依美斯汀 (Emadine)

概览

Emedastine is a selective H1-receptor antagonist used topically to manage symptoms of allergic conjunctivitis.

作用机制

Emedastine is a relatively selective, histamine H antagonist. In vitro examinations of emedastine's affinity for histamine receptors demonstrate relative selectivity for the H histamine receptor. In vivo studies have shown concentration-dependent inhibition of histamine-stimulated vascular permeability in the conjunctiva following topical ocular administration. Emedastine appears exert negligible effects on adrenergic, dopaminergic and serotonin receptors.

适应症

For the temporary relief of the signs and symptoms of allergic conjunctivitis.

• Allergic Conjunctivitis (AC)
