Effects of ketamine

Ketamine is a powerful anesthetic that has been used for more than 50 years to relieve pain and perform surgery. In recent years, however, there has also been much interest in the psychoactive effects of ketamine, which can help treat depression, anxiety and other mental disorders. In this article, we will discuss how ketamine works and its effects on the body and mind.

How does ketamine work?

Ketamine acts on the central nervous system and affects the activity of several neurotransmitters, including glutamate, dopamine and serotonin. It is an NMDA receptor antagonist, which means it blocks the action of the NMDA receptor in the brain. The NMDA receptor is an important type of glutamate receptor involved in learning processes and memory formation.

By blocking the NMDA receptor, ketamine reduces the activity of the glutamate neurotransmitter. This can lead to reduced communication between different parts of the brain and decreased sensitivity to pain. Ketamine also affects the dopamine and serotonin systems in the brain, which are involved in emotion regulation and reward behavior.

Effects of ketamine

The effects of ketamine depend on the dose and method of administration. At low doses, such as in pain management or anesthesia, ketamine can cause a sensation of numbness and a slight reduction in consciousness. At higher doses, however, hallucinogenic and dissociative effects can occur, which is why ketamine is also used recreationally.

The dissociative effects of ketamine are often described as a feeling of separation between body and mind. People can feel themselves floating outside their own bodies and experience an altered sense of time. It can also lead to distorted sensory perception, such as changing colors and shapes or hearing sounds that are not there.

However, ketamine’s hallucinogenic effects can also carry risks, such as losing touch with reality or experiencing frightening visions. Therefore, it is important that ketamine be used only under the supervision of a qualified physician or therapist.

Ketamine and depression

One of the most promising uses of ketamine is the treatment of depression. Research has shown that a single dose of ketamine can significantly reduce depressive symptoms within a few hours. It seems to be especially effective in people who do not respond to traditional antidepressants.

The exact action of ketamine in depression is not yet fully understood, but it appears to be related to its effects on the glutamate system in the brain. Depression is often associated with decreased glutamate function, which can lead to decreased neural plasticity and impaired communication between different brain regions. Ketamine can counteract these effects by increasing the activity of the glutamate system.

Moreover, ketamine appears to stimulate the production of BDNF (brain-derived neurotrophic factor), a protein involved in the growth and survival of neurons in the brain. Reduced BDNF production is associated with depression, so stimulation of BDNF by ketamine may contribute to its antidepressant effects.

Although ketamine shows promise as a treatment for depression, there are still concerns about its long-term effects and potential for abuse.

Ketamine and anxiety

As with depression, ketamine also appears to be effective in treating anxiety disorders. Anxiety disorders are often associated with increased activity in the limbic system, a brain region involved in emotion regulation. Ketamine can reduce this excessive activity and restore communication between different brain regions.

There is also evidence that ketamine can strengthen connections between neurons and promote the growth of new neurons. This can contribute to the brain’s ability to adapt and recover from stress and trauma.

Ketamine and addiction

Interest in the use of ketamine in the treatment of addictions has also emerged. Although its exact effects are not yet fully understood, ketamine appears to help reduce cravings and improve emotion regulation in people with addiction problems.

However, much research is still needed before ketamine can be recommended as a treatment for addictions. There are also concerns about the risk of addiction and abuse in the recreational use of ketamine.


Ketamine is a powerful anesthetic that can also have psychoactive effects at higher doses. It acts on the central nervous system and affects the activity of several neurotransmitters, including glutamate, dopamine and serotonin. Ketamine can be effective in treating depression, anxiety and addictions….
