Guanfacine, a phenylacetyl-guanidine derivative, is a centrally acting alpha-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 lowe …

Results were then limited to criteria such as English and human, from 1990 through December 2011. 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.

Results EMA authorisation of guanfacine is based upon clinical trials conducted by manufacturer Shire. Guanfacine is considered safe and effective for long-term monotherapy treatment for up to 24-months, demonstrating efficacy in improving ADHD symptoms with mild adverse effects. Side-effects include sedation, hypotension and bradycardia.

Guanfacine is a centrally acting alpha‐2 adrenergic agonist. The absolute bioavailability, pharmacokinetics, and renal clearance of this antihypertensive drug were investigated in healthy male volunteers. Eighteen subjects received a single oral or intravenous dose of guanfacine 3 mg in a two‐way cross‐over study design.

The resulting yield from the comprehensive literature … 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. All studies compared guanfacine versus placebo, with a duration ranging from 6 to 16 weeks.

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. 17 In Europe, GXR is approved for the treatment of children and adolescents The objective of this review was to compare the clinical benefits and harms of guanfacine extended release (GXR; PubMed Health.

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. Tenex (guanfacine hydrochloride) is an orally active antihypertensive agent whose principal mechanism of action appears to be stimulation of central α2-adrenergic receptors. 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. 17 In Europe, GXR is approved for the treatment of children and adolescents 5 Guanfacine caused a significant decrease in plasma noradrenaline and adrenaline, suggesting a decrease in sympatho-adrenal activity.
