If you've tried one antidepressant, then another, and maybe another, and you still feel stuck, this article is for you. Please don't give up.
Living with depression that hasn't responded to treatment can feel exhausting and discouraging. Many people start to believe that nothing will ever work for them. But over the past two decades, research has opened a genuinely different path, one that surprised even the scientists who discovered it.
Weeks... or Hours? The Discovery That Changed the Field
For decades, antidepressants usually took 4 to 6 weeks to start working, and roughly a third of people didn't get enough relief even after trying several.
Then researchers found something unexpected. In early studies, a single low dose of ketamine, a medication long used for anesthesia, eased depression symptoms within hours to a day, including in people who hadn't responded to other treatments. Few in the field expected an antidepressant to work that quickly. It changed how scientists think about depression and how the brain heals.
From Research to FDA Approval: Spravato®
That research led to Spravato® (esketamine), a nasal spray made from one form of the ketamine molecule.
- The FDA gave esketamine Breakthrough Therapy designation, a status reserved for treatments that early evidence suggests may offer substantial improvement over existing options.
- 2019: Spravato was approved for treatment-resistant depression.
- 2020: It was approved for adults with major depression who have suicidal thoughts or actions.
- 2025: It was approved for use as a stand-alone treatment, not only alongside an oral antidepressant.
Spravato was the first antidepressant with a truly new mechanism of action in decades.
Your Brain Doesn't Just Record the World. It Interprets It.
To understand why Spravato is so different, it helps to understand how the brain makes sense of everyday life.
Every moment, your brain takes in a flood of sensory information: what you see and hear, what people say, the expression on someone's face, the sensations in your body. Your brain doesn't experience all of this "raw." Instead, it filters everything through your beliefs, memories, and expectations about yourself and the world, and fits each new experience into what it already "knows."
Most of the time, this filter is helpful. It lets you make sense of life quickly without starting from scratch every time.
What Depression Does: The Filter Turns Rigid
In depression, that filter can become stuck. Thoughts like these start to act as the lens for everything:
- "I'm a failure."
- "Nothing is ever going to change."
- "It's my fault."
- "Why even try?"
Now every experience gets absorbed into the same painful story. A compliment feels fake. A small mistake feels like proof. A quiet afternoon feels like loneliness. The brain keeps assimilating new information into old, rigid patterns instead of updating them.
Think of a sled track worn deep into snow. After enough runs, the sled slides into the same groove every time, even when you want to go somewhere else. That's what rumination can feel like.
How Spravato Helps Loosen the Groove
Most traditional antidepressants work on serotonin, norepinephrine, or dopamine. Spravato works differently, on the brain's glutamate system, the main signaling system for learning and forming new connections.
- It acts on NMDA receptors. Esketamine blocks NMDA receptors, which triggers a burst of glutamate activity in key brain regions.
- It supports neuroplasticity. That activity releases growth signals such as BDNF (brain-derived neurotrophic factor), which help brain cells form new synaptic connections. In research, these changes can appear within about a day.
- It may quiet the "default mode network." This brain circuit is closely tied to self-focused thinking, rumination, and self-criticism. Studies suggest ketamine-based treatments may temporarily loosen its grip.
Scientists are still studying exactly how these effects fit together, but the big picture is encouraging: rather than only adjusting brain chemistry, Spravato appears to help the brain become more flexible.
A Window of Flexibility: Fresh Snow, New Paths
Going back to our snow analogy, Spravato is a bit like a fresh snowfall. The old grooves soften, and new paths become possible.
Many people describe being able to step back from their thoughts and see themselves with more perspective and less judgment. Instead of "This always happens to me," there's room for "Maybe this isn't the whole story." That shift in perspective, being able to see ourselves differently, is often where real healing begins.
Why Therapy Matters: Medicine Opens the Door, You Walk Through It
That flexible window is a powerful time to practice new ways of thinking and build healthier patterns. That's why, at NextGen Psyche and Wellness, our Spravato (NMDA-Receptor Therapy) sessions include psychotherapy or VR therapy during the final phase of the visit. We want to help you use that window to create lasting change, not just short-term relief.
What Treatment Looks Like
- Spravato is a nasal spray that you give yourself in a certified clinic, under the supervision of a healthcare provider.
- You're monitored for at least 2 hours after each dose.
- Common side effects include feeling detached or "floaty" (dissociation), dizziness, nausea, sleepiness, and a temporary increase in blood pressure. These usually ease within the monitoring period.
- You'll need a ride home and shouldn't drive until the next day after a restful night's sleep.
- Treatment typically starts with twice-weekly sessions, then tapers to weekly or every-other-week visits.
Spravato isn't right for everyone. Your provider will review your medical history, blood pressure, and other medications to decide whether it's a safe option for you.
If You've Tried Before and It Didn't Work, That's Not the End
Treatment-resistant depression is usually defined as depression that hasn't improved after trying two or more antidepressants. If that sounds like you, it doesn't mean you're broken or beyond help. It may simply mean your brain needs a different approach.
