Structure
Astemizole Chemical Structure - C28H31FN4O
Mode of action
Histamine and Astemizole compete for binding to H1-receptor locations in the GI tract, uterus, major blood arteries, and bronchial muscle.
Astemizole reversible binding to H1-receptors prevents edema, flare, and pruritus from developing because of histaminic action.
Uses
Astemizole is prescribed to treat allergic issues that occur in runny noses, itchy, watery eyes, skin rashes, and allergic reactions to foods and medications.
