Ketotifen fumarate, also known as methylpheni date, thioperidone, sardiophenone, thiazoxide and ketotifol, is a potent anti-allergic drug with both a tricyclic and piperidine structure, characterized by strong antagonism of histamine H1 receptors and inhibition of the release of allergic response mediators. It inhibits the release of a variety of mediators from mast cells, basophils and macrophages, including slow-reacting substances and other reactive substances, has an antagonistic effect on calcium ions, inhibits phosphodiesterase and increases the cAMP content in mast cells. It inhibits chemotaxis and inflammatory response of neutrophils, which is 10 times stronger than paracetamol and has a long-lasting effect, stronger than sodium cromoglycate. Ketotifen fumarate has a therapeutic effect on both type I and type III metabolic reactions.
