It has been proven as an effective medication to reduce both systolic and diastolic blood pressure via its effect on Alpha-2 adrenergic autoreceptors. Prolonged-action guanfacine (Intuniv—Shire Pharmaceuticals Ltd) is a non-stimulant drug that has recently been licensed in Europe for the management of attention deficit hyperactivity disorder (ADHD) in children and adolescents aged 6–17 years for whom stimulants are unsuitable.1 The company suggests that it has a unique mechanism of action in ADHD, providing improvement in core symptoms Guanfacine is a selective α2A‐adrenoceptor agonist (Arnsten et al., 2007). A long‐acting formulation (guanfacine extended release; GXR) is approved for children and adolescents in the United States and Canada. 2019-03-11 · PubMed PubMed Central Google Scholar 35.

Overall, 694/1177 (59.0%) participants in the guanfacine group benefited from the treatment compared to 192/575 (33.3%) in the placebo group (pooled OR 3.2; 95%CI 2.4-4.1). This phase 3 trial evaluated the safety and efficacy of guanfacine extended release (GXR) in adolescents with ADHD. Method: This 13-week, multicenter, randomized, double-blind, placebo-controlled trial evaluated once-daily GXR (1-7 mg per day) in adolescents with ADHD aged 13 to 17 years. 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. 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. Abstract.
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.
Publication types Abstract. 1 Guanfacine 3-6 mg daily lowered blood pressure in five essential hypertensives and also reduced saliva production.. 2 Plasma and urinary noradrenaline values were significantly reduced throughout the 8-10 weeks of treatment.. 3 On substitution of placebo tablets for guanfacine, blood pressure increased over a 2-4d period to reach but did not significantly exceed pretreatment levels.
Guanfacine extended release met the primary and secondary efficacy end points. It was well tolerated and effective compared with placebo.

This short acting form of guanfacine has been used clinically (“off-label”) for the treatment of ADHD in typical developing children and for treating inattention and hyperactivity in PDDs (Posey and McDougle 2007). Guanfacine, a noradrenergic alpha2a agonist, reduced tobacco smoking in a 4-week trial and in animal models has been shown to reduce cortical dopamine release, which is critically involved in the

All studies compared guanfacine versus placebo, with a duration ranging from 6 to 16 weeks. In all, the Clinical Global Impression Improvement score was reported as a secondary measure. Overall, 694/1177 (59.0%) participants in the guanfacine group benefited from the treatment compared to 192/575 (33.3%) in the placebo group (pooled OR 3.2; 95%CI 2.4-4.1).
