If you’ve struggled with depression, you might have already experienced how slow traditional medications can be. Most antidepressants take weeks—sometimes months—to deliver any noticeable change. And even then, the effects aren’t guaranteed. For people with treatment-resistant depression, that wait can feel endless.
But what if you didn’t have to wait? Esketamine, an FDA-approved therapy, is helping some patients feel relief within hours or days, not weeks. At PMC Heal, we believe in offering science-backed innovation alongside compassionate care. Let’s explore how esketamine compares with conventional medications, why it works differently, and how it might fit into your treatment plan.
How Traditional Antidepressants Work—and Why They’re Slow
The most commonly prescribed antidepressants fall into two categories: SSRIs (Selective Serotonin Reuptake Inhibitors) and SNRIs (Serotonin and Norepinephrine Reuptake Inhibitors). These drugs increase the availability of certain neurotransmitters in the brain—namely serotonin and norepinephrine—to help improve mood and emotional balance.
But here’s the catch: These medications don’t work immediately. It usually takes 4 to 6 weeks to feel their full effects. Even then, many patients need to try multiple medications and dosages before finding the right fit. This trial-and-error process can be frustrating, emotionally draining, and time-consuming.
While traditional antidepressants have helped millions, they don’t work for everyone. That’s where esketamine comes in.
Introducing Esketamine: What It Is and How It Works
Esketamine is a derivative of ketamine, a medication that’s long been used as an anesthetic. In recent years, scientists discovered that at lower, controlled doses, ketamine and its derivatives could provide rapid relief from depressive symptoms, especially in people who haven’t responded to traditional treatments.
The esketamine drug class is known as NMDA receptor antagonists. These drugs target the brain’s glutamate system, which plays a key role in learning, memory, and emotional processing. By enhancing neuroplasticity and repairing damaged synaptic connections, esketamine helps the brain “rewire” itself more effectively and quickly than serotonin-based medications.
You may recognize esketamine’s brand name, Spravato. It’s administered as a nasal spray and must be used in a clinical setting under medical supervision.
FDA Approval and What It Means for Patients
The esketamine FDA approval came in 2019, specifically for adults with treatment-resistant depression. That means patients who haven’t responded to at least two other antidepressants may be eligible.
FDA approval isn’t just a regulatory stamp; it carries weight for patients. It means that esketamine has undergone rigorous testing for safety and efficacy. It also means that insurance providers are more likely to cover it, and patients can receive treatment in licensed, controlled environments.
Spravato must be administered in a certified clinic like PMC Heal, where patients are monitored during and after each session for potential side effects.
Esketamine vs. Oral Antidepressants: A Head-to-Head Comparison
So how does esketamine stack up against traditional options? Here’s a quick look at the key differences:
| Factor | Esketamine (Spravato) | Traditional Antidepressants |
| Onset Time | Hours to days | 4–6 weeks on average |
| Administration | Nasal spray (in-clinic only) | Oral pills taken daily |
| Target Pathways | Glutamate/NMDA receptors | Serotonin and/or norepinephrine |
| Ideal Use Case | Treatment-resistant depression | General depression (first-line treatment) |
| Monitoring | Required after each dose | None |
This difference in speed alone can be life-changing for people who need fast relief, especially those experiencing suicidal thoughts or deep functional impairment.
How Esketamine Fits Into Broader Treatment Plans
Esketamine isn’t a replacement for all other depression treatments. In fact, it’s often prescribed alongside a traditional oral antidepressant to increase its effectiveness. Many patients also continue with psychotherapy, lifestyle changes, and regular follow-ups as part of a holistic care plan.
At PMC Heal, we believe that mental health treatment should never be one-size-fits-all. Our clinicians conduct comprehensive evaluations to determine whether Spravato is a good fit and how to integrate it into a broader, personalized strategy for healing.
Whether you’re just starting to explore esketamine or ready to take the next step, we’ll work with you every step of the way.
Changing the Timeline for Treatment
Depression is already hard. Waiting weeks for a treatment that might work can make it even harder. Esketamine offers a faster-acting, science-backed alternative that’s changing how we think about timelines in mental health care.
If you’ve tried other medications without success, it might be time to explore whether Spravato is right for you. As one of the clinics certified to administer this treatment, PMC Heal is here to help you navigate your options with compassion, clarity, and clinical expertise.
