Objective We assessed the efficacy, safety, and tolerability of cannabidivarin (CBDV) as add-on therapy in adults with inadequately controlled focal seizures. Materials and Methods One hundred and sixty-two participants (CBDV n=81; placebo n=81) were enrolled. After a 4-week baseline, participants titrated from 400 to 800 mg CBDV twice daily (b.i.d.) (or placebo) over 2 weeks, followed by 6 weeks stable dosing (at 800 mg b.i.d.) and a 12-day taper period. The primary endpoint was the change from baseline in focal seizure frequency during the 8-week treatment period. Secondary endpoints included additional efficacy measures relating to seizures, physician- and participant-reported outcomes, change in the use of rescue medication, cognitive assessments, and safety. Results Median baseline focal seizure frequencies were 17-18 per 28 days in both groups, and similar reductions in frequency were observed in the CBDV (40.5%) and placebo (37.7%) groups during the treatment period (treatment ratio [% reduction] CBDV/n with CBDV represents an appropriate pharmacological response in this population with focal seizures. The placebo response was, however, high, which may reflect the participants' expectations of CBDV, and a treatment difference from placebo was not observed. CBDV was generally well tolerated. Clinical Trial Registration number NCT02365610.Background Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of mortality in the United States. Due to the ongoing legalization of cannabis, its acceptance, availability, and use in the in-patient population are on the rise. In this retrospective study, we investigated the association of cannabis use with important outcomes in COPD hospitalizations. Methods The National Inpatient Sample (NIS) data were analyzed from 2005 to 2014. The primary outcome of interest was the trends and outcomes of cannabis use among COPD hospitalizations, including in-hospital mortality, pneumonia, sepsis, and respiratory failure. Results We identified 6,073,862 hospitalizations, 18 years of age or older, with COPD using hospital discharge codes. Of these, 6,049,316 (99.6%) were without cannabis use, and 24,546 (0.4%) were admitted with cannabis use. The majority of COPD hospitalizations with cannabis use were aged 50-64 (60%). Cannabis use was associated with lower odds of in-hospital mortality (odds ratio [OR] 0.624 [95% confidence interval (CI) 0.407-0.958]; p=0.0309) and pneumonia (OR 0.882 [95% CI 0.806-0.964]; p=0.0059) among COPD hospitalizations. Cannabis use also had lower odds of sepsis (OR 0.749 [95% CI 0.523-1.071]; p=0.1127) and acute respiratory failure (OR 0.995 [95% CI 0.877-1.13]; p=0.9411), but it was not statistically significant. Conclusions Among hospitalized patients with a diagnosis of COPD, cannabis users had statistically significant lower odds of in-hospital mortality and pneumonia compared to noncannabis users. The association between cannabis use and these favorable outcomes deserves further study to understand the interaction between cannabis use and COPD.Decades of research have discovered a broad variety of interesting in vitro activities resulting from cannabinoid exposure. Recent investigations of cannabidiol, however, present a potential explanation for these findings, which relies on the nonspecific effects of colloidal dispersions as opposed to those of specific drug interactions with macromolecular targets. This perspective raises the question of how false-positive assay results arising from such colloidal interference may permeate the field of cannabinoid pharmacology. It further suggests a direction for future research with the intent of identifying true pharmacological interactions that might be more efficiently developed into therapeutic targets.Background Irritable bowel syndrome (IBS) is one of the most common gastrointestinal disorders. Its pathophysiology is diverse and variable, involving disturbed gut-brain interactions, altered motility and secretion, visceral hypersensitivity, increased intestinal permeability, immune activation, and changes in gut microbiota. Complaints experienced by patients suffering from IBS and its co-morbidities strongly impair quality of life (QoL), and available treatments are often unsatisfactory. Anecdotal reports and preclinical data suggest that the endocannabinoid system and functionally related mechanisms could offer treatment targets. Cannabidiol (CBD) is a candidate agent of interest with a broad molecular target profile and the absence of psychoactive properties. Materials and Methods In 32 female IBS patients, we explored the effect of a chewing gum formulation containing 50 mg CBD on abdominal pain and perceived well-being in a randomized, double-blinded, placebo-controlled cross-over trial. Chewing gums wmore personalized, for example by applying an N-of-1 (rotating) design with individualized dose titration.Introduction Low voltage-activated T-type calcium channels (T-type ICa), CaV3.1, CaV3.2, and CaV3.3, are opened by small depolarizations from the resting membrane potential in many cells and have been associated with neurological disorders, including absence epilepsy and pain. Δ9-tetrahydrocannabinol (THC) is the principal psychoactive compound in Cannabis and also directly modulates T-type ICa; however, there is no information about functional activity of most phytocannabinoids on T-type calcium channels, including Δ9-tetrahydrocannabinolic acid (THCA), the natural nonpsychoactive precursor of THC. The aim of this work was to characterize THCA effects on T-type calcium channels. Materials and Methods We used HEK293 Flp-In-TREx cells stably expressing CaV3.1, 3.2, or 3.3. Whole-cell patch clamp recordings were made to investigate cannabinoid modulation of ICa. Results THCA and THC inhibited the peak current amplitude CaV3.1 with pEC50s of 6.0±0.7 and 5.6±0.4, respectively. THC (1 μM) or THC produced a significant negative shift in half activation and inactivation of CaV3.1, and both drugs prolonged CaV3.1 deactivation kinetics. THCA (10 μM) inhibited CaV3.2 by 53%±4%, and both THCA and THC produced a substantial negative shift in the voltage for half inactivation and modest negative shift in half activation of CaV3.2. THC prolonged the deactivation time of CaV3.2, while THCA did not. THCA inhibited the peak current of CaV3.3 by 43%±2% (10 μM) but did not notably affect CaV3.3 channel activation or inactivation; however, THC caused significant hyperpolarizing shift in CaV3.3 steady-state inactivation. Discussion THCA modulated T-type ICa currents in vitro, with significant modulation of kinetics and voltage dependence at low μM concentrations. This study suggests that THCA may have potential for therapeutic use in pain and epilepsy through T-type calcium channel modulation without the unwanted psychoactive effects associated with THC.Introduction As more states allow for medical and nonregistered adult cannabis (i.e., marijuana) use, ensuring proper utilization should be a priority. Standardized labeling for foods and pharmaceutical drugs promotes consumer safety. find more This study investigated cannabis product labeling requirements in the United States. Materials and Methods Researchers compiled the requirements for cannabis product labeling across 31 U.S. states with medical cannabis programs from state regulatory publications. Results Information requirements ranged considerably by U.S. state. All states required delta-9-tetrahydrocannabinol content and manufacturer contact information, >80% of states required the batch number, health risks, production tracking, a cannabis symbol, cannabidiol content, children disclaimer, and an impairment disclaimer. There appeared to be a random pattern in requirements for other specific items. The relationships between the extent of cannabis product labeling requirements and the number of years that a state had a medical cannabis program or whether states allowed nonregistered adult use cannabis were not significant, although there was a trend for nonregistered adult use states to require more recommended label attributes. Conclusion A comprehensive framework for cannabis use is needed to protect the public, maximize benefits, and minimize harms and risks. Standardization of cannabis product labeling requirements would benefit consumers and promote safer and more effective usage of cannabis products.Background Alterations of astrocyte function play a crucial role in neuroinflammatory diseases due to either the loss of their neuroprotective role or the gain of their toxic inflammatory properties. Accumulating evidence highlights that cannabinoids and cannabinoid receptor agonists, such as WIN55,212-2 (WIN), reduce inflammation in cellular and animal models. Thus, the endocannabinoid system has become an attractive target to attenuate chronic inflammation in neurodegenerative diseases. However, the mechanism of action of WIN in astrocytes remains poorly understood. Objective We studied the immunosuppressive property of WIN by examining gene expression patterns that were modulated by WIN in reactive astrocytes. Materials and Methods Transcriptomic analysis by RNA-seq was carried out using primary human astrocyte cultures stimulated by the proinflammatory cytokine interleukin 1 beta (IL1β) in the presence or absence of WIN. Real-time quantitative polymerase chain reaction analysis was conducted on selected tffects of WIN. These results provide mechanistic insights into the anti-inflammatory activity of WIN and highlight that astrocytes are a potential therapeutic target to ameliorate neuroinflammation in the brain.In April 2020, after decades of discussions and controversy, the Lebanese parliament voted a law legalizing the cultivation, production, and sale of cannabis for medicinal purposes. Although the law leaves several unanswered questions and awaits implementation, the symbolic nature of this step in recognizing a positive role of cannabis in the local economy is significant on a regional level. The Arab world has traditionally been conservative when it comes to all drugs-related policies. Cannabis is largely demonized with heavy sentences served to anyone suspected of using selling, let alone planting cannabis. Despite a few countries considered producers and consumers of substances, governing authorities have remained immune to the liberalization trend encountered in western countries. The social experiment taking place in Lebanon is fraught with risks, given the unstable political situation and chronic economic challenges. The reactions to the law have been mixed with several scientific bodies such as the Lebanese Psychiatric Society criticizing the absence of proper consultation of stakeholders. The absence of consistency in enforcing established drugs policies or seriously debating the decriminalization of cannabis use raises concerns over the establishment of a two-tier approach toward drugs, driven solely by economic imperatives.Introduction Cannabis is commonly used for its medicinal and therapeutic benefits and is also widely used as a recreational drug. Cannabis use has been increasing in Canada, including among Canadian women of reproductive age. Post-legalization, further increases in cannabis use are expected due to increased availability and lowered perceptions of harm. Although cannabinoids are well known for their effects on the central and peripheral nervous systems, endocannabinoid receptors have also been characterized throughout the female reproductive tract. Cannabinoids may affect many aspects of female reproductive health, including fertility, pregnancy outcomes with neonatal implications, and menopause. Purpose To provide a comprehensive review of trends in cannabis use among women and review the impact of cannabis across the female reproductive lifespan. Methods We searched PubMed and Cochrane Library databases using keywords and MeSH terms. Included studies reported the potential impact of cannabinoids on female fertility, pregnancy, transmission to breast milk, neonatal outcomes, and menopause.
