what is guanfacine for
Guanfacine (brand name Estulic, Tenex and the extended release Intuniv) is a sympatholytic drug used in the treatment of attention deficit hyperactivity disorder (ADHD), anxiety and hypertension (not to be confused with guaifenesin, an expectorant). It is a selective Î±2A receptor agonist.
Treatment of withdrawal syndrome[edit] Guanfacine is also being investigated for treatment of withdrawal for opioids, ethanol, and nicotine. Guanfacine has been shown to help reduce stress-induced craving of nicotine in smokers trying to quit, which may involve strengthening of prefrontal cortical self-control.
Am Fam Physician. 2011 Feb 15;83(4):468-475. Guanfacine (Intuniv) is an extended-release, nonâcentral nervous system stimulant approved for the treatment of attention-deficit/hyperactivity disorder (ADHD) in children six to 17 years of age; however, it appears to be most effective in children 12 years or younger.
