Description
Epinastine Hydrochloride is an histamine H1 receptor antagonist without sedative activity. Epinastine hydrochloride blocks the histamine H1 receptor and inhibits the release of histamine from mast cells. This prevents the typical allergic symptoms that are caused by histamine activity on capillaries, skin, mucous membranes, and on gastrointestinal and bronchial smooth muscles. Typical histamine activities include vasodilation, bronchoconstriction, increased vascular permeability, pain, itching, and spasmodic contractions of gastrointestinal smooth muscles. Epinastine also has affinity for the histamine H2, 5-HT2, and the alpha-1, alpha-2 adrenergic receptors.
EPINASTINE HYDROCHLORIDE is a small molecule drug with a maximum clinical trial phase of IV that was first approved in 2003 and is indicated for allergic conjunctivitis.

7.1 MeSH Pharmacological Classification

Histamine H1 Antagonists
Drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine. Included here are the classical antihistaminics that antagonize or prevent the action of histamine mainly in immediate hypersensitivity. They act in the bronchi, capillaries, and some other smooth muscles, and are used to prevent or allay motion sickness, seasonal rhinitis, and allergic dermatitis and to induce somnolence. The effects of blocking central nervous system H1 receptors are not as well understood. (See all compounds classified as Histamine H1 Antagonists.)
