FDA eyes global bans on Spirochlorphine and weird drug cousins
Published Date: 8/26/2026
Notice
Summary
The FDA is asking the public to share their thoughts on eight drugs that might get new international rules to control their use and abuse. This affects doctors, patients, and drug makers because it could change how these drugs are used medically or restricted worldwide. Comments are open until September 3, 2026, so jump in and have your say before the deadline!
Analyzed Economic Effects
5 provisions identified: 2 benefits, 3 costs, 0 mixed.
International Controls Could Limit Trade
The notice says that if the Expert Committee recommends international controls, such controls could limit the manufacture and distribution (including import/export) of the listed substances and could impose certain recordkeeping requirements. The FDA is seeking public comment through September 3, 2026.
Etomidate Pre-Review Could Affect Access
Etomidate is approved in the United States for induction of general or supplemental anesthesia, but the ECDD will perform a pre-review to decide whether a full critical review is justified. Other countries adopted controls (e.g., UK: July 2025; South Korea: February 2025; Taiwan: November 2024; Hong Kong: February 2025).
Medetomidine Review and Veterinary Risks
Medetomidine is approved for veterinary use only and has been increasingly detected as an adulterant in illicit drug supplies; Pennsylvania classified it as Schedule III in 2026. The ECDD will pre-review medetomidine to assess whether to advance to a full critical review.
Federal Temporary Schedule I Actions Announced
The notice states that etomethazene is temporarily controlled in Schedule I under the Controlled Substances Act as of October 15, 2025, and that the DEA published a notice of intent on July 1, 2026 to temporarily control cychlorphine and spirochlorphine in Schedule I. Cychlorphine has been confirmed in 225 law enforcement seizures and associated with at least 55 fatalities in the United States as of early 2026.
Benzodiazepines Under Critical Review
The ECDD will conduct critical reviews of three designer benzodiazepines — clobromazolam (phenazolam), desalkylgidazepam (bromonordiazepam), and ethylbromazolam — which are not currently controlled under the CSA and have no approved U.S. medical uses. Desalkylgidazepam has been detected in 227 polydrug intoxication and fatality cases; ethylbromazolam was detected in 13 toxicology cases and 93 drug material cases by October 2025.

These therapeutic equivalence evaluations have been prepared to serve as public information and advice to state health agencies, prescribers, and pharmacists to promote public education in the area of drug product selection and to foster containment of health care costs.
