Zatin (Ketotifen) is an antiasthmatic drug with marked antianaphylactic properties and a specific antihistaminic

effect. Its antiasthmatic activity is attributed to a number of factors including inhibition of phosphodiesterases,

inhibition of PAF induced accumulation of eosinophils in the airways, inhibition of the release of histamine and

leukotrienes and functional antagonism of the effects of leukotrienes. Ketotifen is almost completely absorbed

after oral administration.Bioavailability is approximately 50% due to a first pass effect in the liver. Peak plasma

concentration is achieved within 2 - 4 hours. Protein binding is 75%. Ketotifen is eliminated biphasically with a

short half life of 3 - 5 hours and a longer one of 21 hours . 70% is excreted in urine as metabolites.


Zatin is indicated in :

- Long term prevention of bronchial asthma, allergic bronchitis and asthmatic symptoms associated with hay fever.
