This drug belongs to the group of psychotropic, narcotic substances, the distribution of which is controlled at the state level. One of the active ingredients is morphine, which acts on the higher parts of the brain and disrupts the natural transmission of pain impulses.

Papaverine, as you know, is an antispasmodic - this substance reduces the tone of smooth muscle fibers of blood vessels and internal organs. Codeine also belongs to the group of rather powerful narcotic analgesics.
