Ketamine Infusion Therapy: How Long Do Side Effects Last and What to Expect?

Recently, there has been increasing interest in Ketamine infusion therapy as a novel treatment option for patients suffering from treatment-resistant depression. This new type of therapy offers hope for those who are not responsive to traditional antidepressants. However, estimating the duration of therapeutic benefits and side effects of ketamine remains a difficult challenge for patients considering this treatment.

The Basics of Ketamine Infusion Therapy

Ketamine is mainly used as an anesthetic, but it has shown potent antidepressant effects. It acts through the blockade of the N-methyl-D-aspartate (NMDA) receptor, which is involved in the modulation of the mood. In addition, ketamine increases the level of brain-derived neurotrophic factor (BDNF) and stimulates the mTOR (mammalian target of rapamycin) pathway, both of which are involved in the processes of neural growth and repair.

Novel studies have also indicated that ketamine has some antiinflammatory activity, which correspondingly may augment its antidepressant effects. Since inflammation is associated with depression, the ability of ketamine to reduce inflammation might be another reason for its effectiveness in treating mood disorders.

How Ketamine Therapy Works in Treating Depression

Perhaps the most remarkable benefit of ketamine is it’s rapid relief of depressive symptoms, especially in patients who have not benefitted from other therapies. By influencing the functional connectivity and the activity of various neurotransmitters, ketamine can help decrease low mood, anhedonia, and even suicidal ideation.

Ketamine, besides from being studied for treatment of depression, is also being researched for chronic pain conditions such as fibromyalgia and neuropathic pain. Its analgesic properties, which help in the treating of persistent pain disorders, assist in changing one’s perception of pain.
