Levocabastine Hydrochloride is the hydrochloride salt form of levocabastine, a synthetic piperidine derivative with antihistaminic properties. Levocabastine is a second generation histamine-1 receptor antagonist. When applied locally to the eye as a topical solution, this agent reduces itching, rhinorrhea, and symptoms of allergic rhinitis or conjunctivitis.

4.1 MeSH Pharmacological Classification

Histamine H1 Antagonists, Non-Sedating

A class of non-sedating drugs that bind to but do not activate histamine receptors (DRUG INVERSE AGONISM), thereby blocking the actions of histamine or histamine agonists. These antihistamines represent a heterogenous group of compounds with differing chemical structures, adverse effects, distribution, and metabolism. Compared to the early (first generation) antihistamines, these non-sedating antihistamines have greater receptor specificity, lower penetration of BLOOD-BRAIN BARRIER, and are less likely to cause drowsiness or psychomotor impairment. (See all compounds classified as Histamine H1 Antagonists, Non-Sedating.)
