Ketotifen is a second-generation noncompetitive H1-antihistamine and mast cell stabilizer.

Ketotifen also has pronounced antihistaminic and anti-anaphylactic properties resulting in moderate to marked symptom improvement in most animal models with atopic dermatitis, seasonal or perennial rhinitis, allergic conjunctivitis, chronic or acute urticaria, or food allergy.


Molecular Formula: C19H19NOS

Molecular weight: 309.4 g/mol

CAS number: 34580-13-7

IUPAC name: 2-(1-methylpiperidin-4-ylidene)-6-thiatricyclo[,7]tetradeca-1(14),3(7),4,10,12-pentaen-8-one


Ketotifen is a non-competitive histamine antagonist and mast cell stabilizer. During research with rats, ketotifen acted as a non-bronchodilator antiasthmatic drug by inhibiting the effects of endogenous substances known to be inflammatory mediators after oral administration. 

Even though effects can take 6 to 12 weeks to become noticed, using ketotifen has been demonstrated to reduce the frequency, severity, and duration of asthma symptoms and may reduce the use of other asthma therapies.
