Intuniv XR 2 mg (Guanfacine (Guanfacine Hydrochloride) TABLET (EXTENDED-RELEASE)) 2 MG

Intuniv XR 2 mg is primarily used to manage symptoms of attention deficit hyperactivity disorder (ADHD) in children and adolescents. It is also used off-label for the treatment of hypertension.

• ADHD: Helps improve attention, reduce hyperactivity, and control impulsivity in children and adolescents with ADHD.
• Hypertension: May be used to lower blood pressure, though this is an off-label use.
• As adjunctive therapy: Can be used alongside psychostimulants for ADHD treatment in patients who do not respond adequately to other non-stimulant alternatives.
• Monotherapy: May be used as a single therapy for patients who cannot tolerate psychostimulants or have had an inadequate response to other non-stimulant treatments.

• Guanfacine works by selectively activating post-synaptic alpha-2A adrenergic receptors in the prefrontal cortex. This action decreases sympathetic outflow and enhances attention and impulse control. By modulating these receptors, guanfacine helps to strengthen working memory, reduce distraction, and improve overall focus and behavior in individuals with ADHD.
