简要总结
This active vs active comparative trial will evaluate the safety and efficacy of incremental doses of atropine in combination with pseudoephedrine 120 mg/chlorpheniramine 8 mg in adult patients with a history of seasonal allergic rhinitis. Hypotheses are defined by total nasal symptom scores (TNSS) recorded by subjects in diaries where efficacy will be established by statistical significance where p < 0.05.
