Most of the pharmacological work on voacorine and voacamine has focused on their cardiotonic properties. Voacamine shows little tendency to accumulate, and is less toxic than cardiac glycosides such as digitoxin. In high doses both are hypertensive due largely to peripheral vasoconstriction. Both compounds also have parasympatholytic and sympatholytic properties, bringing about contraction of smooth muscle fibres. Both of the alkaloids, plus affinine, are also central nervous system depressants[

At low doses, ibogaine exerts primarily a stimulant effect, increasing alertness and reducing fatigue, hunger and thirst. At higher doses, the primary effects are hallucinations. Apart from the psychological effects, the physical effects include tremor, light sensitivity, nausea, vomiting, and loss of coordination. Toxic doses produce convulsions, paralysis and death from respiratory arrest although the heart continues to beat. Ibogaine is also a potent cholinesterase inhibitor[
