This effect can increase sympathetic outflow and potentiate the release of norepinephrine from nerve endings, leading to activation of 1 and 1 receptors in the heart and peripheral vasculature, with a consequent rise in blood pressure Blocks presynaptic 2 adrenergic receptors Indications: Rarely used Sometimes used in the treatment of orthostatic hypotension because it promotes norepinephrine release through blockade of 2 receptors in both the central nervous system and the periphery There is some evidence that it may be possibly effective in treating erectile dysfunction & SSRI related sexual dysfunction in both men & women by unclear mechanisms (NIH Medlineplus) Has been suggested to have aphrodisiac properties Side Effects: Yohimbine exerts a stimulating action on the mood and may increase anxiety Major drug Interactions: Yohimbine can reverse the antihypertensive effects of an 2 receptor agonist such as clonidine, a potentially serious adverse drug interaction References: Biaggioni I (2021): Adrenoceptor Antagonists (Chapter 10)
