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.

Guanfacine is a centrally acting adrenergic agonist with non-stimulant and antihypertensive property. Guanfacine selectively stimulates alpha-2 adrenergic receptors in the central nervous system, thereby resulting in inhibition of sympathetic nervous system outflow. 2020-10-02 Abstract. 1 Total body clearance and renal clearance after single intravenous doses of guanfacine were 360 ± 262 (mean ± s.d.) and 233 ± 245 ml/min, respectively, in patients with normal renal function (glomerular filtration rate (GFR) > 90 ml/min), 308 ± 274 and 34 ± 22 ml/min, respectively, in patients with moderately impaired renal function (GFR 30-10 ml/min), and 257 ± 187 and 18 Guanfacine extended release is a selective α 2-adrenergic receptor agonist, directly stimulating postsynaptic α 2A-adrenergic receptors to enhance noradrenaline neurotransmission. 12 In the United States and Canada, GXR is approved for use in children and adolescents as monotherapy or adjunctive to stimulant therapy.

Guanfacine and protriptyline internal standard were extracted from alkalinized urine with ethyl acetate. The organic layer was evaporated, reconstituted with mobile phase and analyzed on a YMC Basic S-5 micron, 2.0 × 150 mm HPLC column connected to an MS detector operated in positive electrospray ionization mode with selected ion resonance. Dose-Optimization in Adolescents Aged 13-17 Diagnosed With Attention-Deficit/ Hyperactivity Disorder (ADHD) Using Extended-Release Guanfacine HCl; Guanfacine extended-release (GXR), a selective α2A-adrenergic agonist, is a non-stimulant treatment for attention-deficit/hyperactivity disorder (ADHD). Guanfacine extended release met the primary and secondary efficacy end points.
Synopsis: Guanfacine,1 a phenylacetyl-guanidine derivative, is a centrally acting α-adrenoceptor agonist, with a mechanism of antihypertensive action similar to that of clonidine. It reduces blood pressure in patients with essential hypertension at least as effectively as clonidine or methyldopa. Like lower doses of clonidine, guanfacine can be given once daily due to its relatively long
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. Guanfacine hydrochloride, USP is a centrally acting antihypertensive with α 2 -adrenoceptor agonist properties in tablet form for oral administration.. The chemical name of guanfacine hydrochloride, USP is N-amidino-2-(2,6-dichlorophenyl) acetamide hydrochloride and its molecular weight is 282.56. Guanfacine extended-release tablets are indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) as monotherapy and as adjunctive therapy to stimulant medications [see 2 DOSAGE AND ADMINISTRATION 2.1 General Instruction for Use - Swallow tablets whole. Guanfacine hydrochloride is an orally active antihypertensive agent whose principal mechanism of action appears to be stimulation of central α2-adrenergic receptors. By stimulating these Guanfacine works in the prefrontal cortex to increase attention and cognition by activating postsynaptic norepinephrine receptors.

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 Guanfacine for the treatment of cognitive disorders: a century of discoveries at Yale.
