activity at 6 and 24 hours; the higher dose also decreased glutathione reductase activity, indicating disrupted redox balance. After 24 hours, moderate structural changes in kidney tissue were observed, but urinalyses showed no impairment of kidney function. The authors advise monitoring kidney function during and after ibogaine use in humans.

A single oral dose of ibogaine (20 mg/kg) in female Wistar rats caused transient oxidative stress in the brain and depleted glycogen stores in the liver. Six hours after treatment, lipid peroxidation (TBARS) increased significantly, while after 24 hours it returned to control levels. Protein free sulfhydryl groups increased, but nonprotein free sulfhydryl groups (indicating reduced glutathione) decreased, both more pronounced at 24 hours. Despite these signs of oxidative stress, the activities of antioxidative enzymes (SOD, CAT, GSH-Px, GR) and glutathione S-transferases remained unchanged. Liver glycogen was reduced, more at 6 hours than at 24 hours, suggesting a transient depletion of energy reserves that begins to recover within a day. These findings suggest ibogaine induces rapid, reversible changes in redox and energy homeostasis.
