Abstract
GARZA-BELTRAN, Marco Antonio et al. Efficacy and Safety of Fixed-Dose Combination of Montelukast-Desloratadine 10 mg/5 mg Capsule in Mexican Adults with Persistent Allergic Rhinitis: A Double-Blind, Randomized, Controlled, and Multicenter Study. Rev. am. med. respir. [online]. 2023, vol.23, n.1, pp.76-84. ISSN 1852-236X. http://dx.doi.org/10.56538/ramr.dicz6213.
Objective:
The objective of the present study was to evaluate the efficacy and safety of the fixed dose combination of montelukast/desloratadine 10 mg/5 mg capsule versus the combination of montelukast/loratadine 10 mg/10 mg tablet in adults diagnosed with persistent allergic rhinitis.
Materials and methods:
The present study was a multicenter, controlled, prospective, longitudinal, randomized, double-blind clinical trial with parallel arms. Patients diagnosed with persistent allergic rhinitis who met eligibility criteria and signed informed consent were enrolled in the study to receive one of the two treatments every 24 hours orally for 6 weeks. Efficacy was established by clinical evaluation through clinical scales vali dated in Spanish, being the primary efficacy variable the difference in the score of the SNOT-20 (Sino-Nasal Outcome Test) questionnaire at the end of treatment; and the frequency and characteristics of adverse events were considered the safety variable.
Results:
86 patients were randomized, 74 of which were analyzed per protocol. Ques tionnaires about the symptoms of the disease and quality of life indicators with both treatments showed that more than 90% of patients had mild symptoms or no symptoms at all at the end of the study. So, both treatments significantly improved (p < 0.05) the symptoms of the disease. Adverse events were mild to moderate.
Conclusions:
The present study showed that the efficacy of montelukast/desloratadine 10 mg/5 mg is not inferior to the comparator. Therefore, the study treatment represents an effective and safe alternative for the second-line treatment of persistent allergic rhinitis in patients in whom monotherapies or first-line treatments don’t offer clinically relevant improvement.
