On May 29, 2026, the United States Food and Drug Administration (FDA) approved a new drug application for Cypsedo (cipepofol) for induction of general anesthesia in adults undergoing surgery. The Department of Health and Human Services provided the Drug Enforcement Administration (DEA) with a scheduling recommendation to place cipepofol, chemically known as 2-[(1R)-1-cyclopropylethyl]-6- isopropylphenol, in schedule IV of the Controlled Substances Act (CSA). In accordance with the CSA, as amended by the Improving Regulatory Transparency for New Medical Therapies Act, DEA is hereby issuing an interim final rule placing cipepofol in schedule IV of the CSA.

The Drug Enforcement Administration (DEA) issues this temporary order to schedule 1-(1-(1-(4-bromophenyl)ethyl)piperidin-4- yl)-5,6-dichloro-1,3-dihydro-2H-benzo[d]imidazol-2-one (commonly known as 5,6-dichloro brorphine or SR-14968); 5,6-dichloro-1-(1-(4- chlorobenzyl)piperidin-4-yl)-1,3-dihydro-2H-benzo[d]imidazol-2-one (commonly known as 5,6-dichloro desmethylchlorphine or SR-17018); 3-(3- (1-(1-(4-chlorophenyl)ethyl)piperidin-4-yl)-2-oxo-2,3-dihydro-1H- benzo[d]imidazol-1-yl)propanenitrile (commonly known as N-propionitrile chlorphine or cychlorphine); and 8-(1-(4-chlorophenyl)ethyl)-1-phenyl- 1,3,8-triazaspiro[4.5]decan-4-one (commonly known as spirochlorphine or R-6890), including their isomers, esters, ethers, salts, and salts of isomers, esters, and ethers, whenever the existence of such isomers, esters, ethers, and salts is possible, to schedule I under the Controlled Substances Act. DEA bases this action on a finding that placing 5,6-dichloro brorphine, 5,6-dichloro desmethylchlorphine, N- propionitrile chlorphine, and spirochlorphine in schedule I is necessary to avoid an imminent hazard to public safety. This order imposes the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule I controlled substances on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis, or possess) or propose to handle these substances.
