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.

Chronic ITP results in increased destruction of inadequate production of platelets in the blood, creating an increased risk of bruising and bleeding.

The FDA granted Promacta orphan drug designation in May 2008 and accelerated approval in November 2008.
