TY - JOUR T1 - A comparison of the effect of ipratropium and albuterol in the treatment of chronic obstructive airway disease AU - Braun SR, McKenzie WN, Copeland C, Knight L, Ellersieck M Y1 - 1989/03/01 N1 - 10.1001/archinte.1989.00390030044008 JO - Archives of Internal Medicine SP - 544 EP - 547 VL - 149 IS - 3 N2 - • Twenty-five subjects with moderate to severe chronic obstructive airway disease were studied to compare the effect of ipratropium bromide, albuterol, and placebo on the forced expiratory volume in 1 s, (FEV1), forced vital capacity, heart rate, and blood pressure during six hours. Ipratropium produced a significantly greater improvement than albuterol in the FEV1 at 30 minutes and at 3, 4, and 5 hours and in the forced vital capacity at one through six hours. Fifteen subjects did not demonstrate a 15% improvement and at least a 200-mL increase in the FEV1 15 minutes after metaproterenol sulfate aerosol. All 15 did improve after ipratropium therapy during the study. Ipratropium was effective significantly longer than albuterol. Subjects with better peak responses to ipratropium had a lower FEV1 percent predicted and a greater pack-year smoking history. In patients with chronic obstructive airway disease, ipratropium produces a longer duration of action than albuterol. It is more effective than albuterol in treating severely obstructed individuals and those not responding to metaproterenol. It is equally effective in treating others.(Arch Intern Med 1989;149:544-547) SN - 0003-9926 M3 - doi: 10.1001/archinte.1989.00390030044008 UR - http://dx.doi.org/10.1001/archinte.1989.00390030044008 ER -
