Introduction: Bepotastine besilate 1.5% is a newly approved second-generation topical antihistamine indicated for the pruritus associated with allergic conjunctivitis. In Japan, the oral formulation is approved to manage pruritus associated with allergic rhinitis and urticaria.
Areas Covered: Bepotastine is a piperidine derivative that antagonizes H1 receptors with high selectivity. It has been labeled a dual-acting or multiple-acting antiallergic medication, because it inhibits histamine at H1 receptors and stabilizes mast cells to prevent histamine release. Bepotastine may also have other immunoactive properties, such as inhibition of eosinophil migration, interleukin-5 (IL-5), leukotrienes (e.g., LTB4) and platelet-activating factor (PAF). Human clinical trials demonstrate the efficacy and safety of systemic and ophthalmic bepotastine for pruritus relief, limited penetration across the blood-brain-barrier and kinetics suitable for twice-daily administration.
Expert Opinion: Bepotastine besilate 1.5% ophthalmic solution is a safe and effective treatment option for allergic conjunctivitis associated pruritus. Side-effect profile is similar to other ocular antihistamine agents. Additional comparative-effectiveness studies would further advance its clinical use. Oral bepotastine is a safe and effective treatment option approved in Japan for allergic rhinitis, urticaria and pruritus associated with skin diseases.

Background: Rituximab, an anti-CD20 monoclonal antibody, can cause infusion reactions (IRs), especially during the initial rituximab infusion therapy. Generally, patients are administered a histamine H-receptor antagonist before the rituximab infusion, along with an antipyretic analgesic, to prevent or reduce IRs. Multiple retrospective case-control studies indicate that the second generation of histamine H-receptor antagonists might be more effective than the first generation in suppressing IRs caused by the rituximab infusion.

Background Urticaria is a common skin disease which often causes impairment in the quality of life. The ideal drug for chronic urticaria would have antihistaminic and anti-inflammatory actions. Bepotastine besilate is a recently approved novel anti-allergic agent with multiple mechanisms of action; levocetirizine is a potent and selective second-generation H1 receptor antagonist used in the treatment of urticaria.

Article Synopsis
- Chronic urticaria is a common skin condition that causes discomfort, and there is a need for more effective treatment options like bepotastine, a second-generation antihistamine that may also help reduce eosinophil migration.
- A study was conducted to compare the effectiveness and safety of bepotastine and levocetirizine in treating chronic urticaria, involving adult patients randomly assigned to either medication over multiple follow-ups.
- Results showed that both medications reduced urticaria severity scores, but bepotastine had a significantly lower incidence of daytime sedation compared to levocetirizine, suggesting it might be a better option for patients concerned about side effects.
