Comparison of the efficacy, safety and quality of life provided by fexofenadine hydrochloride 120 mg, loratadine 10 mg and placebo administered once daily for the treatment of seasonal allergic rhinitis

BACKGROUND: As there have been no previously published studies, this multinational, double-blind, randomized, placebo-controlled, parallel group study compared the efficacy, safety and impact on quality of life (QoL) in seasonal allergic rhinitis patients (SAR) of fexofenadine and loratadine (with placebo), when administered once daily. METHODS: Six hundred and eighty-eight SAR patients were randomized to receive fexofenadine HCl 120 mg, loratadine 10 mg or placebo, once daily for 2 weeks. The key parameters were the change from baseline in: mean 24-h reflective total symptom scores (TSS); sum of four individual symptom scores, excluding nasal congestion; instantaneous TSS; individual symptom scores including nasal congestion; and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ). Adverse events were recorded. RESULTS: Mean 24-h reflective and instantaneous TSS were significantly reduced by both fexofenadine HCl (both P
