Use of ipratropium bromide in patients with severe airways obstruction. R. J. Pierce, P. W. Holmes and A, H. Campbell, Aust. N.Z. J. Med., 1982, 12, pp. 38–43. In ten adult patients with severe, partially reversible airflow obstruction due to asthma, with or without co‐existent chronic bronchitis, the acute bronchodilator responses of ipratropium bromide (40 fig) and terbutaline (500 fig) from metered‐dose inhalers, atropine methonitrate (2 mg) as a wet aerosol and placebo were compared in a double blind trial. Also the combination of ipratropium bromide and terbutaline aerosols was compared with both ipratropium and terbutaline alone in short‐term and long‐term studies. In the short‐term study, all the drugs produced significant bronchodilatation compared with placebo. The responses to ipratropium bromide and terbutaline alone were not significantly different. The combination of ipratropium bromide with terbutaline did not produce significantly greater changes in the FEV U SGaw or static lung volume than terbutaline alone. Atropine methonitrate however, produced significantly greater changes of the airway conductance (SGaw) and static lung volumes (TLC and RV) but not FEV, when compared to ipratropium bromide. When administered over randomised periods of one month each there were no significant differences between the combination of ipratropium bromide and terbutaline and each drug alone in daily airflometer recordings, daily symptom scores or fort‐ nightly spirometry and clinical assessment. It is concluded that ipratropium bromide, in the conventional dose of 40 pgm by metered‐ dose inhaler produces safe, effective broncho‐dilatation. Its effect, however, did not significantly augment that of the fl adrenergic stimulant, terbutaline and was less than that of atropine methonitrate 2 mg by wet aerosol.
