Pharmacological action

Ketotifen has a pronounced antihistamine, weakly antiserotonin effect, without an anticholinergic effect. In higher doses, it has a slightly depressing effect on the central nervous system.

Pharmacodynamics

The mechanism of action of Ketotifen is associated with the ability to inhibit the release of histamine and other inflammatory mediators from mast cells due to membrane stabilization, as well as due to the blockade of histamine H1 receptors. Ketotifen inhibits the enzyme phosphodiesterase, which increases the level of cyclic adenosine monophosphate in mast cells.

The drug reduces or suppresses skin and bronchial reactions caused by the antigen, which causes its use for preventive purposes. When used as monotherapy, it does not stop asthma attacks, but leads to a decrease in the number, duration and intensity of these attacks, and in some cases they completely disappear. Reduces eosinophilia, reduces the need and frequency of use of anti-asthmatic drugs: corticosteroids, bronchodilators, etc.

The drug is characterized by good and fast resorption, without the risk of accumulation in the body. Bioavailability is approximately 50%, which is associated with metabolism during the” first pass ” through the liver.

The time to reach the maximum plasma concentration is 2-4 hours, and the binding to plasma proteins is 75%. Elimination from the body proceeds in two phases, and within 48 hours the main part of the single dose taken is excreted in the urine. The therapeutic effect develops after 2 weeks of a course of taking the drug.
