Atopy, Chronic Idiopathic Urticaria
Conditions
Brief summary
This study was conducted to evaluate the safety and tolerance of desloratadine after 5 weeks of repetitive dosing in children ages 2 to 12 years old with allergic hypersensitivity or chronic hives. All of the subjects enrolled in this trial were previously identified in an earlier trial to be poor metabolizers of desloratadine.
Interventions
desloratadine syrup: 1.25 mg (2.5 mL) for subjects \>=2 to \<6 years, 2.5 mg (5 mL) for subjects \>=6 to \<12 years, orally once daily in the morning for 36 days.
placebo syrup: 2.5 mL for subjects \>=2 to \<6 years, 5 mL for subjects \>=6 to \<12 years, orally once daily in the morning for 36 days.
