Levocetirizine Drug

Tablets Capsule Injection Birth Control Device Ointments Syrups

Levocetrizine or levocetirizine is a selective, long acting peripheral H1 receptor antagonist antihistamine. The increased polarity of the drug may decrease distribution of the drug into the CNS, resulting in reduced potential for adverse CNS effects. Tolerance does not occur. As it does not readily cross the blood brain barrier, it does not cause sedation or interfere with mental alertness or memory function.



The drug is highly effective and well-tolerated anti-histamine, introduced for treating symptoms associated with seasonal allergic rhinitis, perennial allergic rhinitis and chronic idiopathic urticaria.

Levocetrizine, a potent single isomer of cetrizine, binds twice as strongly to histamine H1 receptors in vitro and also has a highly consistent and predictable anti-histamine action.
