Azatadine Maleate/Pseudoephedrine Sulfate Repetabs versus Placebo in the Treatment of Severe Seasonal Allergic Rhinitis

Abstract

The symptoms of seasonal allergic rhinitis can be alleviated by the use of an antihistamine and a decongestant. The efficacy and safety of the combination of azatadine maleate and pseudoephedrine sulfate were examined in this double-blind study comparing active drug to placebo. While 74% of the patients administered the combination drug showed marked improvement in the signs and symptoms of seasonal allergic rhinitis, only 29% of patients receiving placebo demonstrated improvement. Adverse reactions were mild and transient.
