Cannabis and cannabinoid drug development: evaluating botanical versus single molecule approaches, Marcel O. Bonn-Miller et al., 2018

Cannabis and cannabinoid drug development: evaluating botanical versus single molecule approaches Marcel O. Bonn-Miller, Mahmoud A. ElSohly, Mallory J. E. Loflin, Suman Chandra and Ryan Vandrey International Review of Psychiatry, 2018, VOL. 30, NO. 3, 277–284 Doi : 10.1080/09540261.2018.1474730   ABSTRACT Accumulating evidence suggests that the endocannabinoid system is a promising target for the treatment of a variety of health conditions. Two paths of cannabinoid drug development have emerged. One approach is focused on developing medications that are directly derived from the cannabis plant. The other utilizes a single molecule approach whereby individual phytocannabinoids or novel cannabinoids with therapeutic potential are identified and synthesized for pharmaceutical [...]

Neuroprotective Effect of Cannabidiol Against Hydrogen Peroxide in Hippocampal Neuron Culture, Jungnam Kim et al. 2020

Neuroprotective Effect of Cannabidiol Against Hydrogen Peroxide in Hippocampal Neuron Culture Jungnam Kim, Ji Yu Choi, Jeongyeon Seo, and Insung S. Choi Cannabis and Cannabinoid Research, 2020,Volume X, Number X, Doi : 10.1089/can.2019.0102   Abstract Introduction: Reports on the neurotoxic and neuroprotective effects of cannabidiol (CBD) have not been in complete accord, showing different and somewhat contradictory results depending upon the brain cell types and experimental conditions employed. This work systematically examines the neuroprotective capability of CBD against oxidative stress (i.e., hydrogen peroxide [H2O2]) as well as its toxicity profile in the in vitro culture platform of primary hippocampal neurons. Materials and Methods: The low cell-density (100 neurons [...]

Nonlinear Disposition and Metabolic Interactions of Cannabidiol Through CYP3A Inhibition In Vivo in Rats, Michiru Nagao et al., 2020

Nonlinear Disposition and Metabolic Interactions of Cannabidiol Through CYP3A Inhibition In Vivo in Rats Michiru Nagao, Yukako Nakano, Masataka Tajima, Erika Sugiyama, Vilasinee Hirunpanich Sato, Makoto Inada, and Hitoshi Sato Cannabis and Cannabinoid Research, 2020, Volume X, Number X, 1-8. DOI: 10.1089/can.2019.0098   Abstract Introduction : Cannabidiol (CBD) is known to affect the pharmacokinetics of other drugs through metabolic inhibition of CYP2C19 and CYP3A4. However, there is a lack of in vivo evidence for such drug interactions. Therefore, we investigated the saturability of CBD metabolism and CBD-drug interactions through inhibition of CYP3A in vivo. Materials and Methods : A nanoemulsion formulation of CBD (CBD-NE) was orally administered to [...]

Therapeutic Use of LSD in Psychiatry : A Systematic Review of Randomized- Controlled Clinical Trials, Juan Jose Fuentes et al., 2020

Therapeutic Use of LSD in Psychiatry : A Systematic Review of Randomized-Controlled Clinical Trials Juan José Fuentes, Francina Fonseca, Matilde Elices, Magí Farré and Marta Torrens Frontiers in Psychiatry, 2020, Vol 10, Article 943. doi : 10.3389/fpsyt.2019.00943   Lysergic acid diethylamide (LSD) was studied from the 1950s to the 1970s to evaluate behavioral and personality changes, as well as remission of psychiatric symptoms in various disorders. LSD was used in the treatment of anxiety, depression, psychosomatic diseases and addiction. However, most of the studies were not performed under contemporary standards, and it has taken several decades for a resurgence of interest in LSD research and [...]

Acute and chronic effects of cannabinoids on effort-related decision-making and reward learning: an evaluation of the cannabis ‘amotivational’ hypotheses, Will Lawn et al., 2016

Acute and chronic effects of cannabinoids on effort-related decision-making and reward learning: an evaluation of the cannabis ‘amotivational’ hypotheses Will Lawn, Tom P. Freeman, Rebecca A. Pope, Alyssa Joye, Lisa Harvey, Chandni Hindocha, Claire Mokrysz, Abigail Moss, Matthew B. Wall, Michael A.P. Bloomfield, Ravi K. Das, Celia J.A. Morgan, David J. Nutt, H. Valerie Curran Psychopharmacology, 2016, 233, 3537–3552 Doi : 10.1007/s00213-016-4383-x   Abstract Rationale : Anecdotally, both acute and chronic cannabis use have been associated with apathy, amotivation, and other reward processing deficits. To date, empirical support for these effects is limited, and no previous studies have assessed both acute effects of Δ-9-tetrahydrocannabinol (THC) and [...]

Doi : 10.3238/arztebl.2017.0627   SUMMARY Background : There are conflicting interpretations of the evidence regarding the efficacy, tolerability, and safety of cannabinoids in pain management and palliative medicine. Methods : We conducted a systematic review (SR) of systematic reviews of randomized controlled trials (RCT) and prospective long-term observational studies of the use of cannabinoids in pain management and palliative medicine. Pertinent publications from January 2009 to January 2017 were retrieved by a selective search in the Cochrane [...]

Modern Clinical Research on LSD, Matthias E Liechti, 2017

Modern Clinical Research on LSD Matthias E Liechti Neuropsychopharmacology, 2017, 42, 2114–2127. doi : 10.1038/npp.2017.86   All modern clinical studies using the classic hallucinogen lysergic acid diethylamide (LSD) in healthy subjects or patients in the last 25 years are reviewed herein. There were five recent studies in healthy participants and one in patients. In a controlled setting, LSD acutely induced bliss, audiovisual synesthesia, altered meaning of perceptions, derealization, depersonalization, and mystical experiences. These subjective effects of LSD were mediated by the 5-HT2A receptor. LSD increased feelings of closeness to others, openness, trust, and suggestibility. LSD impaired the recognition of sad and fearful faces, reduced left [...]
