The medicine is a lozenge that dissolves in your mouth. There’s no IV and no injection. The effects come on more gradually, which leaves room to settle in and work together as the experience unfolds.
Is a lozenge as effective? Lozenges are dosed for how they absorb, and studies of sublingual ketamine show meaningful benefit. See the research
Is a lozenge as effective? Lozenges absorb differently than an injection, so they’re dosed differently. In a study of more than 1,200 people using sublingual ketamine, about 63% reported their depression improved by half or more. Head-to-head trials against injections haven’t been done, so no one can honestly say one route is better. What the research does show is that lozenges can work well, and in ketamine-assisted therapy the gentler onset leaves more room for the therapy itself.
