“…α2-AM in analgesic doses is known to cause muscle relaxation [37]. This effect is associated with inhibition of α2-AR at the level of the spinal cord interneurons [12]. It should be noted that tizanidine is effective in reducing muscle spasticity in stroke, traumatic brain injury and multiple sclerosis due to the pronounced muscle relaxant effect [9].…”

“…It was shown that stimulation of central α1-receptors reduces the hypnotic effect of α2-AM, for example, dexmedetomidine [11]. It was shown that with the introduction of α2-AM in high and toxic doses at the initial period of drug action, the effects of α1-AR activation prevail [12].…”
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
