Is Oveporexton legal in Australia?

A pill for narcolepsy type 1 that works on the brain's orexin wake system. It is not a peptide. The FDA approved it for adults on 5 August 2026. In two 12 week studies of 273 people, it kept people awake 14 to 20 minutes longer on a stay-awake test, while the dummy pill groups barely changed. Most people on it had trouble sleeping at night and needed to pee more often.

Oveporexton is a small molecule, not a peptide. 51 daltons.

How it works: In narcolepsy type 1, the brain cells that make orexin-A and orexin-B die off. So both orexin peptides run short, but the receptors they act on are still there.

Approval history: FDA approved 5 August 2026 (Orzeyful, NDA 220860) for narcolepsy type 1 in adults. It had orphan status, which is for drugs that treat rare diseases, and a priority (faster) FDA review. When the label was written, the DEA had not yet decided which controlled drug schedule it falls under.

Registers or lists medicines and health products on the ARTG, its official register. It also sorts substances into schedules in the Poisons Standard. Many peptides are Schedule 4 (prescription only). So having them without a prescription, or importing them for yourself, is restricted. That is true even when no product is registered.

The legal category above is how The Longevity Archive reads Therapeutic Goods Administration listings for Oveporexton on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.

Whether Oveporexton is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in Australia. Before you compete or get tested, look up Oveporexton by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
