The pharmacodynamic effects of the administration of 2-adrenergic agonists both in a monovariant and in combination with drugs of other pharmacological groups are considered. Based on analysis of safety nonclinical studies the characteristics of main physiological effects of 2-adrenergic receptors as well as physiological effects of 2-agonists on various organs and systems are presented. For the determination of tendencies and directions in research of central 2-AM (dexmedetomidine) the analysis of bibliographical data, accumulated and extracted from Medline database with 5 year time-filter (VOSviewer, 1.6.11 version) has been carried out. For the further research of central 2-adrenomimetics and their application in clinical practice the following perspective directions have been determined: the study of effects and mechanisms of cytoprotectant and antioxidant action, the study of the use of drugs in a monovariant and in combinations for the development of analgesic drugs, anesthesia and development of combined formulations with a delayed release of antagonists designed to mitigate side effects.
