Ketamine infusion therapy has emerged as a promising option within modern psychiatric treatment. However, you may have questions about this treatment and how it works. This guide explains what the treatment entails, how it works, what to expect during a clinic visit, and the potential benefits and risks.
Ketamine infusion therapy refers to the intravenous (IV) administration of low, subanesthetic doses of ketamine in a controlled medical setting. The treatment is commonly used off-label for major depressive disorder that has not responded to conventional antidepressants, also known as treatment-resistant depression (TRD). Psychiatrists can also use it to treat bipolar disorder and post-traumatic stress disorder (PTSD). Clinics that offer infusion therapy operate under psychiatric oversight and follow protocols to carefully select patients for treatment and monitor them throughout the process.
At therapeutic doses, ketamine acts primarily as an N-methyl-D-aspartate (NMDA) receptor antagonist. It binds to these receptors, increasing the amount of the neurotransmitter glutamate in the spaces between neurons. Glutamate then activates connections in the AMPA receptor. Together, the block of the NMDA and the activation of the AMPA receptors lead to the release of molecules that help neurons communicate along new pathways.
This process, known as synaptogenesis, affects the patient's mood, thought, and cognition. While research is ongoing about the long-term effects of ketamine infusion, its short-term effects produce rapid changes in mood and suicidal ideation for some patients, often within hours of administration. In contrast, traditional antidepressants usually require weeks to take effect.
The benefits of ketamine and its related compounds may include rapid relief from depressive symptoms and a reduction in suicidal thoughts for certain patients. In some cases, the effects are observable within hours to days following an infusion. However, treatment outcomes can vary widely among individuals depending on factors such as the severity of the their symptoms, individual biology, and the specific context of treatment.
When administered by a qualified psychiatrist, ketamine-infusion therapy is considered relatively safe. However, as with any treatment, there are potential risks and complications. Common side effects of ketamine-infusion therapy include:
In most cases, these side effects will resolve on their own after the treatment session. However, there are rare but serious risks, such as bladder damage and the potential for misuse if used without professional supervision.
A typical ketamine infusion therapy session begins with a psychiatric evaluation and basic medical screening. During the infusion, the clinical team will continuously monitor the patient's vital signs. Ketamine infusion treatment sessions commonly last around 40 to 60 minutes, with observation for at least an hour afterward to ensure stable cardiovascular and mental status. Depending on the patient's treatment plan, the psychiatrist may recommend multiple infusions over several weeks to achieve and maintain symptom relief.
