About Remimazolam (CNS 7056)

Remimazolam is an innovative short-acting general anaesthetic/sedative. Sedatives are used, for example, in endoscopic procedures such as colonoscopies. After intravenous administration Remimazolam rapidly induces the desired sedation. Importantly, this sedative effect quickly disappears. This rapid offset of the effect of the substance is due to its metabolism by tissue esterase enzymes that are widely distributed throughout the body. Remimazolam is being developed as a sedative agent for day case procedures (procedural sedation) as well as for the induction and maintenance of anaesthesia. It could also be used as a sedative for patients in the Intensive Care Unit (ICU).

PAION is exploring partnering opportunities for the territories outside Japan, where the compound is partnered with Ono Pharmaceuticals in order to be able to initiate the development of Remimazolam in other indications as early as possible.

As recently published, the INN (International Nonproprietary Name) for CNS 7056 recommended by the World Health Organization is Remimazolam.
