Epinastine (E6055-GRP)

Epinastine (WAL801) is potent nonsedative antiallergic agent and an antagonist of histamine H1 receptor. It inhibits the actions of leukotrienes, platelet-activating factor (PAF), and bradykinin. It also stabilizes mast cells and reduces IL-8 release from eosinophils, helping to control allergic inflammation.
