In the world of ketamine therapy, there is a distinct divide: the FDA-approved, insurance-covered “Gold Standard” (Esketamine/Spravato) versus the cheap, off-label generic (Racemic Ketamine). In this episode, we step into the ring to judge “The Nasal Spray Wars” using a groundbreaking 2026 meta-analysis by Bahji and colleagues published in the Journal of Affective Disorders.

We break down the “skim milk vs. whole milk” pharmacology: Esketamine isolates just the S-isomer, while generic ketamine contains both the S and R isomers. Big Pharma argues the isolate is cleaner, but the data tells a different story. We reveal the study’s stunning conclusion: there is no significant difference in symptom relief between the two. In fact, the “cheap” generic showed higher remission rates and lower dropout rates than its expensive counterpart.

The discussion tackles the massive elephant in the room: accessibility. With Spravato costing thousands of dollars per month and requiring strict in-clinic monitoring, we ask if the “premium” price tag is buying better health or just a patent. We conclude with a verdict for patients paying out-of-pocket: choosing the generic isn’t “settling”—it may actually be the more effective, and certainly the more sustainable, path to recovery.
