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. They have been the subject of extensive research for 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, like SSRIs, and therapy.

Due to the success Ketamine have had in treating Major Depressive Disorder (MDD), it was inevitable that a version of it would be created for FDA approval. Because Ketamine is a generic drug that cannot be patented, pharmaceutical companies explored small variations of the Ketamine molecule that could also be effective for treating depression.
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 nasal spray for their treatment of MDD.
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. Esketamine is isolated to only contain S-Ketamine, which makes Spravato™ unique.
Early scientific evidence suggests that while both are effective treatments, but IV Ketamine infusions of racemic Ketamine may present better outcomes. “Intravenous ketamine appears to be more efficacious than intranasal esketamine for the treatment of depression.” (Journal of Affective Disorders)
