Near the end of life, many people will face depression, anxiety, and pain as they grapple with the precious time that remains. For patients on hospice, it is understood that without major medical interventions they will likely have less than 6 months left to live. The fear of death and the discomfort that may be encountered in the months to weeks remaining can lead to an existential crisis where we find ourselves questioning the meaning and purpose of our lives.
Emerging research has suggested that Ketamine appears highly effective in treating a variety of psychological conditions found at the end of life including depression, anxiety, and the existential crisis. Additionally it functions as a potent pain reliever. With this combination of effects, ketamine may be the optimal medication for treatment of patients at the end of life.
In recent decades, modern medicine has focused on ways to mitigate both the physical and psychological discomfort surrounding death. Currently available treatments for patients on hospice include narcotics, sedatives, and antidepressants. In many ways these medications focus on treating the symptoms at the end of life rather than confronting the underlying fears many of us will have in our final days. Ketamine’s unique effects help patients at the end of life delve deeper beneath the symptoms, allowing them time to examine their own existential questions more effectively than ever before.
In the following sections, we will examine the role of ketamine in this critical phase of healthcare at the end of life, exploring its benefits, effectiveness, and potential for the future.
Ketamine is likely the most commonly used anesthetic worldwide and has been on the World Health Organization’s list of essential medications since 1985.
Its use, however, extends beyond its anesthetic properties. Over the years, researchers have discovered ketamine’s potential in managing pain, particularly chronic and neuropathic pain, making it a useful tool in fields ranging from palliative care to emergency medicine. More recently, it has garnered attention for its rapid-acting antidepressant and anti-anxiety effects, offering hope for patients with treatment-resistant mood disorders.
Ketamine operates as an N-methyl-D-aspartate (NMDA) receptor antagonist. The NMDA receptor plays a key role in neural signaling and brain function. When ketamine binds to this receptor, it disrupts the normal flow of signals, inducing a relaxed, trance-like state, pain relief, and even mystical experiences at higher doses. Furthermore, by blocking the NMDA receptor, ketamine prompts a cascade of reactions in the brain that encourage synaptic growth and improve connectivity between neurons. This “neuroplastic” effect appears to underlie its rapid and sustained impact on mood disorders.
In the following sections, we’ll delve deeper into the application of ketamine for pain management, anxiety, and depression, especially in end-of-life care scenarios.
Pain, both chronic and acute, is a common symptom in end-of-life care. Chronic pain, which is long-lasting and persistent, can be a result of the primary illness or its treatment, such as cancer or its associated therapies. Acute pain, on the other hand, is often a result of injury or surgical procedures, and while it typically has a shorter duration, it can be intense and equally disruptive. Management of these types of pain is a critical component of end-of-life care, aiming to improve the quality of life for patients during their final days.
Ketamine plays a unique role in pain management due to its distinctive mechanism of action. As an NMDA receptor antagonist, ketamine reduces the excitability of neurons, thereby decreasing the transmission of pain signals in the brain and spinal cord. This can result in significant relief from both acute and chronic pain, particularly in cases where opioids and other analgesics are ineffective or not tolerated.
In addition, ketamine has been shown to help manage opioid tolerance and hyperalgesia (an increased sensitivity to pain), common issues in long-term pain management. By offering a different pathway for pain relief, ketamine can reduce the overall dependence on opioids, reducing potential side effects and improving overall pain control.
Research supports the use of ketamine for pain management in end-of-life care. A systematic review published in the Journal of Pain and Symptom Management in 2020 found that subanesthetic doses of ketamine could provide substantial pain relief in palliative care patients, with manageable side effects. Another study published in the Journal of Palliative Medicine in 2012 showed that low-dose ketamine resulted in significant improvement in pain scores for hospice patients, contributing to their overall comfort and quality of life.

As individuals near the end of their lives, anxiety can become a significant challenge. The symptoms can vary in intensity and nature, but common manifestations often include:
The effects of these symptoms can greatly affect a patient’s quality of life, underscoring the need for effective management strategies.
Ketamine’s role in anxiety management stems from its unique effects on the brain. By blocking the NMDA receptors, ketamine creates a rapid anti-anxiety effect. It enhances neuronal connectivity and promotes the growth and development of new neural connections, processes that are believed to alleviate anxiety symptoms.
In a recent meta-analysis, injectable forms of ketamine were found to rapidly improve patient’s symptoms of anxiety within minutes to hours.
The use of ketamine for managing anxiety in end-of-life care has shown promising results in a study that examined the use of oral ketamine as an anxiety treatment for hospice patients over a 28-day period. Remarkably, a significant reduction in anxiety was observed in a majority of patients by day 3, with the improvement persisting throughout the trial. All the trial completers responded positively to ketamine for anxiety.
These promising findings spotlight ketamine’s potential as a potent, fast-acting solution for anxiety in end-of-life care. In the next section, we will explore how ketamine may also provide a critical treatment for depression in this challenging period.
Depression, a prevalent issue in end-of-life care, can profoundly impact a patient’s quality of life. Symptoms of depression can include:
These symptoms can intensify physical discomfort, further undermine the quality of life, and potentially influence a patient’s desire for hastened death.
Ketamine has emerged as a potent solution for treating depression, even in cases resistant to conventional treatments. Ketamine’s action in blocking NMDA receptors sparks a series of reactions in the brain leading to the growth of new synaptic connections and enhanced neural connectivity. This process is believed to provide rapid relief from depressive symptoms, often noticeable within hours of administration.
A growing body of research supports the use of ketamine in treating depression. Notably:
The current views on the use of ketamine in end-of-life care within the medical community are largely positive, largely due to its multi-faceted benefits. Physicians appreciate ketamine’s versatility in managing not just pain, but also mental health symptoms like depression and anxiety, which are often prevalent in end-of-life situations.
The promise of ketamine as an effective treatment option in end-of-life care is certainly encouraging. However, as we continue to explore its potential, it’s crucial to ensure the research is robust, the application is ethical, and the benefits to patients are real and significant. By doing so, we can offer better care for those in the final stages of life, improving their comfort and quality of life.
