A Phase 2, Double-Blind, Placebo-Controlled Trial to Investigate Potential Drug-Drug Interactions Between Cannabidiol and Clobazam, Kevan E. Van Landingham et al., 2020

A Phase 2, Double-Blind, Placebo-Controlled Trial to Investigate Potential Drug-Drug Interactions Between Cannabidiol and Clobazam Kevan E. Van Landingham, MD, PhD1, Julie Crockett, PhD2, Lesley Taylor, PhD2*, and Gilmour Morrison, HND2 The Journal of Clinical Pharmacology, 2020, 0, (0), 1–10 Doi : 10.1002/jcph.1634   Abstract We investigated the effects of cannabidiol (CBD; 21-day maintenance dose) on the pharmacokinetics (PK) of clobazam (CLB) and monitored the safety of CBD (or placebo) plus CLB in 20 patients with uncontrolled epilepsy on stable doses of CLB. Blood samples collected until 24 hours postdose were evaluated by liquid chromatography tandem mass spectrometry. PK parameters of CLB and major metabolite N-desmethylclobazam (N-CLB), [...]

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 [...]

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.

Cannabinoids, Phenolics, Terpenes and Alkaloids of Cannabis Mohamed M. Radwan, Suman Chandra, Shahbaz Gul and Mahmoud A. ElSohly Molecules, 2021, 26, 2774. Doi : 10.3390/molecules26092774   Abstract : Cannabis sativa is one of the oldest medicinal plants in the world. It was introduced into western medicine during the early 19th century. It contains a complex mixture of secondary metabolites, including cannabinoids and non-cannabinoid-type constituents. More than 500 compounds have been reported from C. sativa, of which 125 cannabinoids have been isolated and/or identified as cannabinoids. Cannabinoids are C21 terpeno phenolic compounds specific to Cannabis. The non-cannabinoid constituents include: non-cannabinoid phenols, flavonoids, terpenes, alkaloids and others.

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+ [...]
