Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialDouble-blind, placebo-controlled study comparing the efficacy and safety of fexofenadine hydrochloride (120 and 180 mg once daily) and cetirizine in seasonal allergic rhinitis.
Fexofenadine hydrochloride (HCl) is a new H(1) antihistamine used twice daily in some countries. ⋯ Once-daily fexofenadine is thus a valuable addition to the nonsedating group of H(1) receptor antagonists currently available for the treatment of seasonal allergic rhinitis.
