spirapril and Asthma

Twenty-one subjects with known bronchial hyperreactivity were prospectively randomized in double-blind fashion to receive one of two angiotensin-converting enzyme inhibitors (ACE-I), enalapril or spirapril, for three weeks. Spirometry and methacholine provocation were performed prior to, during, and following ACE-I usage. Three of 21 subjects developed a nonproductive cough. However, only one subject wheezed slightly. Spirometry and bronchial reactivity (PD20) were unchanged throughout the study.
