Neuroprotection and mechanisms of dexmedetomidine / 中国药理学通报

ABSTRACT

Dexmedetomidine( DEX) is a pure potent, highly se-lective and highly specific agonist ofα2-adrenergic receptors with sedative, analgesic and sympatholytic properties. The sedative effect mimics natural sleep of“arousable” and“cooperative” se-dation without respiratory depression. Due to the above properties and advantages, DEX has received adequate attention in clinical practice and its spectrum of application is also expanding. In re-cent years, it is proved that DEX is neuroprotective not only in animal researches but also in clinical studies. The neuroprotec-tion of DEX and its related mechanism will be briefly reviewed in this paper.
