MEDIOCON INC – Ketotifen is a synthetic antihistamine and mast-cell stabilizing pharmaceutical active ingredient belonging to the tricyclic compound class. It is primarily used in pharmaceutical formulations for the management of allergic conditions and is commonly supplied commercially in salt forms such as Ketotifen Fumarate. PubChem identifies Ketotifen with CAS 34580-13-7, molecular formula C₁₉H₁₉NOS, and molecular weight approximately 309.4 g/mol.
Ketotifen is an H1-histamine receptor antagonist with mast-cell stabilizing properties. It has been used in pharmaceutical preparations for allergic disorders and is particularly well known in ophthalmic formulations for temporary relief of itchy eyes associated with allergies. Current U.S. labeling identifies ketotifen fumarate as the active ingredient in ophthalmic products.
