PLAY. Synthesis of Leukotrienes •Leukotrienes are synthesized from arachidonic acid, a fatty acid found in membrane phospholipids-Arachidonic acid is released from phospholipids by phospholipase A2 Several studies have shown that the anti-leukotriene drugs diminish the bronchoconstrictor response in patients with aspirin-sensitive asthma. Steroid sparing effect In a randomised, double-blind, placebo-controlled trial of 79 patients with asthma requiring inhaled beclomethasone (1500 microgram daily or more), the inhaled dose of beclomethasone dipropionate was halved. Anti-leukotrienes, including montelukast (Singulair), are administered orally and offer a potential significant advantage over inhaled medications in the pediatric population.8 First introduced in 1996, anti-leukotrienes were the first new class of asthma medication in two decades.
Anti-leukotrienes belong to the first new class of anti-asthma drugs to be intro-duced for over 30 years and have there-fore attracted enormous interest among the clinical community. Asthma is a global disease problem and has be-come the most common chronic dis-ease in industrialized countries. Anti-leukotrienes aredrugs that block the Anti-leukotrienes and ICS also improved lung function and asthma control. However, we are not sure whether the combination of anti-leukotrienes and ICS is superior to higher-dose ICS. Limited available evidence does not support use of anti-leukotrienes as a way to decrease ICS dose. Fingerprint Dive into the research topics of 'Anti-leukotrienes for asthma'.

Cysteinyl leukotrienes (cLTs) contribute to the pathogenesis of asthma and other allergic disorders, and participate in the development of airway inflammation 1., 2•.. In the past 5 years, the advent of drugs that interfere with the production or action of cLTs has led to important changes in asthma management [3••] . 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. And for people with allergies, anti-histamines play a key role in alleviating symptoms. But for people with asthma, important mediators include prostaglandin D 2, platelet activating factor, leukotrienes and other chemicals involved in inflammation. The mediators that may play the most critical role are leukotrienes.
Leukotrienes … Antileukotrienes represent a new class of anti-asthma drugs with anti-inflammatory role.

Other names: antileukotrienes, leukotriene receptor antagonists, leukotriene synthesis zafirlukast, and zileuton may be considered for the treatment of asthma. Leukotriene antagonists, also known as antileukotrienes, are drugs that inhibit leukotrienes.
