Guanfacine hydrochloride, a centrally acting anti-hypertensive agent, has been reported to be a specific α2A-AR adrenoceptor agonist. Activation of these α2A-AR adrenoreceptors has been shown to cause a decrease in blood pressure in vitro. Additional studies suggest that Guanfacine hydrochloride plays a role in solute/sodium osmoregulation and excretion.
