Abstract
Remimazolam is a novel ultrashort-acting benzodiazepine, which like midazolam, results in sedation, anxiolysis, and amnesia through its agonistic effects on the gamma-amino butyric acid A receptor. As opposed to midazolam, its unique metabolism is via tissue esterases, which results in a rapid elimination with a limited context sensitive half-life and prompt dissipation of its effect when administration is discontinued. Remimazolam received FDA approval for use in adults in 2020. In preliminary and initial clinical trials, its efficacy and safety has been suggested in the adult population, both as a primary agent for procedural sedation or as an adjunct to general anesthesia. There are limited data regarding the use of remimazolam in infants and children and its use in this population remains off label as it does not hold FDA-approval in pediatric-aged patients. This narrative outlines the pharmacologic properties of this unique medication, reviews previous published reports of its role in pediatric-aged patients, and discusses dosing parameters and clinical use in this population.
