Terfenadine is an antihistamine for the treatment of allergy symptoms.
Terfenadine competes with histamine for binding at H1-receptor sites in the GI tract, uterus, large blood vessels, and bronchial muscle. This reversible binding of terfenadine to H1-receptors suppresses the formation of edema, flare, and pruritus resulting from histaminic activity. As the drug does not readily cross the blood-brain barrier, CNS depression is minimal.
For the treatment of allergic rhinitis, hay fever, and allergic skin disorders.
