How Ketamine Works vs. Antidepressants
When depression lingers despite multiple medications, patients often wonder if another path exists. Ketamine therapy has gained attention for working differently than traditional antidepressants.
Traditional Antidepressants: Slow but Steady
- Target serotonin or norepinephrine
- Onset: 4–6 weeks
- Effective for mild to moderate depression
- Limitations: delayed effect; not effective for all patients
Ketamine: A Different Pathway
- Targets glutamate, not serotonin
- Promotes new neural connections (neuroplasticity)
- Relief often within hours to days
- Delivery: IV infusion, nasal spray (esketamine), assisted psychotherapy
⚠️ Disclaimer: Not all patients respond to ketamine. Results vary.
Comparing the Two Approaches
| Aspect | Antidepressants | Ketamine |
|---|---|---|
| Target | Serotonin/norepinephrine | Glutamate |
| Onset | Weeks | Hours to days |
| Use case | Mild–moderate depression | Treatment-resistant depression, suicidal ideation |
| Delivery | Daily pills | Infusion, nasal spray, or therapy-assisted |
