A Comparison of Bronchodilator Therapy with or without Inhaled Corticosteroid Therapy for Obstructive Airways Disease

Abstract

The addition of an inhaled corticosteroid--but not an inhaled anticholinergic agent--to maintenance treatment with a beta 2-agonist (terbutaline) substantially reduced morbidity, hyperresponsiveness, and airways obstruction in patients with a spectrum of obstructive airways disease.
