Placebo Controlled Pilot Study on the Efficacy of Levocetirizine 5 mg in Reducing Symptoms, Airway Resistance, and Sleep Impairment in Patients With Persistent Allergic Rhinitis
Abstract
The purpose of this study is to investigate, whether levocetirizine 5 mg relieves nasal and ocular symptoms of persistent allergic rhinitis and reduces increased airway resistance and sleep impairment due to this condition.
Conditions: Allergic Rhinitis.
Primary outcome: Average T5SS calculated with respect to the 8 week treatment period. T5SS is the daily sum of 4-step symptom scores, which patients use to report the severity of five symptoms of allergic rhinoconjunctivitis in their diaries..
Enrollment: 100 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 100 participants or records.
