Cannabinoid-based Medications for Pain Raymond M. St. Marie, Raphael J. Leo, 2021

Cannabinoid-based Medications for Pain Raymond M. St. Marie, MD; Raphael J. Leo, MA, MD Current Psychiatry, 2021, 20(5), 21-33. Abstract and Introduction Introduction Against the backdrop of an increasing opioid use epidemic and a marked acceleration of prescription opioid–related deaths,[1,2] there has been an impetus to explore the usefulness of alternative and co-analgesic agents to assist patients with chronic pain. Preclinical studies employing animal-based models of human pain syndromes have demonstrated that cannabis and chemicals derived from cannabis extracts may mitigate several pain conditions.[3] Because there are significant comorbidities between psychiatric disorders and chronic pain, psychiatrists are likely to care for patients with chronic pain. As [...]

Neuroprotective Effect of Cannabidiol Against Hydrogen Peroxide in Hippocampal Neuron Culture, Jungnam Kim et al., 2021

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, 2021, Volume 6, Number 1, 40-48. 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 : [...]

Reducing Effect of Cannabidiol on Alcohol Self-Administration in Sardinian Alcohol-Preferring Rats, Paola Maccioni et al., 2021

Reducing Effect of Cannabidiol on Alcohol Self-Administration in Sardinian Alcohol-Preferring Rats Paola Maccioni, Jessica Bratzu, Mauro A.M. Carai, Giancarlo Colombo, and Gian Luigi Gessa Cannabis and Cannabinoid Research, 2021, Doi : 10.1089/can.2020.0132   Abstract Introduction : Cannabidiol (CBD) is a major cannabinoid extracted from Cannabis sativa with no abuse potential. Data from recent rodent studies suggest that amelioration of alcohol-motivated behaviors may be one of the numerous pharmacological effects of CBD. This study was designed to contribute to this research, assessing the effect of CBD on operant oral alcohol self-administration in selectively bred Sardinian alcohol preferring (sP) rats, a validated animal model of excessive alcohol consumption.

New Insights on Hemp Oil Enriched in Cannabidiol: Decarboxylation, Antioxidant Properties and In Vitro Anticancer Effect, Anca Roxana Petrovici et al., 2021

New Insights on Hemp Oil Enriched in Cannabidiol: Decarboxylation, Antioxidant Properties and In Vitro Anticancer Effect Anca Roxana Petrovici, Natalia Simionescu, Andreea Isabela Sandu, Vasile Paraschiv, Mihaela Silion and Mariana Pinteala Antioxidants, 2021, 10, 738. doi : 10.3390/antiox10050738   Abstract : This study aimed to obtain and characterize extracted hemp oil enriched in cannabidiol (CBD) by decarboxylation of cannabidiolic acid (CBDA) and to give new insights into its antioxidant and anticancer effects. Optimization of CBDA decarboxylation in hemp oil was performed, and CBD and CBDA contents and purities were determined by flash chromatography, 1H- and 13C-NMR. The antioxidant properties of CBD-enriched oil were investigated by Fe2+ [...]

Cannabidiol induces rapid-acting antidepressant-like effects and enhances cortical 5-HT/glutamate neurotransmission : role of 5-HT1A receptors, Raquel Linge et al., 2016

Cannabidiol induces rapid-acting antidepressant-like effects and enhances cortical 5-HT/glutamate neurotransmission: role of 5-HT1A receptors Raquel Linge, Laura Jimenez-Sanchez, Leticia Campa, Fuencisla Pilar-Cuellar, Rebeca, Vidal, Angel Pazos, Albert Adell, Alvaro Diaz Neuropharmacology, 2016, 103, 16-26. doi : 10.1016/j.neuropharm.2015.12.017 Abstract Cannabidiol (CBD), the main non-psychotomimetic component of marihuana, exhibits anxiolytic-like properties in many behavioural tests, although its potential for treating major depression has been poorly explored. Moreover, the mechanism of action of CBD remains unclear. Herein, we have evaluated the effects of CBD following acute and chronic administration in the olfactory bulbectomy mouse model of depression (OBX), and investigated the underlying mechanism. For this purpose, we [...]
