millions of americans — more than 16 million, to be exact — suffer from major depressive episodes each year, about a third of whom do not respond to antidep
ketamine is a versatile agent primarily utilized as a dissociative anesthetic, which acts by blocking the excitatory receptor n-methyl-d-aspartate receptor (nmda). it functions to inhibit the current of both na+ and k+ voltage-gated channels, thus preventing serotonin and dopamine reuptake. studies have indicated that administering a single subanesthetic dose of ketamine relieves depression rapidly and that the effect is sustained. for decades antidepressant agents were based on the monoamine theory. although ketamine may not be the golden antidepressant, it has opened new avenues toward mechanisms involved in the pathology of treatment-resistant depression and achieving rapid antidepressant effects. thus, preclinical studies focusing on deciphering the molecular mechanisms involved in the antidepressant action of ketamine will assist in the development of a new antidepressant. this review was conducted to elucidate the emerging pathways that can explain the complex dose-dependent mechanisms achieved by administering ketamine to treat major depressive disorders. special attention was paid to reviewing the literature on hydroxynorketamines, which are ketamine metabolites that have recently attracted attention in the context of depression.

although the efficacy of racemate ketamine, a rapid onset and sustained antidepressant, for patients with treatment-resistant depression was a serendipitous finding, clinical use of ketamine is limited, due to psychotomimetic side effects and abuse liability. behavioral and side-effect evaluation tests were applied to compare the two stereoisomers of ketamine. to elucidate their potential therapeutic mechanisms, we examined the effects of these stereoisomers on brain-derived neurotrophic factor (bdnf)–trkb signaling, and synaptogenesis in selected brain regions. in the social defeat stress and learned helplessness models of depression, r-ketamine showed a greater potency and longer-lasting antidepressant effect than s-ketamine (esketamine). furthermore, r-ketamine induced a more potent beneficial effect on decreased dendritic spine density, bdnf–trkb signaling and synaptogenesis in the prefrontal cortex (pfc), ca3 and dentate gyrus (dg) of the hippocampus from depressed mice compared with s-ketamine. however, neither stereoisomer affected these alterations in the nucleus accumbens of depressed mice. in behavioral tests for side effects, s-ketamine, but not r-ketamine, precipitated behavioral abnormalities, such as hyperlocomotion, prepulse inhibition deficits and rewarding effects. in addition, a single dose of s-ketamine, but not r-ketamine, caused a loss of parvalbumin (pv)-positive cells in the prelimbic region of the medial pfc and dg. these findings suggest that, unlike s-ketamine, r-ketamine can elicit a sustained antidepressant effect, mediated by increased bdnf–trkb signaling and synaptogenesis in the pfc, dg and ca3. r-ketamine appears to be a potent, long-lasting and safe antidepressant, relative to s-ketamine, as r-ketamine appears to be free of psychotomimetic side effects and abuse liability.

anesthetic to antidepressant
ketamine is associated with rapid antidepressant effects and temporary dissociative experiences, and this review examines whether these dissociative symptoms are necessary for antidepressant efficacy. although the current literature does not support this relationship, further work is needed to explore possible associations at the molecular, biomarker, and psychological levels.
background major depressive disorder (mdd) is the most disabling and burdensome mental disorder, negatively affecting an individual’s quality of life and daily functioning. the current study was conducted with the aim of investigating the clinical effects of intravenous ketamine on symptoms of mdd and suicidal ideation. methods the current randomized clinical trial was carried out on 64 patients diagnosed with treatment-resistant major depressive disorder between april and august 2022. the participants were randomly assigned to two groups: the intervention group received a dose of 0.5 mg/kg of ketamine, while the control group received normal saline. the montgomery-asberg depression scale and beck’s suicidal ideation scale were utilized to assess depression and suicidal ideation, respectively. results one hour after the administration of ketamine treatment, there was a notable and significant improvement in both depression symptoms (35.16 ± 8.13 vs. 14.90 ± 10.09) and suicidal ideation (6.74 ± 6.67 vs. 0.42 ± 1.52). moreover, there were statistically significant differences in depression scores between the two groups at one hour, four hours, one day, three days, one week, one month, and two months after the administration of ketamine (p-value < 0.001). however, ketamine recipients frequently experienced side effects such as increased heart rate, headache, dizziness, and dissociative syndrome symptoms. conclusion the observed rapid onset of action and sustained effect demonstrate the potential of ketamine to provide relief from depressive symptoms in a shorter timeframe compared to traditional treatment approaches. these findings contribute to the growing body of evidence supporting the use of ketamine as a valuable therapeutic option for patients with treatment-resistant depression. irct registration irct registration number: irct20210806052096n1; irct url: https://www.irct.ir/trial/62243 ; ethical code: ir.zums.rec.1400.150; registration date: 2022-04-09.

the growing interest in the rapid and sustained antidepressant effects of the dissociative anesthetic ketamine and classic psychedelics, such as psilocybin, is remarkable. however, both ketamine and psychedelics are known to induce acute mystical experiences; ketamine can cause dissociative symptoms such as out-of-body experience, while psychedelics typically bring about hallucinogenic experiences, like a profound sense of unity with the universe or nature. the role of these mystical experiences in enhancing the antidepressant outcomes for patients with depression is currently an area of ongoing investigation and debate. clinical studies have shown that the dissociative symptoms following the administration of ketamine or (s)-ketamine (esketamine) are not directly linked to their antidepressant properties. in contrast, the antidepressant potential of (r)-ketamine (arketamine), thought to lack dissociative side effects, has yet to be conclusively proven in large-scale clinical trials. moreover, although the activation of the serotonin 5-ht2a receptor is crucial for the hallucinogenic effects of psychedelics in humans, its precise role in their antidepressant action is still under discussion. this article explores the importance of mystical experiences in enhancing the antidepressant efficacy of both ketamine and classic psychedelics.
