Schedules of Controlled Substances: Placement of Oliceridine in Schedule II

This final rule adopts, with a change as mentioned below, an interim final rule with request for comments published in the Federal Register on October 30, 2020, placing oliceridine, N-[(3- methoxythiophen-2-yl)methyl]({2-[(9R)-9-(pyridin-2-yl)-6- oxaspiro[4.5]decan-9-yl]ethyl{time} )amine fumarate, including its isomers, esters, ethers, salts and salts of isomers, esters and ethers whenever the existence of such isomers, esters, ethers and salts is possible, in schedule II of the Controlled Substances Act. In response to an error in the chemical name of oliceridine as noted by one of the commenters to the interim final rule, the Drug Enforcement Administration makes a correction to the above mentioned chemical name of oliceridine by removing the word "fumarate" to read as N-[(3- methoxythiophen-2-yl)methyl]({2-[(9R)-9-(pyridin-2-yl)-6- oxaspiro[4.5]decan-9-yl]ethyl{time} amine. This change clarifies the control of oliceridine free base and its salts, to include the fumarate salt, by definition.
