How Does Ketamine Work?

Living with severe mental illness or chronic pain is a glaring reality for many Americans. According to the National Institute of Mental Health, nearly 1 in 5 adults in the U.S. live with a diagnosable mental illness. On the other hand, the Centers for Disease Control and Prevention (CDC) reports that approximately 20% of adults in the U.S. live with some form of chronic pain.

This means that every day, millions of individuals struggle with debilitating symptoms that make it hard to function at work, care for loved ones, or enjoy life. And it doesn’t help that most traditional treatments for mental illness and chronic pain don’t always live up to expectations. This is where ketamine comes into the picture.

What is Ketamine? A Brief History

Ketamine is a medication that was originally developed as an anesthetic in the 1950s. Since then, it has been used extensively in medical settings for surgical procedures and pain management.

In the 1970s, ketamine was introduced as an illicit party drug, gaining widespread popularity for its hallucinogenic and dissociative effects. This led to its classification as a Schedule III controlled substance.

However, in recent years, ketamine has made a comeback in the medical field as a highly effective off-label treatment for severe depression, anxiety, chronic pain, and suicidal ideation.

Low-dose ketamine infusions have also demonstrated high efficacy in managing treatment-resistant mood disorders. Clinical trials show that up to 70 percent of people with treatment-resistant depression (TRD) experience rapid improvement in symptoms following ketamine treatment.

This makes ketamine therapy one of the most promising treatment options for people living with treatment-refractory mental illness and chronic pain. Some experts consider ketamine therapy the most significant discovery in mental health treatment in the last five decades.

Ketamine for Depression and Anxiety Treatment

Ketamine appears to work by inhibiting the N-methyl-D-aspartate receptor (NMDA) from binding with glutamate. The NMDA receptor is involved in learning and memory, as well as pain perception.

Inhibiting the NMDA receptor allows for an influx of glutamate, triggering a cascade of events that eventually leads to the growth of new neurons and synapses. This plasticity helps to reverse the negative changes in brain circuitry associated with depression and anxiety.

The result is a rapid improvement in mood. Ketamine also modulates the release of other neurotransmitters like dopamine and serotonin, effectively restoring the brain’s chemical balance. This further amplifies its mood-regulating effects.

Ketamine for Chronic Pain Management

The pain-relieving effects of ketamine are thought to be mediated by the same mechanism as its antidepressant effects. By restoring synaptic plasticity and communication between neurons, ketamine therapy can help reverse central sensitization which is associated with the development of chronic pain. Ketamine has also displayed anti-inflammation properties, which may bolster its efficacy in treating chronic pain.

Who can Benefit from Ketamine Therapy?

Ketamine is not a first-line treatment for mental illness or chronic pain. However, it can be an effective alternative treatment for people who have not responded to other treatments. Ketamine therapy is typically recommended for people who have:

  • Tried multiple medications without relief
  • Not responded to traditional talk therapy
  • Had adverse reactions to other medications

However, not everyone is a good candidate for ketamine therapy. People with a history of certain medical conditions like heart disease, uncontrolled hypertension, and pregnant or breastfeeding women should not receive ketamine treatment.

Other contraindications include psychosis, increased intracranial pressure, and substance use disorders. Your doctor will conduct a comprehensive assessment of your medical history to determine if ketamine therapy is right for you.

Final Thoughts

Ketamine therapy is a cutting-edge treatment that is setting a new standard for the management of chronic mental illness and pain. It offers a much-needed alternative for people who have not found adequate relief from traditional treatments.

If you or someone you know is struggling with mental illness or chronic pain, ketamine therapy is an option worth exploring. Talk to your doctor about whether ketamine could be right for you.
