Guanfacine is an α2A-adrenoreceptor agonist currently indicated for the treatment of attention deficit hyperactivity disorder (ADHD). This article reviews the chemistry, pharmacodynamics and pharmacokinetics of guanfacine, as well as the clinical trial literature on guanfacine for the treatment of ADHD in children and adolescents, mainly focusing on the use of guanfacine extended-release (GXR).
Objective: This is a feasibility study evaluating the safety, tolerability, and potential anxiolytic efficacy of the α 2 agonist guanfacine extended-release (GXR) in children and adolescents with generalized anxiety disorder (GAD), separation anxiety disorder (SAD), or social phobia/social anxiety disorder. Methods: Youth aged 6-17 years with a primary diagnosis of GAD, SAD, and/or social 2 Guanfacine induced a decrease in plasma noradrenaline concentration and plasma renin activity concomitant with a fall in blood pressure and heart rate in both the acute and the chronic study. 3 The adrenergic response to upright posture, reflected by an increase in plasma noradrenaline concentration and plasma renin activity, was not abolished after chronic guanfacine therapy.

Guanfacine tablets are an orally active antihypertensive agent whose principal mechanism of action appears to be stimulation of central α2-adrenergic receptors. By stimulating these receptors
The chemical name of guanfacine hydrochloride is N-Amidino-2-(2,6-dichlorophenyl) acetamide monohydrochloride and its molecular weight is 282.55. Guanfacine (marketed under the brand names Estulic, Tenex and the extended release Intuniv) is a sympatholytic drug, indicated for the management of hypertension.

However, in abrupt withdrawal blood pressure returned to the pretreatment level over a 2-4d period. This review concluded that guanfacine extended release appeared to be more efficacious than atomoxetine for the treatment of attention deficit hyperactivity disorder in children and adolescents. Concerns about the reporting, the limited number of trials, and the validity of the statistical analysis, mean that these results should be interpreted with caution. Guanfacine Hydrochloride is the hydrochloride salt form of guanfacine, a centrally acting alpha-2 adrenergic agonist with antihypertensive activity. Alpha-2 receptor stimulation by guanfacine hydrochloride results in a decreased sympathetic outflow from the vasomotor center to the heart, kidneys, and peripheral vasculature. Guanfacine (GUAN) was approved for children and adolescents (6–17 years) in Japan in May 2017.
Alpha-2 receptor stimulation by guanfacine hydrochloride results in a decreased sympathetic outflow from the vasomotor center to the heart, kidneys, and peripheral vasculature. Guanfacine (GUAN) was approved for children and adolescents (6–17 years) in Japan in May 2017. Orally administered GUAN is rapidly and completely absorbed, with maximum plasma concentrations occurring 1–4 h after administration [ 20 ]. Guanfacine extended-release (GXR) is a nonstimulant, selective, α2A-adrenergic receptor agonist approved worldwide for ADHD in children and adolescents and was first approved for treatment of ADHD in adults in Japan in June 2019.

Cardiac output and pulmonary arterial pressure were determined by the Swan-Ganz thermodilution method. Blood pressure was measured directly. Guanfacine immediate release (IR) is FDA approved to treat hypertension in adolescents and adults.
This review report was prepared by the Canadian Agency for Drugs and Technologies in Health (CADTH). In addition to CADTH staff, the review team included a clinical expert in pediatrics who provided input on the conduct of the review and the interpretation of findings. OBJECTIVE: In this post hoc analysis, we assessed whether guanfacine extended-release (GXR) adjunctive to a psychostimulant resulted in greater response and remission 5Guanfacine is an effective antihypertensive drug with a spectrum of actions similar to clonidine.
