Not just a treatment, but a worthy one

In his presentation at the virtual meeting of the American Psychiatric Association in 2021, Dr. Richard C. Shelton, Professor Charles B. Ireland in the Department of Psychiatry and Behavioral Neurobiology at the University of Alabama at Birmingham and Director of the UAB Depression and Suicide Center discuss the functions and concerns of ketamine.

“This is not just a treatment or a treatment to be taken lightly,” Shelton said during part of his Q + A presentation. “On the other hand, we have seen remarkable results.”

Shelton began by discussing the functions of ketamine in the brain and how it restores regulatory processes for patients with mood disorders, using, for example, a study by Li et al.1

“Stressful experiences cause thorns and synapses to shrink or recede. The brain is less able to control or regulate the emotional state, “Shelton explained.

With the administration of ketamine there is an almost immediate increase in the formation of critical vertebrate and synaptic proteins.

“When you add ketamine to the system, you produce a rapid return and recovery of these spines and synapses. We see an effect within 24 hours, ”Shelton continued. “Ketamine has the ability to restore regulatory control of the brain and helps to theoretically normalize mood.”

Shelton shared data from 8 studies on ketamine and how it produces a rapid, strong effect for patients with severe, resistant mood disorders.2-9 and additional studies on how ketamine works in patients with suicidal ideation.10-13

“The good news: ketamine seems to really work in these patients with high treatment resistance,” Shelton said.

Shelton also addressed key concerns about ketamine, especially how challenging it can be to prescribe. First, the US Food and Drug Administration requires a “somewhat cumbersome” risk assessment program and mitigation strategy in which the clinic, provider, and patient must be enrolled in the program. There are preliminary obstacles to resolution, as well as problems with cost recovery. Nevertheless, Shelton finds more ketamine than he deserves.

“When I treated my first patient with IV ketamine in 2012, it was just amazing to see the effect appear within 24 hours,” Shelton said.
