About Clemastine Fumarate
Clemastine fumarate is a strong, long-acting, quick-acting, highly selective histamine H1 receptor antagonist, which simultaneously blocks H1 receptors and antagonizes cytotoxicity. It is mainly used clinically for allergic skin diseases and allergic rhinitis. Such allergic diseases have brought good news to patients who suffer from allergic diseases all year round. “Stins” drugs belong to a strong, long-acting, highly selective histamine H1 receptor blocker, and have no inhibitory effect on the cholinergic effect of the central nervous system, no sedation and lethargy. They are mostly used Allergic rhinitis, anti-allergy asthma, urticaria, eczema, dermatitis and skin pruritus.
