Several drugs are effective in attenuating intestinal ischemia-reperfusion injury (IRI); however little is known about the effect of montelukast. Fifty rats were randomly assigned to 3 groups: model group (operation with clamping), sham group (operation without clamping), and study group (operation with clamping and 0.2, 2 and 20 mg/kg montelukast pretreatment). Intestinal ischemia-reperfusion ...

The prototype cysteinyl leukotriene receptor antagonist, montelukast, is generally considered to have a niche application in the therapy of exercise- and aspirin-induced asthma. It is also used as add-on therapy in patients whose asthma is poorly controlled with inhaled corticosteroid monotherapy, or with the combination of a long-acting beta(2)-agonist and an inhaled corticosteroid. Recently, ...

OBJECTIVE We tested the hypothesis that adding montelukast to budesonide would improve asthma control in children with inhaled glucocorticoid-dependent persistent asthma. STUDY DESIGN In a multicenter, randomized, double-blind, crossover study, we compared the benefit of adding montelukast, 5 mg, or placebo once daily to budesonide, 200 microg, twice daily. RESULTS After a 1-month run-in wi...

RATIONALE Airway inflammation in asthma is accompanied by structural changes, including goblet cell metaplasia, smooth muscle cell layer thickening, and subepithelial fibrosis. This allergen-induced airway remodeling can be replicated in a mouse asthma model. OBJECTIVES The study goal was to determine whether established airway remodeling in a mouse asthma model is reversible by administratio...

OBJECTIVE Montelukast, a selective antagonist of Type 1 cysteinyl leukotriene receptors (CysLT1Rs), antagonizes the proinflammatory and proasthmatic activities of CysLT1Rs. We investigated the effect of montelukast on a surgically induced endometriosis rat model. STUDY DESIGN Thirty-two sexually mature, cycling, female Wistar-Albino rats, in which endometriotic implants were surgically induce...

BACKGROUND AND OBJECTIVE Exercise-induced wheeze (EIW) is common. Several treatment options exist. Patients with low fraction of exhaled nitric oxide (F(E)NO) are unlikely to be steroid-responsive and might benefit from non-steroidal therapies. We assessed: the efficacy of cromoglycate, formoterol and montelukast in patients with EIW and low F(E)NO (<35 ppb) in a randomized cross-over trial, an...

BACKGROUND Budesonide inhalation suspension and the leukotriene receptor antagonist montelukast have demonstrated efficacy in children with mild persistent asthma, but comparative long-term studies in young children are needed. OBJECTIVE To compare the long-term efficacy and safety of budesonide inhalation suspension and montelukast. METHODS After a run-in period, children 2 to 8 years old ...

Bronchiolitis obliterans syndrome (BOS) remains the major problem which precludes long-term survival after lung transplantation. Previously, an open label pilot study from our group demonstrated a possible beneficial effect of montelukast in progressive BOS patients with low airway neutrophilia (<15%), and already on azithromycin treatment, in whom the further decline in pulmonary function was ...

Inflammatory process contributes to progressive lung tissue damage in cystic fibrosis (CF). Cysteinyl leukotrienes have been found in the sputum of CF patients at concentrations sufficient to cause potent biological effect. This study was designed to assess the effect of anti-inflammatory treatment with montelukast sodium in CF patients. Twelve patients, aged 6-29 were recruited. It was 20 week...

The incidence of overlapping bronchial asthma and chronic obstructive pulmonary disease has increased in recent years. Cysteinyl leukotrienes (CysLTs) play an important role in asthma, and the type 1 CysLT receptor (CysLT1R) is expressed by many inflammatory cells. We evaluated the effect of montelukast, a CysLT1R antagonist, on mouse models of asthma, porcine pancreatic elastase (PPE)-induced ...
