<unk>  is an antagonist at three of the histamine receptors (1, 2 and 4). The main indication for<unk>  is for prevention of allergic conjunctivitis. By blocking these three receptors,<unk>  has been shown to significantly reduce the effects of allergens. This effect on histamine receptors seems to show lower rates of itching, eosinophil recruitment and redness after exposure to an allergen. The effect of<unk>  seemed to reduce the amount of eosinophil cells significantly as compared to olopatadine 0.1%. When animal models were used to test<unk> ,<unk>  0.25% seemed to show superior results for decreasing E-cadherin expression as compared to placebo. The reduction of E-cadherin means decreased junctions which would lead to progression of allergic conjunctivitis.
