Leukotrienes (LTs) C 4, D 4, and E 4, collectively termed cysteinyl LTs (cysLTs), are lipid mediators formed by the 5-lipoxygenase (5-LO) pathway of
Antileukotrienes (ALT) or leukotrienes antagonists (LA) is a new class of anti-asthma drugs with anti-inflammatory role
Antileukotriene agents, which can be used in treatment of allergen and exercise-induced asthma and allergic rhinitis, inhibit 5-lipoxygenase or the binding of the activator protein with 5-lipoxygenase or antagonists of leukotriene receptors at the target cell (e
Leukotrienes are biologically active eicosanoid lipid mediators that originate from oxidative metabolism of arachidonic acid
One of the randomized, placebo controlled trials and one nonrandomized trial was with montelukast

Curr Opin Allergy Clin Immunol 2017 , 17:131–138 ICS: aeroallergen sensitivity, blood eosinophil >= 300/mL are predictors of good response to daily ICS LTRA Recent studies- no clear benefit, WAIT trial - identified a genotype that may increase response
Beyond literature, Vidal was heavily involved in LTA 4 Note the four double bonds, three of them conjugated
Background: In the treatment of children with mild persistent asthma, low-dose inhaled corticosteroids (ICS) are recommended as the preferred monotherapy (referred to as step 2 of therapy)

Anti-leukotriene therapy is a novel, specific anti-asthma strategy providing both reliever and controller effects
Leukotrienes (LTs), including LTB (4) and cysteinyl-LTs (CysLTs) (LTC (4), LTD (4), and LTE (4)), are potent inflammatory lipid mediators which are derived from 5-lipoxygenase activity
Cysteinyl leukotrienes (Cys-LTs) are potent proinflammatory mediators derived from arachidonic acid through the 5-lypoxigenase (5-LO) pathway
Patients with inadequate asthma control are often treated by adding an anti-leukotriene (LTRA) or a long-acting β 2-agonist, or by increasing the dose of ICS
, neutrophil recruitment Antileukotriene receptor antagonists (LTR As) bind competitively to cysteinyl leukotriene receptors 1 and block the contractile promoting activity of leukotrienes in airway smooth muscles
Inhaled glucocorticoids are the cornerstone of asthma management because of their efficacy, tolerance, and relatively rapid onset of action compared with other anti-inflammatory drugs
The review suggests that anti-leukotrienes are safe, but less effective than a low dose of inhaled corticosteroids
