Several reports suggest the presence of isoenzymes of LTA4hydrolase [ 39, Leukotriene-receptor antagonists, such as montelukast and zafirlukast, prevent leukotrienes from binding to their receptors Leukotriene synthesis inhibitors, such as zileuton, block the enzyme, 5-lipoxygenase, which is necessary for the formation of leukotrienes. Montelukast, zafirlukast, and zileuton may be considered for the treatment of asthma.

The formation of leukotrienes through the 5-lipoxygenase pathway depends on lipoxygenation of arachidonic acid, a major constituent of cell membrane phospholipids, detached by phospholipase A 2 activity. Leukotrienes (LTs) are important mediators of the pathophysiology of asthma, specifically, bronchoconstriction, airway inflammation and oedema and mucus hypersecretion. The LT receptor antagonists (LTRAs) inhibit these potent effects by selectively blocking the cysteinyl LT 1 receptor. Leukotriene modifier medications work by blocking the actions of leukotrienes in the body.
