The American Journal of Psychiatry Looks at Six Years of FDA-Approved Spravato
Esketamine, a nasal spray derived from ketamine, was approved by the FDA in 2019 for treatment-resistant depression. This approval followed years of research suggesting ketamine’s potential to offer rapid relief for severe depression symptoms. However, six years after its introduction, many clinical challenges remain unresolved. The increased use of esketamine in mental health treatment has been accompanied by concerns about its efficacy, side effects, and potential abuse risks. The American Journal of Psychiatry took a deep dive into what the last six years of FDA-approved nasal ketamine has looked like.

Key Takeaways
| Takeaway | Description |
|---|---|
| Short-term Efficacy | Esketamine has shown rapid efficacy, with patients often reporting symptom relief within the first 24 to 48 hours of administration. However, while initial improvements are promising, the long-term benefits remain uncertain, with some studies indicating diminishing effects over time. |
| Limited Suicidality Impact | Esketamine has demonstrated potential in reducing severe depressive symptoms but has not shown a strong impact on suicidality in most clinical trials. This is a key area of concern, as rapid relief is critical for individuals at imminent risk. |
| Clinical Limitations | Esketamine’s trials have often faced challenges such as small effect sizes and significant placebo responses. The robustness of the findings has been questioned, particularly as clinical use grows beyond controlled environments. Nevertheless, it offers hope for treatment-resistant depression, where conventional antidepressants fail. |
| Abuse Potential | Despite its therapeutic applications, esketamine remains a Schedule III controlled substance due to concerns about its potential for abuse and misuse. The drug’s dissociative effects raise red flags, though its in-clinic administration mitigates these risks. Continued monitoring and regulatory oversight are essential to address these concerns. |
| Regulatory Concerns | Esketamine was approved by the FDA based on data from a single pivotal trial, leading to concerns about the completeness and quality of the evidence supporting its approval. However, its introduction into clinical practice has provided an alternative for patients who do not respond to traditional therapies. |
| Rapid Onset of Action | One of the most notable positive aspects of esketamine is its rapid onset. For individuals who have struggled with severe depression for years without relief, esketamine offers a potentially life-changing quick response, which is not commonly seen in other antidepressants. |
| Promising in Treatment-Resistant Depression | Esketamine has shown substantial promise in treating patients with treatment-resistant depression, providing an option for those who have not found relief through conventional antidepressants or psychotherapy. Its potential to break through therapeutic barriers makes it a valuable tool in psychiatric care. |
| Positive Patient Experience | Many patients who have used esketamine report positive experiences, particularly when conventional treatments have failed. Improved mood, increased energy, and a sense of clarity have been commonly noted, offering a glimmer of hope for those previously stuck in the cycle of depression. |
| Challenges in Long-Term Use | While esketamine offers rapid symptom relief, challenges persist with maintaining the benefits over time. The risk of relapse after discontinuation of treatment or prolonged use remains an open question, with some patients experiencing a return of depressive symptoms within weeks of finishing treatment. |
| Regulated Use and Monitoring | To ensure safety, esketamine is administered under medical supervision, with patients monitored for at least two hours post-administration. This regulated approach has been successful in minimizing adverse effects and controlling misuse, though access remains limited due to these strict guidelines. |

Clinical Conundrums and Unanswered Questions
Since its approval, esketamine has sparked a shift in psychiatric care, particularly for patients resistant to traditional antidepressants. However, the drug’s clinical use is not without complexities. The nasal spray has been associated with dissociative effects, sedation, and, notably, its potential for abuse. This has led to the implementation of strict monitoring protocols, including in-clinic administration and a two-hour post-dose observation period. With increasing numbers of clinics offering esketamine and its popularity growing, the risks tied to unsupervised use, especially in online platforms, have become a significant concern.
Moreover, while initial studies of esketamine suggested rapid relief from depression, newer data raises questions about its long-term effectiveness. Most trials show that the benefits of the drug may not extend beyond a few weeks, prompting experts to question its long-term viability as a treatment option.
Looking Ahead: A Complex Future
The future of esketamine in clinical practice hinges on ongoing research. Although some patients show meaningful improvements after multiple doses, the drug’s ultimate role remains unclear. More studies are needed to determine whether continuation treatment beyond the initial phase offers lasting benefits. Additionally, the risks associated with its use in unsupervised settings must be addressed, especially in light of the growing number of at-home ketamine treatment options.
As the landscape of mental health treatment continues to evolve, esketamine’s place in therapy will be shaped by both new evidence and regulatory oversight. For clinicians and patients alike, the challenge will be balancing its potential benefits with the risks and limitations that still linger.
