    Abstract:
    BACKGROUND: Bepotastine besilate is a selective histamine1-receptor antagonist and mast cell stabilizer with inhibitory effects on eosinophilic activity. OBJECTIVE: To evaluate the safety and efficacy of 1.5% bepotastine besilate ophthalmic solution in alleviating nonocular symptoms induced by a conjunctival allergen challenge (CAC), a clinical model of allergic conjunctivitis. METHODS: This was a single-center, double-masked, randomized, placebo-controlled clinical trial performed from March 1 to April 4, 2007. Patients 10 years or older with a history of allergic conjunctivitis and a reproducible, positive, clinical response to a CAC were eligible. Patients received either placebo or 1.5% bepotastine besilate, 1 drop in each eye. After 15 minutes, 8 hours, or 16 hours after dosing, a CAC was performed and patients evaluated nonocular symptoms using standardized grading scales. RESULTS: Seventy-one patients were enrolled in the study, and 66 comprised the per protocol population. A clinically meaningful reduction (> or = 1.0 unit) compared to placebo was achieved for rhinorrhea and nasal congestion at most time points after 1.5% bepotastine besilate instillation at 8 hours before a CAC test. Significant reductions (P < or = .05) in mean values were seen with 1.5% bepotastine besilate at 15 minutes and 8 hours after dosing for CAC-induced nasal congestion, rhinorrhea, ear or palate pruritus, nasal pruritus, and summed nonocular composite symptom (NOCS) scores and also at 16 hours after dosing for nasal congestion and rhinorrhea. CONCLUSIONS: The 1.5% bepotastine besilate formulation produced statistically significant reductions after a CAC in individual nonocular symptoms and NOCS scores at onset of allergic response and for at least 8 hours after instillation, with the greatest reduction seen for nasal congestion and rhinorrhea.
