Abstract

Based upon pharmacokinetic and phase 1 studies, the novel antihistamine alcaftadine is an appropriate drug for use as an ophthalmic formulation for prevention and treatment of ocular allergic conditions such as allergic conjunctivitis (alcaftadine ophthalmic solution 0.25% was recently approved for use by the FDA). Topical administration of alcaftadine 0.25% ophthalmic solution was well tolerated and had an acceptable safety profile.
