What is Ketamine IV?
Definition and how it works
Ketamine is a dissociative anaesthetic that at sub-anaesthetic doses acts as an NMDA receptor antagonist, producing rapid-onset (within hours) antidepressant, anxiolytic and neuroplastic effects. IV ketamine infusion at 0.5 mg/kg over 40 minutes is the standard for treatment-resistant depression. In longevity and mental health, its potential for neuroplasticity, PTSD treatment, chronic anxiety and chronic pain is actively investigated.
Origin and history
Ketamine was synthesised by Calvin Stevens in 1962 and FDA-approved as an anaesthetic in 1970. Its antidepressant use was discovered serendipitously in the late 1990s. The first controlled studies of IV infusion for depression were published by the NIMH in 2006, marking a milestone in psychopharmacology.

The science behind Ketamine IV
Scientific evidence summary
The FDA approved intranasal esketamine (Spravato) in 2019 for treatment-resistant depression. Studies from the Yale Mood Disorders Research Program confirm antidepressant response in 70% of patients with treatment-resistant depression after IV infusions. The mechanism includes NMDA antagonism, AMPA/mTOR activation and rapid synapse formation in the prefrontal cortex. Effects on BDNF and prefrontal synapses persist beyond the drug's presence in the body.
