[The problems of the experimental and clinical pharmacology of vein-tonicizing agents].

General regularities of changes in the regional venous and systemic hemodynamics under the influence of venotropic drugs are considered. Particular emphasis is given to problems of pharmacodynamics of venotropic agents. The mechanisms of their action, similarity and differences in phlebohemodynamic effects, problems of clinical use and also prospects of the further research on pharmacology of venotropic agents are discussed.
