Phencarol 25mg 20 tablets — Made in Latvia — Free Delivery

Pharmacodynamics. The active substance of the preparation Phencarol is a derivative of quinuclidylcarbinol, which reduces the effect of histamine on organs and systems. Chifenadine is a competitive H1 receptor blocker. in addition, it activates the enzyme diamine oxidase, which breaks down about 30% of endogenous histamine. this explains the effectiveness of hifenadine in patients who are insensitive to other antihistamines. hifenadine poorly penetrates the geb and has little effect on the processes of deamination of serotonin in the brain, has little effect on the activity of mao. the antihistaminic properties of hifenadine are associated with the presence of a cyclic quinuclidine nucleus in the structure and the distance between the diphenylcarbinol group and the nitrogen atom. in terms of antihistamine activity and duration of action, hifenadine is superior to diphenhydramine. reduces the toxic effect of histamine, in particular, eliminates or weakens its bronchoconstrictor effect and spasmodic effect on intestinal smooth muscles, has a moderate anti-serotonin and weak anticholinergic effect, pronounced antipruritic and desensitizing properties. Khifenadine reduces the severity of the hypotensive effect of histamine and its effect on capillary permeability, does not directly affect cardiac activity and blood pressure, does not have a protective effect in aconite arrhythmias.

Hifenadine does not have a depressing effect on the central nervous system, but with individual hypersensitivity, a weak sedative effect is possible. The preparation has low lipophilicity, so its content in the brain tissues is low (0.05%), which explains the lack of a depressing effect on the central nervous system.
