Intuniv OKed as add-on therapy to treat ADHD

PHILADELPHIA — The Food and Drug Administration has approved a new use for a Shire drug to treat attention deficit hyperactivity disorder, Shire said Monday.

The FDA approved Intuniv (guanfacine) as an add-on therapy for children and adolescents already taking stimulants to treat ADHD, also known as an adjunctive therapy.

The approval was based on a nine-week placebo-controlled study of the drug in which children and adolescents received it in combination with a stimulant.
