title: Bronchodilating effect of terbutaline aerosol.
abstract: We compared the efficacy of terbutaline with that of metaproterenol, isoproterenol, and placebo aerosols in 16 asthmatic patients. Terbutaline, metaproterenol, and isoproterenol produced equivalent improvements in flow rates. At 5 hr, the effect of terbutaline on tests of small airways, FEF25%--75%, and FEF50%, was greater (p less than 0.05) than that of metaproterenol and isoproterenol. Terbutaline produced no significant change of heart rate or blood pressure.
