描述 | Guanfacine hydrochloride, an anti-hypertensive agent. Extended-release guanfacine appears to be safe and effective for reducing hyperactivity, impulsiveness, and distractibility in children with ASD (autism spectrum disorder)[3]. Guanfacine lowers blood pressure by activating CNS alpha adrenoreceptors, which results in sympathetic outflow leading to reduced vascular tone. Guanfacine is rapidly and completely absorbed from the gastrointestinal tract and apparently undergoes extensive distribution to all tissues. Guanfacine's adverse reactions include dry mouth, sedation, and constipation. Adverse effects and reaction to sudden withdrawal of the drug may be less severe with guanfacine than with clonidine[4]. Guanfacine extended release (ER), as a new option to the treatment of attention deficit hyperactivity disorder, which acts at postsynaptic level. Guanfacine stimulates postsynaptic alfa-2A adrenergic receptors so it inhibits the production of cAMP and closes HCN channels enhancing the effectiveness of the signal of the pyramidal neurons of the prefrontal cortex, thus improving working memory and attention[5]. |
