Pharmacodynamics

The therapeutic effect of Tavegil is based on its active substance - 1-methyl-2-[2-(α-methyl-para-chlorobenzhydryloxy)-ethyl]-pyrrolidine in the form of fumarate, which affects the release of the endogenous neurotransmitter of immediate-type allergic reactions - histamine.

This occurs due to blocking the stimulation of peripheral H1 histamine receptors located on the outer surface of the cytoplasmic membrane of cells. As a result, histamine synthesis does not increase, capillary permeability decreases, and - as a consequence - allergic reactions of the body in the form of hyperemia and itching of the skin, irritation and swelling of the mucous membranes, bronchial spasms, etc. are suppressed.
