摘要：
Dexmedetomidine has been shown to provide a prolonged anxiolytic effect by inhibiting adrenergic neurons in the locus coeruleus, as demonstrated in a mouse model. This study reveals that a single low dose of Dex can alleviate anxiety symptoms for at least three days, highlighting its potential as a long-acting therapeutic option for anxiety disorders. The research elucidates the underlying neural mechanisms, emphasizing the role of α2 adrenergic receptors in mediating these effects, which could lead to innovative treatment strategies for anxiety-related conditions.
