Inhibition by Furosemide of Inflammatory Mediators from Lung Fragments

Abstract
Bianco and colleagues (Oct. 19, 1989, issue)1 reported that furosemide, when given as an aerosol, can prevent the early and late responses induced by allergen. The mechanism whereby furosemide protects the airways in response to allergen challenge could involve the release of inflammatory mediators from lung cells. We report the effect of furosemide on the in vitro release of sulfidopeptide leukotrienes and histamine from human lung tissue passively sensitized to Dermalophagoides pteronyssinus (the house-dust mite). This same allergen was used in 5 of the 11 subjects studied by Bianco et al.1
