Abstract Since 2006, there has been a resurgent interest in the pharmacology and therapeutics of psychedelic drugs. Psilocybin, the 4‐phosphoryl ester of N,N ‐dimethyltryptamine (DMT), has been studied most often, but DMT itself is also appealing because of its brief but profound psychological effects and its presence as an endogenous substance in mammalian brain. Although there have been a few...
Ketamine, an anesthetic developed in the early 1960s, is also a popular abused drug among young people at dance parties and raves and among spiritual seekers, because it produces schizophrenia-like symptoms and dissociation (i.e., out-of-body experience). Regarding mood disorders, ketamine exerts robust antidepressant actions in treatment-resistant patients with depression. Ketamine is a...

Exposure to organophosphates (OP) during the First Gulf War is among one of the factors for Gulf War Illness (GWI) development in veterans and it has been challenging to treat GWI symptoms with existing therapies. Ketamine produces a rapid-onset and sustained antidepressant response, but there is no evidence whether ketamine treatment is effective for GWI depression. Repeated, low-dose exposure...

Background and Aims: 3, 4- methylenedioxymethamphetamine (MDMA) is used for recreational purposes worldwide. The use of MDMA resulted in learning and memory dysfunction. Duloxetine, a serotonin/noradrenalin-reuptake inhibitor is also utilized to treat depression and anxiety. The current study aimed to evaluate the effects of duloxetine against MDMAchr('39')s effect on anxiety, cognition, and...
A significant proportion of patients with major depressive disorder are refractory to approved interventions. The first report of significant and rapid benefit of intravenous (IV) ketamine for treatment resistant depression (TRD) appeared in 2000. Since then, there have been multiple reports on the efficacy and tolerability of ketamine formulations for TRD, in particular for single-dose IV...
ABSTRACT Objectives Rigorous clinical trials suggest ketamine is safe and well-tolerated in patients with treatment-resistant depression (TRD). There is a paucity of data on the safety and tolerability of ketamine in community-based clinics treating patients with TRD. Methods Retrospective data was analyzed from 203 patients with TRD who received repeat-dose IV ketamine. Safety was...
Juvenile stress, like that caused by childhood maltreatment, is a significant risk factor for psychiatric disorders such as depression later in life. Recently, the antidepressant effect of ketamine, a noncompetitive N-methyl-d-aspartate receptor antagonist, has been widely investigated. However, little is known regarding its efficacy against depressive-like alterations caused by juvenile...

A study on a large sample of participants (N = 5512) across three countries, India, China, and the United States, suggested there are at least five cross-cultural phenotypic dimensions of personal spiritual capacity—spiritual reflection and commitment; contemplative practice; perception of...
