Allergic rhinitis in family practice: the role of levocetirizine in clinical care
Abstract
Allergic rhinitis is one of the most common presentations of allergic disorders in the United States, affecting more than 20% of the population. Chronic rhinitis affects patients' quality of life and exacerbates comorbid conditions. Its widespread burden affects society by substantially decreasing worker and scholastic productivity. Allergic rhinitis is typically managed with pharmacotherapy to alleviate symptoms and control comorbid conditions, yet many of these agents carry their own burden due to bothersome and sometimes severe side effects that can compromise patient safety. A new generation of non- or less-sedating antihistamines has recently emerged. These agents offer the promise of enhanced efficacy and tolerability. Of these agents, levocetirizine is the latest antihistamine introduced in the United States. It appears to be safe and effective for the treatment of allergic rhinitis. In addition to covering the above topics, this article reviews the value of levocetirizine for the treatment of allergic rhinitis based on its pharmacologic and pharmacokinetic profile, its efficacy compared with placebo and other new-generation antihistamines, and its safety and tolerability.
