๐ฌ Pharmacology (PK/PD)
Pharmacokinetics
How It Works
Levocetirizine is a selective peripheral H1 receptor antagonist. It binds to histamine H1 receptors, preventing histamine from exerting its effects. Histamine is released from mast cells and basophils during allergic reactions, causing vasodilation, increased vascular permeability, and stimulation of sensory nerve endings leading to itching and sneezing. By blocking H1 receptors, levocetirizine reduces these symptoms. It has minimal central nervous system penetration, resulting in lower sedation compared to first-generation antihistamines.
