Mechanism of action

Guanfacine selectively binds to alpha-2A adrenergic receptors in the brain, particularly in the prefrontal cortex, which decreases norepinephrine signaling and enhances working memory and executive function. The sustained-release formulation provides continuous receptor activation over 24 hours, allowing once-daily dosing. This mechanism makes it effective for attention-deficit/hyperactivity disorder (ADHD) and related conditions involving executive dysfunction.
