What is Guanfacine
A centrally acting antihypertensive agent. The drug lowers both systolic and diastolic blood pressure by activating the central nervous system alpha-2 adrenoreceptors, which results in reduced sympathetic outflow leading to reduced vascular tone. Its adverse reactions include dry mouth, sedation, and constipation. (PubChem)
Guanfacine mechanism of action
Guanfacine selectively stimulates central alpha(2)-adrenergic receptors, resulting in inhibition of sympathetic vasomotor centers, which contributes predominantly to the hypotensive effects of the drug. Central effects of guanfacine lead to reduced peripheral sympathetic nerve impulses from the vasomotor center to the heart and blood vessels. This results in a decrease in peripheral vascular resistance and a reduction in heart rate. The stimulation of peripheral alpha(2)-adrenergic receptors may also contribute to hypotensive effects.
