Isr Med Assoc J. 2008 Apr;10(4):287-91 Authors: Amirav I BACKGROUND: Based on the outcome of several randomized controlled trials, the orally active leukotriene receptor antagonist montelukast (Singulair, Merck) has been licensed for treatment of asthma. The drug is favored for treating childhood asthma, where a therapeutic challenge has arisen due to poor compliance with inhalation therapy. OBJECTIVES: To assess the efficiency of and satisfaction with Singulair in asthmatic children under real-life conditions. METHODS: Montelukast was prescribed for 6 weeks to a cohort of 506 children aged 2 to 18 years with mild to moderate persistent asthma, who were enrolled by 200 primary care pediatricians countrywide.
