Efficacy and Safety of Ketamine/Esketamine in Bipolar Depression in a Clinical Setting.

The Journal of Clinical Psychiatry October 2, 2024 Mia C Santucci, Mina Ansari, Sina Nikayin et al. 12 citations

Background: Bipolar disorder represents a significant source of morbidity and elevated mortality risk. Ketamine has emerged as a powerful antidepressant; however, there have been few trials of ketamine in bipolar depression and no trials with esketamine in bipolar depression, and few data exist from real-world settings. Here, we report outcomes from a cohort of patients with bipolar depression...

Role of Psychedelics in Treatment-Resistant Depression.

The Psychiatric clinics of North America June 1, 2023 Shubham Kamal, Manish Kumar Jha, Rajiv Radhakrishnan 32 citations

There is increasing interest in exploring the therapeutic potential of psychedelics in treatment-resistant depression (TRD). Classic psychedelics (such as psilocybin, LSD, ayahuasca/DMT), and atypical psychedelics (such as ketamine) have been studied in TRD. The evidence for the classic psychedelics TRD is limited at the present time; early studies however show promising results. There is also...

Therapeutic Potential of Psychedelics in Treatment of Psychiatric Disorders, Part 2

The Journal of Clinical Psychiatry February 23, 2021 Avinash Hosanagar, Joseph Cusimano, Rajiv Radhakrishnan 1 citation

P sychedelics have recently gained attention as compounds with therapeutic potential in the treatment of psychiatric disorders.The US Food and Drug Administration (FDA) has granted Breakthrough Therapy Designations for (±)-3,4-methylenedioxymethamphetamine (MDMA) as an adjunct to psychotherapy in severe posttraumatic stress disorder (PTSD) (in 2017) and for the adjunctive use of psilocybin with...

Tetrahydrocannabinol (THC) impairs encoding but not retrieval of verbal information.

Progress in neuro-psychopharmacology & biological psychiatry October 3, 2017 Mohini Ranganathan, Rajiv Radhakrishnan, Peter H Addy et al.

Cannabis and agonists of the brain cannabinoid receptor (CB1R) produce acute memory impairments in humans. However, the extent to which cannabinoids impair the component processes of encoding and retrieval has not been established in humans. The objective of this analysis was to determine whether the administration of Δ9-Tetrahydrocannabinol (THC), the principal psychoactive constituent of...

Human Laboratory Studies on Cannabinoids and Psychosis.

Biological Psychiatry April 1, 2016 Mohamed Sherif, Rajiv Radhakrishnan, Deepak Cyril D'Souza et al. 127 citations

Some of the most compelling evidence supporting an association between cannabinoid agonists and psychosis comes from controlled laboratory studies in humans. Randomized, double-blind, placebo-controlled, crossover laboratory studies demonstrate that cannabinoid agonists, including phytocannabinoids and synthetic cannabinoids, produce a wide range of positive, negative, and cognitive symptoms...

Effects of Δ9-tetrahydrocannabinol in individuals with a familial vulnerability to alcoholism.

Psychopharmacology June 2014 Mohini Ranganathan, R Andrew Sewell, Michelle Carbuto et al.

A family history (FH) of alcoholism accounts for approximately 50% of the risk of developing alcohol problems. Several lines of preclinical evidence suggest that brain cannabinoid receptor (CB1R) function may mediate the effects of alcohol and risk for developing alcoholism including the observations that reduced CB1R function decreases alcohol-related behaviors and enhanced CB1R function...

Acute Effects of THC on Time Perception in Frequent and Infrequent Cannabis Users

Psychopharmacology November 24, 2012 R. A. Sewell, Ashley Schnakenberg, Jacqueline Elander et al.

Cannabinoids have been shown to alter time perception, but existing literature has several limitations. Few studies have included both time estimation and production tasks, few control for subvocal counting, most had small sample sizes, some did not record subjects’ cannabis use, many tested only one dose, and used either oral or inhaled administration of Δ9-tetrahydrocannabinol (THC), leading...
