Spravato® (esketamine) has shown significant effectiveness in treating depression, particularly for patients who haven’t responded to traditional antidepressants. Clinical trials have demonstrated that when used alongside an oral antidepressant, Spravato® for depression treatment can produce rapid improvements in depressive symptoms, sometimes within hours or days rather than the weeks typically required by conventional therapies.
The medication is specifically FDA-approved for treatment-resistant depression and for depressive symptoms in adults with major depressive disorder who are experiencing acute suicidal thoughts or actions. Studies indicate that approximately 70% of patients with treatment-resistant depression show some response to Spravato, with many experiencing substantial relief from their symptoms.
However, the effectiveness of Spravato varies among individuals, and it’s not a universal solution for all depression cases. The ketamine-assisted treatment requires careful administration in a certified healthcare setting due to potential side effects, including dissociation, sedation, increased blood pressure, and risk of misuse. Patients must be monitored for at least two hours after each dose. The cost and accessibility can also be limiting factors, as treatment requires multiple clinic visits and may not be fully covered by all insurance plans.
What Makes Spravato® Different From Other Depression Medications?
Spravato® stands apart from other depression medications primarily through its unique mechanism of action and rapid onset of effects. Unlike traditional antidepressants such as SSRIs and SNRIs that work by modulating serotonin, norepinephrine, or dopamine levels and can take four to six weeks to show results, Spravato works on the glutamate system in the brain, specifically targeting NMDA receptors. This fundamentally different approach allows it to produce antidepressant effects much more quickly.
Esketamine is derived from ketamine, an anesthetic that has shown promise in depression treatment, but Spravato is formulated as a nasal spray specifically for psychiatric use. This novel mechanism makes it particularly valuable for treatment-resistant depression, offering hope to patients who haven’t found relief with two or more conventional antidepressant trials.
The difference between Spravato and ketamine from other depression treatments is the administration and monitoring requirements. While most antidepressants are taken at home as daily pills, Spravato must be administered in a certified healthcare facility under direct medical supervision. Patients self-administer the nasal spray at the clinic but then remain under observation for at least two hours due to potential side effects like dissociation, dizziness, and sedation.
How Quickly Does Spravato® Work for Depression Symptoms?
Spravato® is notable for its remarkably fast action compared to traditional antidepressants, offering hope to patients who need rapid symptom relief.
Initial Response Timeline:
- Some patients experience noticeable improvement in depressive symptoms within 24 hours of their first dose, though individual responses vary considerably.
- Clinical studies have shown that significant antidepressant effects can emerge within the first few days of treatment, far quicker than the 4-6 weeks typically required for SSRIs or SNRIs to take effect.
Treatment Phase Structure:
- The initial induction phase involves twice-weekly treatments for the first four weeks, during which many patients begin to see progressive improvement in their symptoms.
- After the induction phase, treatment frequency is reduced to once weekly for weeks 5-8, and then further reduced to maintenance dosing every week or every other week based on individual response.
Variability in Response:
- Not all patients respond at the same rate; while some experience rapid relief, others may require several weeks of treatment before noticing substantial benefits.
- The speed of response can depend on factors including the severity of depression, previous treatment history, and individual brain chemistry.
Sustained Effects:
- The rapid initial improvements must be maintained through continued treatment, as the effects are not permanent after a single dose.
- Regular maintenance sessions are necessary to sustain the antidepressant benefits, and discontinuing treatment may lead to symptom recurrence.

What Do Studies Show About Spravato® Effectiveness?
Clinical studies have provided substantial evidence supporting Spravato®’s effectiveness for treatment-resistant depression. In pivotal Phase 3 trials that led to FDA approval, researchers found that patients taking Spravato alongside an oral antidepressant showed significantly greater improvement in depression scores compared to those receiving only an oral antidepressant with a placebo nasal spray. One landmark study demonstrated that approximately 70% of patients with treatment-resistant depression experienced meaningful symptom improvement, with some achieving complete remission.
Long-term studies have also examined Spravato®’s sustained effectiveness and relapse prevention capabilities. A key maintenance study found that patients who responded well to Spravato® and continued maintenance treatment had significantly lower relapse rates than those who discontinued the medication, with relapse occurring in 27% of Spravato® patients versus 46% in the placebo group over 16 weeks.
However, researchers have noted that real-world effectiveness data continues to emerge, and not all patients respond equally well to treatment. Some studies indicate that while many patients experience initial benefits, maintaining those improvements requires ongoing treatment commitment.
Who Responds Best to Spravato® Treatment?
Research and clinical experience have identified certain patient characteristics and circumstances that tend to predict better outcomes with Spravato® treatment.
Patients With Treatment-Resistant Depression:
- Individuals who have failed to respond adequately to two or more traditional antidepressant trials are prime candidates, as Spravato® is specifically FDA-approved for this population.
- Those who have tried multiple classes of antidepressants (SSRIs, SNRIs, tricyclics, etc.) without sufficient relief often find Spravato® offers a new mechanism of action that can break through their resistance.
Patients With Severe or Acute Symptoms:
- People experiencing major depressive disorder with acute suicidal ideation or behavior may benefit from Spravato®’s rapid-acting properties, which can provide relief within hours or days.
- Individuals with severe depression who need faster symptom improvement than traditional antidepressants can provide tend to respond well to the medication’s quick onset.
Patients Who Can Commit to the Treatment Protocol:
- Those who have the time, transportation, and support to attend frequent clinic visits are more likely to complete treatment successfully.
- Patients with stable living situations and reliable schedules who can dedicate two to three hours per treatment session, including the mandatory monitoring period, show better adherence and outcomes.
Patients Without Certain Risk Factors:
- Individuals without a history of substance abuse or psychotic disorders generally respond better, as these conditions can complicate treatment or represent contraindications.
- Those without significant cardiovascular issues, particularly uncontrolled hypertension, are better candidates since Spravato® can temporarily elevate blood pressure.
Patients With Strong Support Systems:
- People who have family members or caregivers who can provide transportation after treatments and monitor for side effects tend to have better treatment experiences.
- Those engaged in comprehensive mental health care, including ongoing therapy and psychiatric management, typically achieve more sustained benefits from ketamine-assisted treatment in Southern California.
