Homochlorcyclizine (INN) is an antihistamine which has been marketed in Japan since 1965. It is used in the treatment of Itching sensation resulting from skin diseases (eczema or dermatitis, pruritus, drug eruption, toxic erythema and infant strophulus), urticaria and allergic rhinitis. Homochlorcyclizine hydrochloride possesses several pharmacological properties: 1) inhibits bradykinin-induced contractions of isolated guinea pig ileum; 2)partially blocks SRS-A (slow-reacting substance of anaphylaxis )- induced contractions in isolated guinea pig il eum. 3) Homochlorcyclizine hydrochloride completely inhibits histamine-induced contractions at a concentration of 0.1μg/mL, while it completely inhibits serotonin or acetylcholine- induced contractions at a concentration of 1μg/mL.
