Leukotrienes are inflammatory mediators, derived from arachidonic acid, in whose presence occurs increased vascular permeability in tissues, leading to inflammatory processes.
The presence of leukotrienes has been related to the development of allergic reactions, mainly in the respiratory tract, producing edema in the mucosa, contraction of the smooth muscles of the airways and increased production of mucus
in the airways.

- <em>Are related to the production of bronchial asthma.

- <em>Are inflammatory (chemical) mediators. </em>
