Ketamine, a non-competitive N-Methyl-D-Aspartate receptor antagonist, was approved for use with Treatment-Resistant Depression (TRD) and is currently in clinical trials for treating substance use disorder (SUD), and Post Traumatic Stress Disorder. However, ketamine is an addictive drug, and thus we need to better understand ketamine's mechanism of action in addiction to reliably assess the...

Background: Effective pharmacotherapies for Alcohol Use Disorder (AUD) are lacking, and factors such as sex, drinking patterns, and timing of treatment during the addiction cycle may influence treatment efficacy. Clinical studies suggest that ketamine may be effective in AUD; however, preclinical findings have been inconclusive, likely due to varying rodent strains, intake protocols, and...

While ketamine, an NMDA receptor antagonist, is effective in treating major depression, studies have not addressed the safety of repeated ketamine infusions in depressed patients with comorbid alcohol use disorder (AUD). In this study, we aimed to determine whether a history of chronic social isolation and alcohol exposure alter the reinforcing properties of ketamine in male and female rats....

Ketamine (KET), a non-competitive N-methyl-d-aspartate (NMDA) receptor antagonist, has rapid onset of antidepressant effects in Treatment-Resistant Depression patients and repeated infusions are required to sustain its antidepressant properties. However, KET is an addictive drug, and so more preclinical and clinical research is needed to assess the safety of recurring treatments in both sexes....

Subanesthetic ketamine (KET) elicits rapid, robust, but transient antidepressant effects. KET's antidepressant actions can be augmented and maintained for a longer duration when repeatedly delivered. However, KET is recreationally abused, raising long-term treatment safety concerns. Women are more likely than men to seek treatment for depression, escalate from casual to compulsive drug use, and...

Background Ketamine has rapid antidepressant effects and shows great promise as a novel treatment for depression, but its limitations including its abuse potential are poorly understood. Given that the prevalence of depression is twice as high in women as in men and that depression and substance use disorders are highly comorbid, we hypothesized that a sex-specific responsivity to behavioral...

Recent work from our group and others has revealed a higher sensitivity of female rodents to the antidepressant-like effects of the N-methyl d-aspartate receptor antagonist ketamine strongly influenced by circulating estrogen and progesterone levels. However, in the absence of any preclinical studies of pharmacokinetic sex differences using low-dose ketamine in rats, it is unclear whether the...

Sub-anesthetic ketamine produces rapid antidepressant effects in patients with bipolar and unipolar major depression where conventional monoaminergic-based antidepressant drugs have been ineffective or ridden with side effects. A single ketamine infusion can produce antidepressant effects lasting up to two weeks, and multiple ketamine infusions prolong this effect. Pre-clinical studies are...

In this review, we will discuss the safety of repeated treatments with ketamine for patients with treatment-resistant depression (TRD), a condition in which patients with major depression do not show any clinical improvements following treatments with at least two antidepressant drugs. We will discuss the effects of these treatments in both sexes at different developmental periods. Numerous...
