The recent approval of the nasal spray Spravato by the U.S. Food and Drug Administration (FDA) marks a significant milestone in the treatment of Major Depressive Disorder (MDD), particularly for patients who have not responded to traditional oral antidepressants. This innovative therapy offers hope to approximately 21 million adults in the U.S. who have experienced at least one major depressive episode, with one-third classified as having treatment-resistant depression.
Spravato is specifically designed for individuals suffering from MDD who have failed to achieve relief after trying at least two different oral antidepressants. This approval comes at a time when the prevalence of MDD in the United States continues to rise, with rates nearly doubling over the past two decades. The FDA's decision to approve Spravato provides a new avenue for healthcare providers seeking quicker solutions for their patients, which is crucial given that conventional treatments can take weeks to show effects.
The mechanism of action for Spravato is noteworthy; it targets pathways in the brain that influence glutamate, a neurotransmitter responsible for regulating mood. Clinical trials led by Dr. Gregory Mattingly of the Midwest Research Group revealed promising results. By the fourth week of the study, 22.5% of participants who received an 84 mg dose of Spravato achieved remission, while 18.3% of those on a 56 mg dose also reached remission. In comparison, only 7.6% of participants taking a placebo experienced similar outcomes.
“Major depression is one of the greatest health challenges in the U.S., as approximately 21 million adults have had at least one major depressive episode and approximately one-third are considered to have challenging-to-treat depression.”

Remission was defined using the Montgomery-Åsberg Depression Rating Scale (MADRS), requiring a total score of less than or equal to 12. This new treatment option not only offers a faster alternative but also allows healthcare professionals to personalize treatment plans more effectively. Dr. Mattingly emphasized, “This approval gives patients and healthcare professionals the freedom to further personalize treatment plans and options to determine the best way to incorporate Spravato into their care — either alone or in conjunction with an oral antidepressant.”
Alcera, a key figure in the discussions surrounding this approval, stated that this decision represents a critical step forward for those battling major depression disorders. He highlighted that “the FDA approval allows prescribers a new path in treating patients with a faster alternative than traditional treatments, which can often take weeks to provide relief for those suffering from depression.”
The economic burden of major depression is substantial, ranking among the highest for psychiatric disorders. The introduction of effective treatments like Spravato could alleviate some of this financial strain on both patients and healthcare systems.

Patients have reported transformational changes in their lives after beginning treatment with Spravato. Alcera noted that “having new innovative therapies, like Spravato, offers hope to those who are suffering from treatment-resistant depression.” The development of additional forms of Spravato, including potential oral versions, is currently being explored to better cater to patients who may find intranasal administration challenging.
