Yohimbine is a plant alkaloid with alpha-2-adrenergic blocking activity. Yohimbine has been used as a mydriatic and in the treatment of impotence. The exact mechanism for its use in impotence has not been fully elucidated. Yohimbine exerts antagonist actions at halpha(2A)-AR, h5-HT(1B), h5-HT(1D), and hD(2) sites, partial agonist actions at h5-HT(1A) sites. Yohimbine-mediated norepinephrine release at the level of the corporeal tissues may also be involved. In addition, beneficial effects may involve other neurotransmitters such as dopamine and serotonin and cholinergic receptors. Yohimbine has a mild anti-diuretic action, probably via stimulation of hypothalmic center and release of posterior pituitary hormone. Reportedly yohimbine exerts no significant influence on cardiac stimulation and other effects mediated by (beta)-adrenergic receptors. Its effect on blood pressure, if any, would be to lower it; however, no adequate studies are at hand to quantitate this effect in terms of Yohimbine dosage. Side effect of Yohimbine include anxiety, tremor, palpitations, diarrhea, and supine hypertension.

Sample Use Guides
2 single-dose administrations of 5 mg yohimbine hydrochloride at least one week i.e. 6 treatment free days between all administrations
Route of Administration:
Oral
In order to test the putative role of alpha 2 receptors in ethanol intoxication, it was studied the interaction between ethanol and yohimbine on the spontaneous firing rate of rat locus coeruleus (LC) in an in vitro slice model. If yohimbine (20 microM) was simultaneously perfused, the ethanol-induced inhibition was rapidly antagonized. This effect is reversible after long time washout of yohimbine.
