Comparison of efficacy, safety, and cost-effectiveness of montelukast-levocetirizine and montelukast-fexofenadine in patients of allergic rhinitis: A randomized, double-blind clinical trial
Abstract
OBJECTIVES: Allergic rhinitis (AR) is a global health problem. Almost 10%-25% of population worldwide is affected by AR. Oral/intranasal H1-antihistamine, decongestants, leukotriene receptor antagonists, and intranasal corticosteroids are the pillars in the management of AR. The combination therapy of montelukast with antihistaminic provides enhancing and complimentary effects, thereby reducing the symptoms effectively, but there are scanty data regarding the comparisons of combinations. Therefore, we aimed to compare the efficacy, safety, and cost-effectiveness of montelukast-levocetirizine and montelukast-fexofenadine combination in patients of AR.
MATERIALS AND METHODS: Seventy patients with AR participated in a prospective, randomized, double-blind, parallel, active-controlled, comparative 4-week trial. The patients between the age group of 18-65 years of either gender having moderate-severe intermittent or mild persistent AR were included in the study. The study inclusion criteria required the patients with total nasal symptom score (TNSS) of 5 or higher. The patients were randomly divided into two treatment groups with montelukast-levocetirizine (10 mg and 5 mg) in one group and montelukast-fexofenadine (10 mg and 120 mg) in another group. TNSS parameter was the main effectiveness parameter.
RESULTS: Evaluation of TNSS revealed significant difference (P < 0.05) when compared from baseline to 4th week in both groups. The mean change of TNSS, i.e., 9.46 was significant…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
