Frequently Asked Questions about Ketamine Infusion Therapy

  1. Administration: Ketamine is administered through an IV line, which allows for precise control over the dosage and rate of infusion. This is typically done in a medical setting, such as a clinic or hospital, under the supervision of trained healthcare professionals.
  2. Dosage and Duration: The dosage and duration of the infusion depend on the specific condition being treated and the patient’s individual response to ketamine. The healthcare provider will determine the appropriate dosage based on factors like body weight, medical history, and the severity of the condition.
  3. NMDA Receptor Modulation: Ketamine is known to act on the brain’s NMDA (N-methyl-D-aspartate) receptors. It blocks these receptors and, at higher doses, leads to a dissociative state, where the patient may feel disconnected from their body or reality. This property of ketamine is believed to be a key mechanism in its therapeutic effects.
  4. Neuroplasticity and Brain Connectivity: Ketamine has been shown to induce changes in the brain that may promote neuroplasticity, the brain’s ability to form new neural connections. These changes could be important in the treatment of mood disorders and chronic pain conditions.
  5. Rapid Onset: One of the significant advantages of ketamine infusion therapy is its relatively rapid onset of action. Patients often experience effects within minutes to hours after the infusion, compared to traditional antidepressant medications that may take weeks to show noticeable effects.
