[On the eventual psychotropic, cardiovascular and aphrodisiac properties of yohimbine, an old drug with new indications].

The authors examined pharmacological actions of Yohimbine, an indolic alkaloid alpha-2-adrenoceptor antagonist. Several specific functions have been attributed to the alpha-2-adrenoceptor such as reduction of sympathetic outflow and pre-synaptic inhibition of noradrenergic neurons. Particularly the following are discussed: behavioural, antidepressant and anxiogenic effects: aphrodisiac effect; cardiovascular effects and metabolic effects.
