Notes: Alcaftadine is a potent antagonist of the H1 histamine receptor (IC50 = 8.6 nM) with lower affinities for the H2 and H4 receptors (IC50s = 62 nM and 4.4 μM, respectively).{34359} This antiallergenic agent has anti-inflammatory and mast cell stabilizing effects.{34330} Alcaftadine has been shown to reduce edema and erythema in a guinea pig model of allergic conjunctivitis (ED50 = 0.1 mg/kg) more effectively than ketotifen (Item No. 20303) (ED50 = 1.0 mg/kg) and has been used in clinical formulations in eye drops for treatment of ocular itching associated with allergic conjunctivitis.{34359,34360} Alcaftadine also binds to 5-HT2A and 5-HT2C receptors (Kis = 2.5 and 1.5 μM, respectively).{34359}
