In a May 29, 2007 press release, sanofi-aventis and UCB announced that the FDA approved Xyzal® (active ingredient: levocetirizine dihydrochloride) a once-daily prescription antihistamine for the relief of seasonal and perennial allergic rhinitis, as well as for the treatment of chronic idiopathic urticaria (hives) in adults and in children age six and older. UCB filed the new drug application (NDA) in July 2006 and researched the drug in a number of clinical trials. Xyzal® was shown to reduce the severity of common symptoms associated with allergies, such as runny nose, itchy eyes, and sneezing. In patients with hives, the drug was able to reduce the number, size, and itch associated with the hives.
In the fall of 2006, sanofi-aventis signed an agreement with UCB in which it agreed to launch and co-market and Xyzal®, which is expected to be ready for launch for the upcoming fall allergy season.
