A multicentered trial compared the effects of the non-sedating antihistamine, loratadine, 5 mg plus pseudoephedrine 120 mg with a placebo on the signs and symptoms of the common cold. One hundred forty-two (142) subjects were treated with the loratadine/pseudoephedrine combination and 141 subjects were treated with placebo twice daily for five days. Evaluations by both subjects and physicians suggest that this antihistamine/decongestant combination is superior to placebo in relieving symptoms of the common cold. Specific differences were found in symptoms including nasal congestion, sneezing, postnasal drainage, and nasal discharge. Differences between groups for the following side effects were found: dry mouth (9% for the combination vs 2% for placebo), insomnia (6% vs 3%), and nervousness (4% vs 2%). There were no differences between groups for the frequency of drowsiness.

The efficacy and safety of an extended-release combination of loratadine plus pseudoephedrine sulfate (SCH 434) was compared with that of a tablet containing chlorpheniramine maleate plus pseudoephedrine sulfate (CTM-D) in 131 patients with symptomatic seasonal allergic rhinitis. Patients were randomly assigned to receive either SCH 434 (loratadine 5 mg and pseudoephedrine sulfate 120 mg) or CTM-D (chlorpheniramine maleate 12 mg and pseudoephedrine sulfate 120 mg) twice daily for 2 weeks. Evaluations were made after 3, 7, and 14 days of treatment. Demographics (age, race, sex, and duration of seasonal allergic rhinitis) and baseline total symptom scores were comparable between groups. Both combination products were effective in relieving the symptoms of allergic rhinitis. Improvement in total symptom scores was 54% on day 3 and 65% on day 14 in the SCH 434 group versus 57% on day 3 and 64% on day 14 in the CTM-D group. Individual symptom scores (nasal discharge, stuffiness, nasal itching, sneezing, and ocular symptoms) responded similarly. A smaller proportion of patients in the SCH 434 group reported side effects, especially dry mouth (7% vs 19%, P = 0.07), fatigue (6% vs 25%, P < 0.01), and sedation (7% vs 22%, P < 0.03). In conclusion, the combination of loratadine plus pseudoephedrine sulfate was equally as effective as a classic antihistamine (chlorpheniramine maleate) plus pseudoephedrine sulfate but had a lower incidence of side effects.

396 adult and adolescent patients with seasonal allergic rhinitis participated in this randomised double-blind parallel-group study in which the efficacy and tolerability of ebastine 10 or 20mg administered once daily in the morning or evening for 3 weeks were compared with those of placebo. Clinical efficacy was assessed by measuring improvement in rhinitis symptoms (nasal discharge, nasal stuffiness, sneezing, itchy nose and itchy/watery eyes) recorded by patients twice daily on diary cards. The improvement in individual and total symptom scores at the end of the 3-week treatment period in patients treated with ebastine 10mg in the morning or ebastine 20mg in the morning or evening was significantly greater than the improvement in placebo recipients. The 20mg dose of ebastine administered in the morning was associated with the greatest improvement in symptom scores. There was no significant effect with the 10mg evening dose compared with placebo. Ebastine was well tolerated by the majority of patients - the incidence of adverse events, including headache, dry mouth, somnolence and asthenia being similar to that reported in placebo recipients. Electrocardiograms showed no evidence of any clinically relevant changes in QTc intervals. In a subsequent nonblinded 4-month study that included 230 patients from the initial study, global evaluations at monthly intervals showed overall symptom improvement in > or = 72% of patients who received ebastine 10mg or 20mg once daily. The drug was well tolerated during prolonged therapy, with adverse events being similar in nature and incidence to those reported in the 3-week double-blind study. In conclusion, ebastine 10mg once daily in the morning is an appropriate starting dose for the treatment of rhinitis, and this can be increased to 20mg as required.
