Pharmacodynamics: The drug is an H1 receptor blocker as well as a moderate 5HT1 serotonin receptor blocker, thus attenuating the action of histamine and serotonin allergy mediators. A feature of the drug is that it makes an antihistamine effect not only by blocking H1 receptors, but also by reducing the content of histamine in tissues by accelerating its metabolism by the enzyme diamine oxidase, which breaks down endogenous histamine.
Sekhifenadine prevents or weakens the spasmogenic effect of histamine and serotonin on the smooth muscles of the bronchi, intestines, blood vessels, reduces capillary permeability, and has a pronounced antiallergic effect. Sekhifenadine affects the immunological reactivity of the body, reducing the number of antibody-forming and rosette-forming cells in the spleen, bone marrow, lymph nodes, and also reduces the increased concentration of class A and G immunoglobulins.
The drug poorly penetrates the blood-brain barrier, which explains the absence of a pronounced inhibitory effect on the central nervous system, however, in some cases, with individual hypersensitivity to the drug, a slight sedative effect may be noted. Sekhifenadine does not affect the biochemical parameters of blood and urine (including the concentration of glucose and cholesterol in the blood), the level of blood pressure, electrocardiogram indicators, does not increase the latent period of the conditioned reflex and does not affect the electroencephalogram indicators.
Application features: You should be careful in patients with impaired renal function (start treatment with a minimum dose), with severe diseases of the cardiovascular system, digestive tract, and liver. There are no data from clinical studies on the use of the drug in the elderly. The drug contains lactose, therefore, patients with rare hereditary forms of galactose intolerance, lactase deficiency or glucose-galactose malabsorption syndrome should not use the drug. During the period of treatment, one should refrain from drinking alcohol.
