右溴苯那敏 (Ala-hist Ir, Ala-hist PE, Dologen +1)

概览

Dexbrompheniramine is an antihistamine used to treat allergy symptoms including upper respiratory tract symptoms.

作用机制

Dexbrompheniramine competitively binds to the histamine H-receptor. It competes with histamine for the normal H-receptor sites on effector cells of the gastrointestinal tract, blood vessels and respiratory tract. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.

适应症

• Allergic Rhinitis (AR)
• Upper respiratory tract hypersensitivity reaction, site unspecified
