Efficacy of oral bilastine monotherapy versus oral probiotics in patients with allergic rhinitis: An observational comparative study

Introduction

Allergic rhinitis (AR) is among the most common chronic disorders encountered in otorhinolaryngology practice, and pharmacotherapy with second-generation oral antihistamines remains the mainstay of symptomatic treatment. Study aimed to compare the efficacy of oral bilastine monotherapy versus oral probiotics in patients with allergic rhinitis over 4 weeks of treatment, with change in Total Nasal Symptom Score (TNSS) from baseline as the primary endpoint and change in Absolute Eosinophil Count (AEC) from baseline as the secondary endpoint.
