Treatment with desloratadine:

• Inhibition of allergic inflammatory mediators

• Reduces symptoms of nasal obstruction in the well-designed studies

• Improve nasal airflow, an objective measurement of the nasal obstruction

Desloratadine and EAACI/ARIA Criteria for Antihistamines

in Allergic Rhinitis

• AERIUS meets all EAACI-ARIA criteria for antihistamines required for the treatment of allergic rhinitis– Efficacy

• Effective in the treatment of intermittent and persistent rhinitis

• Effective for all nasal symptoms including nasal obstruction

• Improvement of eye symptoms

• Improvement in asthma symptoms

• Efficacy in pediatric and elderly patients

Desloratadine and EAACI/ARIA Criteria for Antihistamines

in Allergic Rhinitis

- Safety and tolerability/side effects• No sedation or cognitive or psychomotor impairment

• No anti-cholinergic effects

• No weight gain

• No cardiac side effects

• Studies should be carried out in young children and elderly patients to assess safety

• Prospective postmarketing safety analysis should be conducted

Efficacy NASONEX in Pediatric Patients with Perennial Allergic Rhinitis

• 4-week, double-blind study (double blind)• With the extension of the 26-week, open-

label• Children 3-11 years• MFNS 100 mcg qd or placebo

Results Clinical Experience NASONEX in Children

• Mometasone furoate nasal spray (MFNS) 100 mcg qd is the optimal dose in children over 2 years

• Low potential for systemic effects• There is no short-term growth disorders• There is no evidence of HPA axis suppression• Well tolerated• Incidence of adverse events similar placebo
