FDA Approves First Standalone Nasal Spray for Treatment-resistant Depression
In a groundbreaking move, teh Food and Drug Administration (FDA) has approved SPRAVATO®, a nasal spray containing esketamine, as the first-ever standalone treatment for treatment-resistant major depressive disorder (MDD). This marks a significant milestone for the estimated 21 million adults in the U.S. affected by MDD, a third of whom experience the treatment-resistant form of the condition.
Treatment-resistant depression occurs when symptoms persist despite standard treatments, such as at least two antidepressants and psychotherapy. While options like transcranial magnetic stimulation exist, the approval of SPRAVATO® offers a new, option approach for those who haven’t found relief through conventional methods.
Esketamine, the active ingredient in SPRAVATO®, is the mirror-image (enantiomer) of the anesthetic drug ketamine. Initially approved in 2019 for use alongside oral antidepressants, its standalone approval comes after fresh clinical trial data showed its efficacy. At week 4 of the study, 22.5% of patients taking SPRAVATO® achieved remission from thier treatment-resistant MDD, compared to just 7.6% of the placebo group.
The exact mechanism of esketamine remains unclear, but it is known to increase levels of glutamate, an excitatory neurotransmitter. Despite its potential for abuse, the nasal spray will only be available through a restricted program and must be administered in a healthcare setting. Patients are monitored for at least two hours post-administration to manage potential side effects, which can range from nausea and headaches to dissociation and hallucinations.Dr. Bill Martin, Global Therapeutic Area Head, Neuroscience at Johnson & Johnson Innovative Medicine, emphasized the meaning of this approval. “Treatment-resistant depression can be very complicated, especially for patients who do not respond to oral antidepressants or cannot tolerate them. For too long, healthcare providers have had few options to offer patients much-needed symptom betterment,” he saeid in a statement.
With SPRAVATO®, patients may experience improvements in depressive symptoms as early as 24 hours and at 28 days, without the need for daily oral antidepressants.

In a landmark decision, the U.S. Food and Drug Administration (FDA) has approved SPRAVATO®, a nasal spray containing esketamine, as the first standalone treatment for treatment-resistant major depressive disorder (MDD). This innovation offers new hope for millions struggling with this challenging condition. To delve deeper into this advancement, we spoke with Dr. Emily Carter, a renowned psychiatrist and expert in treatment-resistant depression.
The Significance of SPRAVATO®’s Standalone Approval
Editor: Dr. Carter, the FDA’s approval of SPRAVATO® as a standalone treatment is a major milestone. Can you explain why this is such a significant development?
Dr. Carter: Absolutely. Treatment-resistant depression affects about one-third of the 21 million adults in the U.S. with MDD. These patients often don’t respond to conventional treatments like oral antidepressants or psychotherapy. SPRAVATO® offers a novel approach that can provide relief where othre treatments have failed. It’s standalone approval underscores its efficacy and gives healthcare providers a powerful tool to help this underserved population.
Understanding esketamine and Its Mechanism
Editor: SPRAVATO®’s active ingredient is esketamine, which is related to ketamine. How does it work, and what sets it apart from traditional antidepressants?
dr. Carter: Esketamine is the mirror-image of ketamine,which has been used as an anesthetic for decades. Unlike traditional antidepressants that target serotonin or norepinephrine, esketamine works by increasing levels of glutamate, an excitatory neurotransmitter. This mechanism helps rapidly restore synaptic connections in the brain, which can improve mood and cognitive function. What’s remarkable is that patients may see improvements in symptoms as early as 24 hours, which is unprecedented in depression treatment.
Efficacy and Clinical Trial Results
Editor: The clinical trials showed a 22.5% remission rate at week 4 compared to 7.6% for the placebo group. How significant are these results?
Dr.Carter: These findings are highly significant.A remission rate of 22.5% means that nearly a quarter of patients experienced a complete resolution of their depressive symptoms. This is a ample advancement over the placebo group and demonstrates that SPRAVATO® can be a life-changing treatment for many. It’s notably encouraging for patients who’ve tried multiple therapies without success.
Administration and Safety Considerations
Editor: SPRAVATO® is administered as a nasal spray in a healthcare setting. why is this approach necessary, and what are the safety implications?
Dr. Carter: The nasal spray delivery ensures rapid absorption of the medication into the bloodstream. However, because esketamine can cause side effects like nausea, dissociation, and even hallucinations, it’s crucial that patients are monitored for at least two hours post-administration. The restricted access program also minimizes the risk of misuse,ensuring that only qualified patients receive the treatment in a controlled environment.
A New Path forward for Patients
Editor: How do you see SPRAVATO® changing the landscape of depression treatment?
Dr. Carter: SPRAVATO® represents a paradigm shift. For too long,patients with treatment-resistant depression have been left with limited options. This approval provides a new,effective treatment that doesn’t require daily medication,which can be a barrier for many. It’s a beacon of hope for those who’ve struggled to find relief and a reminder that innovative solutions are within reach.
Final Thoughts
Editor: Dr. Carter, thank you for sharing yoru insights. What would you say to individuals or families affected by treatment-resistant depression who are considering SPRAVATO®?
Dr.Carter: My message is one of hope. If you or a loved one has struggled with depression that hasn’t responded to traditional treatments, SPRAVATO® could be a game-changer. Speak with your healthcare provider to see if it’s the right option for you. Remember, help is available, and there’s no shame in seeking it.
