Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The registry is designed to systematically document adverse events, side effects, and patient-reported outcomes, providing a comprehensive assessment of both the short- and long-term effects of ketamine in psychopharmacology. By generating real-world evidence, this study shall contribute to a more nuanced understanding of ketamine's risk-benefit profile in clinical practice, particularly in subpopulations that are underrepresented in clinical trials. The findings prioritize the support for the refinement of treatment protocols and enhance patient safety in psychiatric care.

Study Groups

Major Depressive Disorder
Patients must have a Diagnostic and Statistical Manual 5 (DSM-5) diagnosis of Major Depressive Disorder (MDD), as determined by a psychiatrist.
Ketamine Hydrochloride
Ketamine, a N-methyl-D-aspartate (NMDA) receptor antagonist has been used for general anesthesia since the 1970s, however, reports and trials by the end of the twentieth century and onward using subanesthetic doses suggested robust and rapid antidepressant and anti-suicidal effects. Ketamine is available as a 50/50 racemic mixture of enantiomers (S)-ketamine and (R)-ketamine.Ketamine will be infused (slow IV infusions of ketamine (0.5 mg/kg) over 40 minutes) twice weekly over a period of 4 weeks) Ketamine will be given in intranasal spray twice weekly over a period of 4 weeks Ketamine will be given orally (solution 2.0mg/kg, 2.5mg/kg) twice weekly over a period of 4 weeks.
