About Remimazolam

 

 

Remimazolam is an ultra-short-acting intravenous benzodiazepine sedative/anesthetic. In the human body, remimazolam is rapidly metabolized to an inactive metabolite by tissue esterases and is not metabolized by cytochrome-dependent hepatic pathways. Like other benzodiazepines, remimazolam can be reversed with flumazenil to rapidly terminate sedation or anesthesia if necessary. In clinical studies, remimazolam demonstrated efficacy and safety in around 2,500 volunteers and patients. Data so far indicate that remimazolam has a rapid onset and offset of action combined with a favorable cardio-respiratory safety profile.

 

In Japan, licensee Mundipharma received market approval in general anesthesia in January 2020. In the U.S., licensee Cosmo Pharmaceuticals submitted a New Drug Application for procedural sedation in April 2019, with a PDUFA decision date of 05 July 2020. In China, licensee Yichang Humanwell filed for market approval in procedural sedation in November 2018. In South Korea, licensee Hana Pharm filed for market approval in general anesthesia in December 2019. In Europe, PAION submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) in procedural sedation in November 2019 and results of an EU Phase III trial in general anesthesia are expected in the second half of 2020.

 

In addition to procedural sedation and general anesthesia, based on positive Phase II study results, ICU sedation is another possible indication for remimazolam.
