The effect of 60 mg twice-daily fexofenadine HCl on health-related quality of life and productivity at work, in the classroom, and during daily activities in patients with moderate to severe chronic idiopathic urticaria symptoms was studied in two identical, 4-week, placebo-controlled, multicenter clinical trials. Patients self-administered the Dermatology(More)
Fluticasone propionate (FP) administered via metered-dose inhaler is a potent corticosteroid effective in the treatment of asthma. To evaluate the efficacy and safety of FP powder administered via a breath-activated inhaler (Diskhaler), a multicenter, double-blind, randomized, placebo-controlled, parallel-group study was conducted in adolescent and adult(More)
BACKGROUND H1-receptor antagonists are effective for the treatment of seasonal allergic rhinitis. In rare circumstances, some second-generation H1-receptor antagonists have been associated with prolongation of the corrected QT interval (QTc), thus increasing the risk of ventricular arrhythmias. Fexofendine HCl, the carboxylic acid metabolite of terfenadine,(More)
This multicenter, double-blind, randomized, controlled, parallel-group study compared the safety and efficacy of intranasal triamcinolone acetonide with oral loratadine in relieving symptoms of ragweed-induced seasonal allergic rhinitis. Patients from community-based allergy practices with a history of at least two seasons of seasonal allergic rhinitis(More)
Allergic rhinitis can be a debilitating condition which, if untreated, can result in considerable health-related and economic consequences. A review of the published literature was conducted, with quantitative/qualitative analysis as appropriate, to explore the direct, indirect, and hidden costs of allergic rhinitis, as well as the quality-of-life burdens(More)
The efficacy of terfenadine, a nonsedating H1 antihistamine, in the management of chronic idiopathic urticaria was compared with chlorpheniramine and placebo in a parallel multicenter trial. Subjects with symptoms of hives for 3 days per week for at least 6 weeks were initially screened and admitted if no identifiable cause for symptoms could be determined.(More)
Establishing a reliable estimate of the prevalence of allergic rhinitis is difficult; prevalence estimates range from as low as 4% to more than 40%. Epidemiology studies suggest the prevalence of allergic rhinitis in the United States and around the world is increasing. The cause of this increase is unknown; however, contributing factors may include higher(More)
Because biological indicators alone do not adequately represent the comprehensive health status of a patient with asthma, we also assessed patients' health-related quality of life (HRQOL) in a randomized, double-blind, placebo-controlled study of the effects of the inhaled corticosteroid fluticasone propionate (FP). A total of 342 patients with moderate(More)
