“Background: Patients with Inflammatory bowel disease (IBD) often seek alternative therapies for symptom management. This study investigates the perceptions, consumption patterns, and reported outcomes of cannabis and cannabidiol (CBD) oil use among IBD patients and controls.

Methods: A 37-question survey was administered to 139 participants (IBD patients, n = 93; control/non-IBD participants, n = 33) to assess usage frequency and beliefs regarding cannabis and CBD oil as treatment for IBD. The survey also evaluated the impact of these substances on IBD symptoms, quality of life, and opioid use.

Results: Cannabis consumption was higher in IBD patients (57, 53.8%) than controls (15, 45.5%) with both groups strongly supporting medical cannabis use (IBD; 92, 86.8% vs. controls; 29, 84.9%). Most IBD patients believed cannabis (67, 63.2%), CBD oil (60, 56.6%), corticosteroids (77, 73.3%), and biologics/immunosuppressants (85, 81.0%) had a somewhat-extremely beneficial effect in relieving IBD symptoms. Over 50% of IBD cannabis users reported relief from abdominal pain, other pain, stress, anxiety, depression, and nausea/vomiting, with Crohn’s disease patients experiencing significantly more relief than ulcerative colitis patients for certain symptoms (p < 0.05). Notably, 19.4% of IBD patients reported decreased opioid use, and 14.5% reported induced remission with cannabis or CBD oil.

Conclusions: Consumption of cannabis and CBD oil was perceived as beneficial for relieving IBD, with many reporting significant symptom relief from using these substances. The strong support of cannabis and CBD oil as medical treatments and therapeutic effects highlights the potential for cannabis and CBD oil as treatments in IBD.”

“Recent preclinical studies have suggested that cannabinoids, including CBD and THC, may reduce gastrointestinal inflammation and modulate intestinal motility. The presence of cannabinoid receptors in the gut, along with the anti-inflammatory effects of some cannabinoids, has led researchers to explore the potential for therapeutic applications of cannabis in the treatment of IBD.”

“Animal studies of the chemistry and physiology of cannabinoids have shown potential anti-inflammatory, antidiarrheal, and nociceptive-limiting effects, paralleling the growing interest in cannabis as a treatment option for IBD.

Human studies have also indicated that there may be a benefit in controlling IBD symptoms and improving quality of life. Additionally, anecdotal reports and observational studies have highlighted potential benefits in reducing disease activity and managing symptoms like abdominal pain, cramping, joint pain, and diarrhea.”

“Historically, the multiple uses of cannabis as a medicine, food, and for recreational purposes as a psychoactive drug span several centuries.

The various components of the plant (i.e., seeds, roots, leaves and flowers) have been utilized to alleviate symptoms of inflammation and pain (e.g., osteoarthritis, rheumatoid arthritis), mood disorders such as anxiety, and intestinal problems such as nausea, vomiting, abdominal pain and diarrhea.

It has been established that the intestinal microbiota progresses neurological, endocrine, and immunological network effects through the gut-microbiota-brain axis, serving as a bilateral communication pathway between the central and enteric nervous systems.

An expanding body of clinical evidence emphasizes that the endocannabinoid system has a fundamental connection in regulating immune responses. This is exemplified by its pivotal role in intestinal metabolic and immunity equilibrium and intestinal barrier integrity.

This neuromodulator system responds to internal and external environmental signals while also serving as a homeostatic effector system, participating in a reciprocal association with the intestinal microbiota.

We advance an exogenous cannabinoid-intestinal microbiota-endocannabinoid system axis potentiated by the intestinal microbiome and medicinal cannabinoids supporting the mechanism of action of the endocannabinoid system. An integrative medicine model of patient care is advanced that may provide patients with beneficial health outcomes when prescribed medicinal cannabis.”

“Furthermore, other modes of delivery of medicinal cannabis, such as oro-buccal, sublingual and inhaled/smoked alternatives, provide cannabinoids that have rapid access to the systemic circulation, bypassing the intestinal tract.”

The Endocannabinoid System: A Potential Target for the Treatment of Various Diseases

Posted on by

ijms-logo“The Endocannabinoid System (ECS) is primarily responsible for maintaining homeostasis, a balance in internal environment (temperature, mood, and immune system) and energy input and output in living, biological systems.

In addition to regulating physiological processes, the ECS directly influences anxiety, feeding behaviour/appetite, emotional behaviour, depression, nervous functions, neurogenesis, neuroprotection, reward, cognition, learning, memory, pain sensation, fertility, pregnancy, and pre-and post-natal development.

The ECS is also involved in several pathophysiological diseases such as cancer, cardiovascular diseases, and neurodegenerative diseases. In recent years, genetic and pharmacological manipulation of the ECS has gained significant interest in medicine, research, and drug discovery and development.

The distribution of the components of the ECS system throughout the body, and the physiological/pathophysiological role of the ECS-signalling pathways in many diseases, all offer promising opportunities for the development of novel cannabinergic, cannabimimetic, and cannabinoid-based therapeutic drugs that genetically or pharmacologically modulate the ECS via inhibition of metabolic pathways and/or agonism or antagonism of the receptors of the ECS. This modulation results in the differential expression/activity of the components of the ECS that may be beneficial in the treatment of a number of diseases.

This manuscript in-depth review will investigate the potential of the ECS in the treatment of various diseases, and to put forth the suggestion that many of these secondary metabolites of Cannabis sativa L. (hereafter referred to as “C. sativa L.” or “medical cannabis”), may also have potential as lead compounds in the development of cannabinoid-based pharmaceuticals for a variety of diseases.”

Gastrointestinal Adverse Events of Cannabinoid 1 Receptor Inverse Agonists suggest their Potential Use in Irritable Bowel Syndrome with Constipation: A Systematic Review and Meta-Analysis.

Posted on by

 Image result for J Gastrointestin Liver Dis“Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal (GI) disorders characterized by pain and impaired bowel movements. Currently available drugs show limited efficacy.

Cannabinoid 1 receptor (CB1) inverse agonists (CB1-RAN) cause diarrhea and may be candidates for the treatment of constipation-predominant IBS (IBS-C). We evaluated the effects of CB1-RAN in clinical trials for their potential use in IBS-C.

METHODS:

Database search identified all clinical trials published up to May 2018 that reported rimonabant and taranabant treatment for at least one month and detailed the GI adverse events (AEs). Categorical outcomes (subgroups of AEs) were analyzed using the odds ratio (OR).

RESULTS:

Eighteen trials met the inclusion criteria. Rimonabant 20 mg produced significantly more overall AEs (OR=1.35, CI: 1.19-1.52, p<0.0001), psychiatric events (OR=1.79, CI: 1.46-2.21, p<0.001) and GI AEs (OR=2.05, CI: 1.65-2.55, p<0.001) compared to placebo. Taranabant at doses ranging from 0.5 to 8 mg produced significantly more overall AEs (OR=1.36, CI: 1.13-1.64, p<0.002), psychiatric AEs (1.82, CI: 1.54-2.16, p<0.001) and GI AEs (OR=1.75, CI: 1.29-2.37, p<0.001) compared to placebo.

CONCLUSIONS:

The approach to target CB1 in the gut for the treatment of IBS-C or chronic constipation seems a promising therapeutic option. Prospective clinical trials on the possible targeting of CB1 and the endocannabinoid system are warranted.”

“Through the years, the endocannabinoid system has been recognized in the homeostatic mechanisms of the gut, as well as in the physiological control of intestinal motility and secretion. Accordingly, cannabinoids may be a promising therapy against several gastrointestinal conditions, such as abdominal pain and motility-related disorders. After three months of therapy, oral nabilone improved the health of nearly all patients, with visible improvements in reducing diarrheal symptoms and weight gain. These findings encourage the study of cannabinoids acting on CB1 receptors in chronic gastrointestinal disorders, especially in refractory chronic diarrhea, offering a chance for a substantial improvement in the quality of life of selected patients, with a reasonable safety profile.” https://bmcgastroenterol.biomedcentral.com/articles/10.1186/s12876-019-1024-y

The novel peripherally active cannabinoid type 1 and serotonin type 3 receptor agonist AM9405 inhibits gastrointestinal motility and reduces abdominal pain in mouse models mimicking irritable bowel syndrome.

“The endocannabinoid system (ECS) plays a crucial role in numerous physiological processes in the central and peripheral nervous systems. In the gastrointestinal (GI) tract, selective cannabinoid (CB) receptor agonists exert potent inhibitory actions on motility and pain signalling. In the present study, we used mouse models of diarrhea, hypermotility, and abdominal pain to examine whether a novel synthetic CB1 receptor agonist AM9405 [(2-(2,6-dihydroxy-4-(2-methyloctan-2-yl)phenyl)-1,3-dimethyl-1H-benzo[d]imidazol-3-ium bromide); also known as GAT379] exhibits effects of potential therapeutic relevance. AM9405 significantly slowed mouse intestinal motility in physiological conditions. Moreover, AM9405 reversed hypermotility and reduced pain in mouse models mimicking symptoms of functional GI disorders, such as stress-induced diarrhoea and writhing test. Interestingly, some of the effects of AM9405 were blocked by a 5-HT3 antagonist suggesting interaction with 5-HT3 receptors. In our study we show that combining CB1 agonism with 5-HT3 agonism may alter physiological functions and experimental pathophysiologies in a manner that make such compounds promising drugs for the future treatment of functional GI disorders.” https://www.ncbi.nlm.nih.gov/pubmed/30121173 https://www.sciencedirect.com/science/article/pii/S0014299918304734?via%3Dihub]]>

Cannabinoid pharmacology and therapy in gut disorders.

Posted on by

Biochemical Pharmacology “Cannabis sp and their products (marijuana, hashish…), in addition to their recreational, industrial and other uses, have a long history for their use as a remedy for symptoms related with gastrointestinal diseases. After many reports suggesting these beneficial effects, it was not surprising to discover that the gastrointestinal tract expresses endogenous cannabinoids, their receptors, and enzymes for their synthesis and degradation, comprising the so-called endocannabinoid system. This system participates in the control of tissue homeostasis and important intestinal functions like motor and sensory activity, nausea, emesis, the maintenance of the epithelial barrier integrity, and the correct cellular microenvironment. Thus, different cannabinoid-related pharmacological agents may be useful to treat the main digestive pathologies. To name a few examples, in irritable bowel syndrome they may normalize dysmotility and reduce pain, in inflammatory bowel disease they may decrease inflammation, and in colorectal cancer, apart from alleviating some symptoms, they may play a role in the regulation of the cell niche. This review summarizes the main recent findings on the role of cannabinoid receptors, their synthetic or natural ligands and their metabolizing enzymes in normal gastrointestinal function and in disorders including irritable bowel syndrome, inflammatory bowel disease, colon cancer and gastrointestinal chemotherapy-induced adverse effects (nausea/vomiting, constipation, diarrhea).”
