Remimazolam: First Approval.

Remimazolam (Anerem® in Japan; ByFavo™ in the USA; Aptimyda™ in the EU) is an ultra-short-acting intravenous (IV) benzodiazepine sedative/anesthetic being developed by PAION AG in conjunction with a number of commercial partners for use in anesthesia and procedural sedation. Remimazolam was approved on 23 January 2020 in Japan for use in general anesthesia in adult patients. Remimazolam is also undergoing regulatory assessment in South Korea for this indication and for use in procedural sedation in the USA, the EU and China. This article summarises the major milestones in the development of remimazolam for this first approval for the induction and maintenance of general anaesthesia, and its potential upcoming approvals in general anaesthesia and procedural sedation.
