Levocetirizine Dihydrochloride: A New Histamine H1 Antagonist with a Superior Affinity for H1 Receptors over Its Racemate, Cetirizine [C2316]

Levocetirizine dihydrochloride is a new second-generation histamine H1 antagonist, developed from cetirizine [C2316]. Chemically, levocetirizine is the active R-enantiomer of cetirizine. Levocetirizine has a superior affinity and selectivity for H1 receptors over racemic cetirizine or the S-enantiomer, and has a favorable pharmacokinetic profile.
