A total of 317 patients received loratadine, 10 mg once daily, terfenadine 60 mg twice daily, or placebo in a 14-day, double-blind, randomized study in seasonal allergic rhinitis. Four nasal and four nonnasal symptoms were evaluated. At the end point evaluation, mean total scores of combined nasal and nonnasal symptoms decreased from baseline (improved) 46%, 44%, and 35%, respectively, for loratadine, terfenadine, and placebo. The difference between loratadine and placebo treatment was significant (p = 0.03). Loratadine was particularly effective compared with placebo in relieving nasal discharge, sneezing, and itching/burning eyes. Therapeutic response to treatment was good or excellent in 66 (64%) of 103 loratadine-treated patients, 58 (56%) of 104 terfenadine-treated patients, and 48 (47%) of 102 placebo-treated patients. Adverse experiences reported during the study were usually mild or moderate and were not significantly different among the three treatment groups. Sedation (somnolence) was reported by 10 loratadine-treated patients, seven terfenadine-treated patients, and eight placebo-treated patients. Loratadine, 10 mg once daily, was comparable to terfenadine, 60 mg twice daily, and significantly superior to placebo in the symptomatic relief of seasonal allergic rhinitis.

Limited data support the use of first-generation antihistamines for treatment of the common cold. The purpose of this study was to test the effectiveness of clemastine fumarate, a first-generation antihistamine, for treatment of sneezing and rhinorrhea associated with naturally occurring common colds. Four hundred three subjects (202 clemastine fumarate recipients and 201 placebo recipients) who reported new onset (< 24 hours) of cold symptoms that included rhinorrhea or sneezing were studied. At baseline (day 1), the mean symptom-severity scores +/- SEM for the clemastine fumarate and placebo groups were not significantly different. The mean rhinorrhea-severity score +/- SEM was not different on day 2; however, on day 3, the mean rhinorrhea-severity score +/- SEM was 1.02 +/- 0.07 for the clemastine fumarate group and 1.39 +/- 0.07 for the placebo group (P < .001). This treatment effect persisted on day 4. A significant effect on sneezing was noted on days 2-4. Sedation occurred in 14% of the clemastine fumarate-treated subjects and 1.5% of the placebo-treated subjects (P < .0001).
