Research is being conducted on the use of remimazolam, sometimes in combination with other substances like esketamine, for procedures such as gastroscopy and surgery. The effectiveness and safety of remimazolam are being compared to other anesthetics, including propofol, in various patient populations, including the elderly and pediatric patients. The optimal dosing and potential benefits of remimazolam for painless procedures and minimizing side effects, such as postoperative nausea and vomiting, are being investigated.
