General description

Ketotifen fumarate salt is an antihistamine drug.

Application

Ketotifen fumarate salt has been used: for mast cell product antagonism, as a positive control in β-hexosaminidase release assay, as mast cell stabilizer to treat pregnant dams added to ad libitum drinking water

Biochem/physiol Actions

H1 histamine receptor antagonist.
Ketotifen fumarate plays a key role in preventing histamine release by blocking the histamine H1 receptors. It interferes with the release of histamine, serotonin and other inflammatory mediators from mast cells. It exhibits with anti-allergic activity, anti-inflammatory effects including mast cell stabilization. It has been widely used for ophthalmic allergic conjunctivitis.
