Leukotrienes in asthma These cysteinyl leukotrienes, previously known as the slow-reacting substance of anaphylaxis (SRS-A), mediate many of the features of asthma, including bronchial constriction, bronchial mediators in asthma, making them obvious targets for therapy. These cysteinyl leukotrienes, previously known as the slow-reacting substance of anaphylaxis (SRS-A), mediate many of the features of asthma, including bronchial constriction, bronchial hyperreactivity, edema, and eo-sinophilia. To determine the pathogenetic role of leukotrienes in chronic airway diseases, sputum samples from patients with bronchial asthma (BA), diffuse panbronchiolitis (DPB), sinobronchial syndrome (SBS), and bronchiectasis (BE) were examined for the presence of leukotrienes (LT) C4, D4, E4, B4, all apparently derived from airway inflammatory cells.

Drug Interactions: Leukotrienes play a central pathophysiological role in asthma [1–4,6], particularly in specific subgroups of patients with asthma. Cysteinyl-LTs induce pathophysiological responses similar to those associated with asthma and elevated cysteinyl-LT concentrations have been detected in biological However, most people with persistent asthma also need an inhaled corticosteroid or other long-term control medication. If you need to use your inhaler more often than your doctor recommends, your asthma is not under control — and you may be increasing your risk of a serious asthma attack.

Leukotrienes are very important agents in the inflammatory response. Some such as LTB 4 have a chemotactic effect on migrating neutrophils, and as such help to bring the necessary cells to the tissue. Leukotrienes also have a powerful effect in bronchoconstriction and increase vascular permeability. Leukotrienes in asthma

They are formed partly by allergic reactions and partly by a large number of other more non-specific reactions.
