- Brief Summary
OBJECTIVES:
I. Evaluate the safety and efficacy of the alpha-2 adrenergic agonist guanfacine in children and adolescents with Tourette syndrome or other chronic tic disorder, and attention deficit hyperactivity disorder.
- Detailed Description
PROTOCOL OUTLINE: This is a randomized, double-blind study. Patients are stratified by pubertal status.
There is a 7- to 14-day washout with a placebo prior to treatment for all patients.
The first group receives oral guanfacine 3 times a day for 8 weeks. The dose is gradually increased to minimize sedation; by day 14, most patients are stabilized and the dose is then increased as clinically indicated and tolerated.
The second group receives a placebo 3 times a day for 8 weeks. Patients in either group may be treated with guanfacine for an additional 8 weeks.
