Sixty children were recruited in a 2-stage, randomized, placebo-controlled trial. All patients complained of chronic nasal obstruction symptoms, and nasal endoscopy showed >75% choanal obstruction attributable to adenoid pads. In the first stage, 30 patients (group A) underwent mometasone treatment (50 microg per nostril per day) for 40 days, and 30 children (group B) received placebo. In the second stage, at the end of the first 40-day treatment period, patients in group A who showed subjective and objective clinical improvement were divided into 2 subgroups; group A1 (11 children) received topical intranasal steroid treatment on alternate days for the first 2 weeks per month, whereas group A2 (10 children) continued daily mometasone treatment for the first 2 weeks per month. After 3 months, all children were reassessed.
Seven hundred and twenty (720) patients 3 to 11 years of age with allergic rhinitis were treated with mometasone furoate nasal spray, 50 mcg (100 mcg total daily dose) in controlled clinical trials (see CLINICAL PHARMACOLOGY, Clinical Studies section). Twenty-eight (28) patients 2 to 5 years of age with allergic rhinitis were treated with mometasone furoate nasal spray, 50 mcg (100 mcg total daily dose) in a controlled trial to evaluate safety (see CLINICAL PHARMACOLOGY, Pharmacokinetics section). Safety and effectiveness in children less than 2 years of age with allergic rhinitis and in children less than 18 years of age with nasal polyps have not been established.
