Indication For the relief of symptoms associated with seasonal allergic rhinitis and chronic idiopathic urticaria.
Pharmacology Astemizole, an H1-receptor antagonist, is similar in structure to terfenadine and haloperidol, a butyrophenone antipsychotic. It has anticholinergic (atropine-like) and antipruritic effects.
Mechanism of Action Astemizole competes with histamine for binding at H1-receptor sites in the GI tract, uterus, large blood vessels, and bronchial muscle. This reversible binding of astemizole 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 and preferentially binds at H1 receptors in the peripehery rather than within the brain, CNS depression is minimal. Astemizole may also act on H3-receptors, producing adverse effects.
Absorption Rapidly absorbed from the gastrointestinal tract.
Toxicity LD50=2052mg/kg in mice
Protein Binding 96.7%
Biotransformation Almost completely metabolized in the liver and primarily excreted in the feces.
Half Life 1 day
