Abstract: Remimazolam is a new ultra-short-acting sedative, with rapid onset and recovery, metabolism independent of liver and kidney function, light respiratory inhibition, stable hemodynamics, long time application without accumulation. Carboxylic acid metabolites have no pharmacological effects, and can be rapidly reversed by antagonist flumazenil, which is expected to become a new choice of clinical sedative. In this paper, pharmacological characteristics and recent research progress of remimazolam are reviewed, which can provide reference for clinical safe drug use.

Key words: remimazolam, calm, general anesthesia
