Persistent allergic rhinitis (RAP) manifests symptoms frequently and constantly. The current treatment of RAP with antihistamines and antileukotrienes is recommended as second- line treatment for the relief of the symptoms of the disease. Therefore, the objective of the present study was to compare the efficacy and safety of the combination of montelukast / desloratadine (MKDES) versus the combination of montelukast / loratadine (MKLOR) in adults with a diagnosis of RAP. The present was a multicenter, controlled, prospective, longitudinal, randomized, double-blind clinical study, with two parallel arms of active treatment (MKDES 10/5 mg vs MKLOR 10/10 mg) every 24 hours orally for 6 weeks.
