Treatment of chronic urticaria with a beta2-adrenergic stimulant

Twenty-four patients with chronic utricaria resistant to conventional therapy were treated orally with terbutaline, a specific beta2 stimulant. This therapy was much more effective than antihistamines. At the dose of 1-25 mg three times a day, there were few side effects. The efficacy was independent of the IgE levels; it seemed greater in idiopathic cases than in cholinergic or pressure induced urticaria.
