Ketamine Infusions

Ketamine infusions are a reliable treatment for Major Depressive Disorder (MDD) and have been proven to be a successful treatment option for 70% of treatment-resistant patients. Ketamine has been the subject of extensive research over the last 17 years. Its high success rate and lack of side effects makes it the most promising treatment for the tens of millions of people who cannot find relief from standard anti-depressants such as SSRIs, or therapy alone, and paved the way for Spravato™ to be created.

What Is Spravato? – Meet The Esketamine Nasal Spray

Due to the success Ketamine has had in treating Major Depressive Disorder (MDD), it was inevitable that a more easily deliverable version would be created for FDA approval. Because Ketamine is a generic drug that has existed since the 1960’s, pharmaceutical companies explored small variations of the Ketamine molecule that could also be effective for treating depression. Enter Spravato!

In 2019, the Esketamine nasal spray Spravato was approved by the FDA for the treatment of MDD that is treatment resistant or includes suicidal thoughts. With its approval, patients now have the choice between Ketamine IV infusions and esketamine treatments in the form of a nasal spray for MDD. When deciding on Spravato vs ketamine, there are a few differences to consider, below.

What Are the Differences Between Ketamine and Esketamine Treatments?

“What is the difference between Ketamine and Esketamine” is a question we often hear. There are two different types of Ketamine: R-Ketamine and S-Ketamine. While they are nearly identical molecules, they have slightly different effects on the brain. The type of Ketamine used in IV infusions is racemic, which means that is a mixture of R-Ketamine and S-Ketamine. Meanwhile, Esketamine is isolated to only contain S-Ketamine, which makes Spravato unique for Esketamine treatments.

Early scientific evidence suggests that both are effective treatments.  IV Ketamine infusions of racemic Ketamine may present better outcomes due to a number of factors including delivery method, dosage, and chemistry. Intravenous ketamine appears to be more efficacious than intranasal Esketamine for the treatment of depression.” (Journal of Affective Disorders)
