Evaluation of effectiveness of rupatadine and olopatadine in patients of allergic rhinitis at Indore: a randomized control trial

摘要

Background: Allergic rhinitis (AR) is one of the most prevalent atopic disorders that affect productivity and quality of life. Although individually olopatadine and rupatadine are efficacious in AR, data on the head to head study of these drugs in Indian population are scanty, so present study was undertaken with an aim to compare the efficacy, safety, and cost effectiveness of rupatadine and olopatadine in patients’ of allergic rhinitis. Methods: A prospective, randomized, double blind, parallel group, comparative 2 weeks clinical study conducted in eighty patients of AR in the Department of Pharmacology, Index Medical College Hospital and Research Centre, Indore. Following inclusion and exclusion criteria, 67 patients were recruited and randomized to two treatment groups and received the respective drugs for 2 weeks. At follow-up, parameters assessed were total nasal symptom score (TNSS), change in total and differential count of eosinophil. Results: In olopatadine group, there was a significantly higher reduction in TNSS (P < 0.05) than that of rupatadine. Both the drugs significantly reduced the absolute eosinophil count, but olopatadine (P <0.001) was found to be superior. The incidence of adverse effects was found to be less in olopatadine group when compared with rupatadine group. Conclusions: Both rupatadine and olopatadine provide effective relief of the symptoms of AR. However, clinical benefit occurs significantly more with olopatadine. However, rupatadine was more cost?effective than olopatadine in treating the patients of AR in term of effectiveness.
