OBJECTIVE: In this post hoc analysis, we assessed whether guanfacine extended-release (GXR) adjunctive to a psychostimulant resulted in greater response and remission 5Guanfacine is an effective antihypertensive drug with a spectrum of actions similar to clonidine. However, in abrupt withdrawal blood pressure returned to the pretreatment level over a 2-4d period. This review concluded that guanfacine extended release appeared to be more efficacious than atomoxetine for the treatment of attention deficit hyperactivity disorder in children and adolescents. Concerns about the reporting, the limited number of trials, and the validity of the statistical analysis, mean that these results should be interpreted with caution. Guanfacine Hydrochloride is the hydrochloride salt form of guanfacine, a centrally acting alpha-2 adrenergic agonist with antihypertensive activity.
