Brexanolone is chemically known as 3[alpha]-hydroxy-5[alpha]-pregnan-20-one and is also referred to as allopregnanolone.

In accordance with the CSA, as revised by the Improving Regulatory Transparency for New Medical Therapies Act, DEA is hereby issuing an interim final rule placing brexanolone (including its salts, isomers, and salts of isomers whenever the existence of such salts, isomers, and salts of isomers is possible) in schedule IV of the CSA.
