MGlu2/3 receptor antagonists produce antidepressant-like effects in animal models of depression. A number of mechanisms responsible for these actions are convergent to the mechanism of the fast antidepressant-like effect of ketamine. Furthermore, the data indicate that ketamine effect is related to the action of mGlu2 receptors and may be reduced by their agonists. The above facts became the...

Ketamine, a dissociative anaesthetic, has been used in the treatment of major depressive disorder (MDD) as a rapid acting antidepressant drug. Recent studies have shown that ketamine may increase the potential risk of treatment-induced mania in MDD patients. Lithium is a well-known mood stabilizer and has been widely used for the treatment of mania. It is not fully understood which forebrain...

Substance abuse disorder continues to have devastating consequences for individuals and society and current therapies are not sufficient to provide the magnitude of medical impact required. Although some evidence suggests the use of ketamine in treating various substance use related- symptoms, its adverse event profile including dissociation, dysphoria, and abuse liability limit its potential...

The robust antidepressant effects of (R,S)-ketamine are among the most important discoveries in mood research over the last half century. Off-label use of (R,S)-ketamine, which is an equal mixture of (R)-ketamine and (S)-ketamine, has become especially popular in the United States (US) for treatment-resistant depression. On March 5, 2019, the US Food and Drug Administration approved an...

Clinical and preclinical studies have demonstrated that depression, one of the most common psychiatric illnesses, is associated with reduced levels of neurotrophic factors, including brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF), contributing to neuronal atrophy in the prefrontal cortex (PFC) and hippocampus, and reduced hippocampal adult neurogenesis....

Conventional antidepressant medications, which act on monoaminergic systems, have significant limitations, including a time lag of weeks to months and low rates of therapeutic efficacy. Recently, clinical findings demonstrate that ketamine, a dissociative anesthetic that blocks N-methyl-d-aspartate (NMDA) receptor channel activity, causes rapid (within hours) and long-lasting (7 to 10 days)...

The N-methyl-d-aspartate receptor (NMDAR) antagonist (R,S)-ketamine produces rapid and sustained antidepressant effects in treatment-resistant patients with depression although intranasal use of (R,S)-ketamine in ketamine abusers is popular. In March 5, 2019, nasal spray of (S)-ketamine for treatment-resistant depression was approved as a new antidepressant by the US Food Drug Administration....

ABSTRACT Ketamine, an N‐methyl‐d‐aspartic acid receptor (NMDAR) antagonist, elicits rapid‐acting and sustained antidepressant effects in treatment‐resistant depressed patients. Accumulating evidence suggests that gut microbiota via the gut‐brain axis play a role in the pathogenesis of depression, thereby contributing to the antidepressant actions of certain compounds. Here we investigated the...

Methoxetamine (MXE) is an N-methyl-d-aspartate (NMDA) receptor antagonist that is chemically and pharmacologically similar to ketamine. Recently, there have been many reports regarding its use/misuse in humans which have resulted in serious or even fatal outcomes. Despite these reports, MXE is not controlled or regulated in many countries which may be partly due to the lack of scientific...

This study compared subjective and behavioral effect profiles of alcohol and smoked marijuana using technology that controlled puffing and inhalation parameters. Male volunteers (n = 5) with histories of moderate alcohol and marijuana use were administered three doses of alcohol (0.25, 0.5, or 1.0 g/kg), three doses of marijuana [4.8, or 16 puffs of 3.55% delta 9-tetrahydrocannabinol (THC)],...
