It was approved by the U.S. Food and Drug Administration in 2010 under the trade name Lastacaft. Alcaftadine is an antagonist at three of the histamine receptors (1, 2 and 4). The main indication for Alcaftadine is for prevention of allergic conjunctivitis. By blocking these four receptors, Alcaftadine has been shown to significantly reduce the effects of allergens.
