目的：了解丙卡特罗扩张支气管的作用时间。方法：支气管哮喘１４５例（男性８７例，年龄４１±ｓ１４ａ，女性５８例，年龄３９±２０ａ），口服丙卡特罗５０μｇ，每２ｈ测定最大呼气流速（ＰＥＦ）值。结果：服药后４ｈ和１２ｈ改善呼吸困难的总有效率为８７．５％和６６．１％，改善哮鸣音的总有效率为９４．７％和８１．３％，△ＰＥＦ％≥１５％者７４．５％和３２．４％。结论：丙卡特罗作用时间可达１２ｈ。
Objective: To understand the role of procaterol bronchodilator expansion time. METHODS: A total of 145 patients with bronchial asthma (87 males, age 41 ± s14a, 58 females, age 39 ± 20a) were given oral procaterol 50 μg and the maximum expiratory flow (PEF) was measured every 2 hours. Results: The total effective rate of improving dyspnea was 87.5% and 66.1% at 4h and 12h, the total effective rate of improving wheeze was 94.7% and 81.3%, △ PEF% ≥15% 74.5% and 32.4% respectively. Conclusion: Procaterol time of up to 12h.
