This active component competes with endogenous histamine for binding at peripheral H1-receptor sites. It prevents the negative symptoms related to histamine release and an allergic reaction. It plays a vital role in angiogenesis during an allergic inflammatory reaction that blocks the action of histamine that may modulate the expression of proangiogenic factors.
