Ketamine's Role in Revolutionizing Treatment for Resistant Depression
When Dr. Danish first introduced Intravenous (IV) Ketamine as a treatment option for depression in the region, it marked the beginning of a new era in psychiatric care. Continuously striving to remain at the forefront of innovative treatments, Dr. Danish and his team at Philadelphia Integrative Psychiatry have since kept a keen eye on the evolving landscape of ketamine and esketamine therapies. The following blog looks at various aspects of ketamine for depression, including mechanism, dosing, forms of administration, efficacy, and side effects.
Overview of Ketamine's Mechanism in Depression Treatment
Ketamine, initially used as an anesthetic, is increasingly recognized for its rapid antidepressant effects, particularly in treatment-resistant depression. Unlike traditional antidepressants that target the monoaminergic system and may take weeks to exert effects, ketamine acts on the glutamatergic system. It modulates glutamate, a key neurotransmitter involved in mood regulation, by blocking N-methyl-D-aspartate (NMDA) receptors. This blockade leads to an increase in glutamate release and subsequent activation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors. The activation of AMPA receptors is thought to initiate a cascade of events that result in the rapid production of brain-derived neurotrophic factor (BDNF), enhancing neuroplasticity and potentially reversing the synaptic deficits commonly observed in depression.
Administration and Dosage
Ketamine is administered through various routes, including intravenous (IV) infusion, intramuscular injection, subcutaneous injection, oral troche, and intranasal spray. The dosage and frequency of administration are tailored to individual patient needs, based on factors such as weight, severity of symptoms, and response to previous treatments. This personalized approach helps maximize the efficacy of the treatment while minimizing side effects.
Rapid Onset of Action
One of the most significant advantages of ketamine in the treatment of depression is its rapid onset of action. Patients often report experiencing relief from depressive symptoms within hours to days after treatment, which is a critical benefit for those suffering from severe and acute episodes of depression. This rapid response can be particularly life-saving for individuals experiencing intense suicidal ideation.
Maintenance and Follow-Up
To sustain the antidepressant effects of ketamine, periodic booster sessions are usually necessary. Regular monitoring and follow-up consultations with healthcare providers ensure the safety and effectiveness of the treatment over time. These sessions also provide an opportunity to adjust the treatment plan as needed, based on the patient's ongoing response and any side effects they may experience.

Hope for Treatment-Resistant Depression
Ketamine presents a beacon of hope for individuals grappling with treatment-resistant depression, offering a viable alternative when traditional antidepressants fail. It can be integrated with other therapeutic strategies, including psychotherapy, to create a holistic treatment plan for depression. Additionally, numerous studies have documented ketamine's rapid and significant reduction in suicidal ideation, further underscoring its potential in critical psychiatric interventions.
Extensive research supports the strong efficacy and relatively favorable side effect profile of ketamine in the treatment of depression. A significant review conducted in 2021 emphasized that ketamine not only rapidly alleviates depressive symptoms but also maintains these effects over time, positioning it as a formidable alternative to conventional treatments. Importantly, the review revealed that ketamine surpasses electroconvulsive therapy (ECT)—previously deemed the most effective option for treatment-resistant depression (TRD)—while inducing fewer cognitive side effects, highlighting its transformative potential for patients with TRD.
Safety Profile and Side Effects
While ketamine is generally safe when administered under medical supervision, it can cause side effects such as nausea, transient increases in blood pressure, and dissociative experiences. However, these effects are typically mild and resolve quickly. Ensuring that ketamine is administered in a controlled medical setting helps manage these side effects effectively.

Rare Side Effects:
Long Term use and/or over-use of ketamine can lead to unique and more chronic concerns, including smooth muscle dysfunction. Examples of this include tinnitus, bladder dysfunction, and esophageal motility concerns.
