New research has recently presented how ketamine, which is used as an anti-depressant, might be effective in practice. Those who have chronic suicidality provided fast relief through regularly administering the drug in clinical backgrounds.
In relation to this, the use of the said treatment to treat depression recently steam on the back of an informative study that has exhibited how it can suppress the so-called 'anti-reward' center of the brain, mend damaged neural circuits and interrelate with "serotonin receptors" to strengthen the emission of dopamine.
According to a New Atlas report, among the many different studies to investigate the antidepressant effects of ketamine was a work that came out in 2017 with a focus specifically on suicidal patients, "the first to do so."
The study investigators discovered that "low-dose infusions of ketamine" resulted in a major reduction in suicidal thoughts 24 hours later. It also had positive impacts on fatigue, depression, and mood that lasted for roughly six weeks.
Focus on Acute Suicidality Sufferers
This new research conducted at the Australia-based University of the Sunshine Coast again focuses on acute suicidality sufferers. The research team hopes to build on a past study that has presented the anti-depressant potential when administered through injection.
According to Dr. Adem Can, the study's principal investigator, "intravenous administration though intrusive, costly, and it also carries a greater chance of negative reactions because of its injection "straight into the bloodstream."
Consequently, Can added, logically, it is quite simpler and more rapid to administer oral medication clinically.
The research engaged 32 adults who were sufferers of chronic suicidal thoughts and were provided with ketamine orally for a period of six weeks.
The subjects were evaluated through the use of standard scales for suicidal thoughts and depressive symptoms.
As a result, 69 percent of the participants showed clinical improvement during the six-week-period. On the other hand, fifty percent of them still reported considerable improvements four weeks following administration of their final dose.
A Substantial Reduction in Suicide Ideation
Averagely, patients experienced a substantial reduction in suicide ideation, from a high level before the test to below the clinical verge by the sixth week of trial, explained Dr. Can.
In medicine, such a response rate is substantial, explained the principal investigator adding, "specifically given it was experienced" by those who have chronic suicidality, which can be challenging for a treatment.
This new research is essentially small, although the team is inspired by the results, specifically due to the range of afflictions that the subjects experienced resulting in their suicidal thoughts, which included "depression, anxiety, and borderline personality disorder.
Professor Jim Lagopoulos, the study supervisor, said, "Yet the treatment still worked across the group." He added this means the trial group was the community's representative being served, "where one or more other situations frequently accompany suicidality.
Therefore, results such as these through the spectrum, the study supervisor elaborated, "are quite encouraging."
The researchers do note, though, that more studies are needed for further exploration of the efficacy of oral doses of ketamine "across randomized control groups." This study came out in the Translational Psychiatry journal.
