BackgroundAcute otitis media (AOM) is very common in children. In spite of spontaneously relief, some cases suffer from the recurrence and other complications occurring after AOM. Animal studies have proved that persistence of leukotrienes in the middle ear may play a role in the development of AOM. Based on this statement, treatment with leukotriene modifiers may be effective in the treatment ...

INTRODUCTION Ureteral obstruction is a common pathology and caused kidney fibrosis and dysfunction at late period. In this present, we investigated the antifibrotic and antiinflammatory effects of montelukast which is cysteinyl leukotriene receptor antagonist, on kidney damage after unilateral ureteral obstruction(UUO) in rats. MATERIALS AND METHODS 32 rats divided four groups. Group 1 was co...

A 16-year-old Caucasian female presented to the pulmonary clinic for a followup on her asthma. Due to the worsening of allergy-related symptoms, therapy with montelukast 10 mg daily was started and resulted in good relief of the patient's symptoms. In the nights following initiating therapy with montelukast, the patient's mother reported daily parasomnias in the form of sleeptalking and sleepwa...

According to published in vitro studies, cytochrome P450 3A4 catalyzes montelukast 21-hydroxylation (M5 formation), whereas CYP2C9 catalyzes 36-hydroxylation (M6), the primary step in the main metabolic pathway of montelukast. However, montelukast is a selective competitive CYP2C8 inhibitor, and our recent in vivo studies suggest that CYP2C8 is involved in its metabolism. We therefore reevaluat...

BACKGROUND Persistent allergic rhinitis often impairs quality of life. OBJECTIVE We assessed the extent to which treating persistent allergic rhinitis with montelukast, desloratadine, and levocetirizine alone or in combination improved quality of life. METHODS A 32-week randomized, double-blind, placebo-controlled, crossover study was performed in 2 arms: 20 patients received montelukast 10...

OBJECTIVE To evaluate the effects on signs and symptoms of a coexisting vernal keratoconjunctivitis in patients treated with oral montelukast sodium for asthma. METHODS Twelve patients with vernal keratoconjunctivitis and asthma were enrolled in this pilot study. Topical eyedrops or any systemic treatment was discontinued for at least 7 days before montelukast treatment. Patients were asked t...
