Ketotifen Pharmacodynamics
Ketotifen belongs to the group of cycloheptathiophenones and has a pronounced antihistamine effect. It does not belong to the bronchodilator antiasthmatic agents
The mechanism of action is associated with inhibition of release of histamine and other mediators from mast cells, blockade of histamine H1-receptors and inhibition of phosphodiesterase enzyme, as a result of which the level of cAMP (cyclic adenosine monophosphate) in mast cells increases. Suppresses the effects of PAF (platelet-activating factor). Does not stop asthmatic attacks, but prevents their occurrence and leads to a reduction in their duration and intensity, and in some cases they disappear completely. Facilitates expectoration of sputum.

Atopic bronchial asthma (as part of complex therapy), allergic rhinitis, conjunctivitis.
