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 [...]

Cannabidiol Adverse Effects and Toxicity, Marilyn A. Huestis et al., 2019

Cannabidiol Adverse Effects and Toxicity Marilyn A. Huestis, Renata Solimini, Simona Pichini, Roberta Pacifici, Jeremy Carlier and Francesco Paolo Busardò Current Neuropharmacology, 2019, 17, 974-989 Doi : 10.2174/1570159XI7666190603171901 Abstract : Background : Currently, there is a great interest in the potential medical use of cannabidiol (CBD), a non-intoxicating cannabinoid. Productive pharmacological research on CBD occurred in the 1970s and intensified recently with many discoveries about the endocannabinoid system. Multiple preclinical and clinical studies led to FDA-approval of Epidiolex®, a purified CBD medicine formulated for oral administration for the treatment of infantile refractory epileptic syndromes, by the US Food and Drug Administration in 2018. The World [...]

Potential Pharmacokinetic Drug-Drug Interactions between Cannabinoids and Drugs Used for Chronic Pain, Marta Vázquez et al., 2020,

Potential Pharmacokinetic Drug-Drug Interactions between Cannabinoids and Drugs Used for Chronic Pain Marta Vázquez, Natalia Guevara, Cecilia Maldonado, Paulo Cáceres Guido, and Paula Schaiquevich Hindawi, BioMed Research International, 2020, Article ID 3902740, 9 pages Doi : 10.1155/2020/3902740 Choosing an appropriate treatment for chronic pain remains problematic, and despite the available medication for its treatment, still, many patients complain about pain and appeal to the use of cannabis derivatives for pain control. However, few data have been provided to clinicians about the pharmacokinetic drug-drug interactions of cannabinoids with other concomitant administered medications. Therefore, the aim of this brief review is to assess the interactions between [...]

Cannabinoids Promising for Improving Appetite, Behavior in Dementia, Pauline Anderson, Medscape Medical News, 2021

Cannabinoids Promising for Improving Appetite, Behavior in Dementia Pauline Anderson Medscape Medical News © March 19, 2021 For patients with dementia, cannabinoids may be a promising intervention for treating neuropsychiatric symptoms (NPS) and the refusing of food, new research suggests. Results of a systematic literature review showed that cannabinoids were associated with reduced agitation, longer sleep, and lower NPS. They were also linked to increased meal consumption and weight gain. Refusing food is a common problem for patients with dementia, often resulting in worsening sleep, agitation, and mood, study investigator Niraj Asthana, MD, a second-year resident in the Department of Psychiatry, University of California, San Diego, told [...]

Les interactions CBD / médicaments, Swiss Medical Cannabis, 2020

Les interactions CBD / médicaments Posté le 6 avril 2020 par Swiss Medical Cannabis   Depuis l’augmentation de sa demande, le cannabidiol (CBD) attire significativement l’attention sur son potentiel à soulager les symptômes de l’insomnie, de l’anxiété, de la douleur chronique et d’une foule d’autres problèmes de santé. Les recherches menées à ce jour démontrent progressivement que le CBD est d’une grande sécurité d’emploi même à forte dose et peu d’effets secondaires, somme toute mineurs. Toutefois, il existe une mise en garde : le CBD peut interagir avec certains médicaments. L’interrogation porte ainsi sur la façon dont le corps métabolise certaines substances. Avant de [...]
