Ketamine brand and generic name?

What’s the generic name for ketamine?
The drug itself is called ketamine. It is a dissociative anesthetic and, more recently, a rapid‑acting antidepressant when given in low doses. The term “ketamine” refers to the compound’s chemical structure and is the generic name used in all clinical and regulatory documents. [1]

Which brands market ketamine?
The most widely known brand is Ketalar, sold by Parke‑Dyson (now Pfizer). Ketalar is an injectable solution used for anesthesia and as part of pain‑management protocols. [2]
Other U.S. brands include KetaTract (Syntheon) and Eskul (Syntheon), both marketed as injectable ketamine for similar indications. [3]

Are there brand names for ketamine used outside the U.S.?
In Canada, the product Ketamine® (generic name sold under the brand “Ketamine”) is distributed by the company Syntheon. In Australia and New Zealand, ketamine is available under the brand Ketamine and sometimes under “Eskul.” These are essentially the same formulation, differing only in labeling and packaging. [4]

What about esketamine, the “ketamine derivative” used for depression?
Esketamine is the S‑enantiomer of ketamine. Its FDA‑approved brand name is Spravato. Spravato is a nasal spray indicated for treatment‑resistant depression. Although it is chemically related to ketamine, it is marketed under a distinct brand and has its own regulatory approvals. [5]

Do generic ketamine products exist?
Yes. Once the patents for the original ketamine formulations expired, generic manufacturers began offering ketamine injectable solutions. These generics carry the generic name “ketamine” and are available in the United States, Canada, and other markets under various generic labels, often without a distinct brand name. [6]
