of Phencarol – antiexudative, antipruritic, antiallergic, decongestant.

Pharmacodynamics

The Active ingredient of the drug hifenadine-a blocker of H1-histamine receptors-prevents the development and facilitates the course of allergic reactions. It has an anti-allergic, anti-exudative and antipruritic effect, preventing the development of allergic inflammation in the tissue. Weakens the effect of histamine, reduces its effect on vascular permeability (reducing permeability, has an anti-edematous effect), reduces its bronchospastic effect and spasmogenic effect on intestinal smooth muscle, weakens the hypotensive effect of histamine. Hifenadine reduces the content of histamine in tissues (due to the ability to activate diamine oxidase, an enzyme that inactivates histamine). During the course of treatment, the antihistamine effect of hifenadine is not reduced. It has a moderate antiserotonin effect, shows weak m-holinoblokiruyuschuyu activity.

Pharmacokinetics

45% of hifenadine is rapidly absorbed from the gastrointestinal tract and is detected in body tissues within 30 minutes. Cmax of Active ingredient in blood plasma is reached after 1 h. It has low lipophilicity, poorly penetrates the BBB. The highest content of the Active ingredient was observed in the liver, slightly lower in the lungs and kidneys, and the lowest in the brain (less than 0.05%, which explains the absence of a depressing effect on the central nervous system). Hifenadine is metabolized in the liver. Metabolites are excreted by the kidneys and intestines. The unabsorbed part of the drug is removed from the intestine.
