“Sativex(®) (GW Pharmaceuticals PLC, Porton Down, UK; Laboratorios Almirall, SA, Barcelona, Spain), a cannabinoid oromucosal spray containing a 1:1 ratio of 9-δ-tetrahydrocannabinol and cannabidiol, has been licensed in Germany since July 2011 as add-on therapy for moderate-to-severe multiple sclerosis (MS) treatment-resistant spasticity symptoms.

The ‘MOVE 2′ study evaluated clinical outcomes, treatment satisfaction, quality of life (QoL) and provision of care in MS patients with spasticity receiving Sativex in everyday clinical practice. Data from 300 patients were collected from 42 specialized MS centers across Germany and were available for this analysis. Assessments, including the MS spasticity 0-10 numerical rating scale, modified Ashworth scale, patients’ and physicians’ clinical impressions, and QoL scales were rated at baseline and at 1 and 3 months after starting treatment with Sativex.

 Sativex provided relief of MS-related spasticity in the majority of patients who were previously resistant to treatment. In addition, clear improvements were noted in MS spasticity-associated symptoms (e.g., sleep quality, bladder function and mobility), activities of daily living and QoL. Sativex was generally well tolerated. The majority of patients (84%) reported no adverse events, and there was only a limited risk of serious adverse reactions.

Furthermore, based on data from Sativex clinical trials, a Markov model-based analysis has shown that Sativex is a cost-effective treatment option for patients with MS spasticity in Germany.”

“Spasticity is a disabling complication of multiple sclerosis. Some commonly used oral medications include baclofen, tizanidine, anticonvulsants and benzodiazepines, but their benefits are modest.

Sativex(®) (GW Pharmaceuticals PLC, Porton Down, UK; Laboratorios Almirall, SA, Barcelona, Spain) is a unique cannabinoid-based medicine with two main active ingredients; 9-δ-tetrahydrocannabinol, which acts mainly on cannabinoid 1 receptors in the CNS and plays a key role in the modulation of spasticity and spasms, and cannabidiol, which has different properties, including minimization of the psychoactivity associated with 9-δ-tetrahydrocannabinol. Sativex is indicated for symptomatic improvement in adult patients with moderate-to-severe multiple sclerosis-related spasticity who have not responded adequately to other first- or second-line antispasticity medications, and who demonstrate clinically significant improvement in spasticity-related symptoms during an initial trial of therapy.

Over the past couple of years, Sativex has been approved for use in a number of European countries and ongoing postmarketing studies are evaluating the possible risks associated with Sativex treatment by systematically collecting all suspected adverse reactions that occur in patients from the start of treatment. Interim data from the UK as well as Spanish Sativex safety registries confirm that clinical benefit is maintained over the longer term despite the expected trend for deterioration owing to disease progression.

 Even after more than 2 years of use, no new safety/tolerability signals have emerged with Sativex, including no evidence of driving impairment and no relevant incidence of falls or other adverse events of concern, such as psychiatric or nervous system events.

Sativex appears to be a well-tolerated and useful add-on therapy in patients who have not achieved an adequate response with traditional antispastic agents.”

“Advocates are fighting to legalize marijuana. The University of Mississippi has the only legally grown marijuana crop in the nation.Faculty members and student researchers have now developed a new patch that could potentially provide help to patients who need it.

The patch developed at Ole Miss could help patients overcome problems associated with taking the drug in pill form. The patch is placed above the gum line.

“In addition to pain, it will include things like reducing intraocular pressure and therefore would be good for glaucoma. [It] will be good for alleviating the nausea and vomiting associated with chemotherapy; it would also be good for appetite stimulation for patients suffering from the syndrome, anti-inflammatory activity, anti-anxiety,” explains Dr. ElSohly.”

“(WMC-TV) – Ole Miss is home to the only legally grown marijuana crop in the nation and a new development there is creating quite a buzz. Faculty and student researchers say they created a new pain reliever in the form of a patch.

Dr. Mahmoud Elsohly is a faculty member at the School of Pharmacy at Ole Miss. He and his team have been working inside their marijuana research lab for nearly seven years to find alternative uses for THC, which is the main psychoactive ingredient in marijuana.

“The plant itself has a great potential for good medicine coming out of the Cannabis plant…”

Cannabis and Δ(9)-tetrahydrocannabinol (THC) for weight loss?

Posted on by
Reply

“Obesity is one of the highest preventable causes of morbidity and mortality in the developed world. It has been well known for a long time that exposure to cannabis produces an increase of appetite (a phenomenon referred to as the ‘munchies’).

This phenomenon led to an exploration of the role of the endocannabinoid system in the regulation of obesity and associated metabolic syndrome. This effort subsequently led to the development of a successful therapeutic approach for obesity that consisted of blocking the cannabinoid CB(1) receptors using ligands such as Rimonabant in order to produce weight loss and improve metabolic profile. Despite being efficacious, Rimonabant was associated with increased rates of depression and anxiety and therefore removed from the market.

We recently discovered that the prevalence of obesity is paradoxically much lower in cannabis users as compared to non-users and that this difference is not accounted for by tobacco smoking status and is still present after adjusting for variables such as sex and age.

 Here, we propose that this effect is directly related to exposure to the Δ(9)-tetrahydrocannabinol (THC) present in cannabis smoke. We therefore propose the seemingly paradoxical hypothesis that THC or a THC/cannabidiol combination drug may produce weight loss and may be a useful therapeutic for the treatment of obesity and its complications.”

Cannabis compound can help cells

“Cannabis has been used recreationally and for medicinal purposes for centuries, yet its 60 plus active components are only partly understood. Now scientists have discovered how a compound in cannabis can help cells to function in our bodies, and aid recovery after a damaging event.

In a paper published in the Journal of Neuroscience, the researchers report on their studies into cannabidiol – a naturally occurring molecule found in cannabis.

Also known as CBD, it is not the constituent that gives the high – that compound is called tetrahydrocannabinol or THC – and so may be more acceptable as a drug treatment.

Both compounds are currently used in a pharmaceutical medicine to help patients relieve pain and other symptoms of Multiple Sclerosis.

Now researchers have discovered how CBD actually works within brain cells.

By interacting with mitochondria – which are the power generators of all cells – it can help maintain normal levels of calcium allowing cells to function properly and providing a greater resistance to damage.

Disturbance of calcium levels has long been associated with a number of brain disorders. So the finding could have implications for the development of new treatments for disorders related to malfunctioning mitochondria.

Dr Bettina Platt, from the University’s School of Medical Sciences, said: “Scientists have known for a long time that cannabidiol can help with pain relief but we never really knew how it worked.

“However we have discovered what it actually does at the cellular level.

“We are hoping that our findings can instruct the development of cannabidiol based treatments for disorders related to mitochondrial dysfunction such as Parkinson’s disease or Huntington’s disease.”

Israeli Study Finds Patients with Chronic Disease Benefit from Marijuana

“A new study out of Israel looks to change that. Led by Zach Klein, a specialist in medical marijuana policy and the director of the documentary Prescribed Grass, researchers at Tel Aviv University tested medical marijuana on 19 nursing home residents. Patients were treated with cannabis in the form of powder, oil, vapor, or smoke three times daily over the course of a year.

 Seventeen of the 19 patients regained lost weight, and symptoms of pain, stiffness, tremors, insomnia, and PTSD decreased drastically. Their moods and communication skills also improved, and they had fewer nightmares and flashbacks, according to Klein.

“After I found this, everything has been better,” Moshe Rute, a Holocaust survivor stricken by nightmares and the effects of a stroke told the Times of Israel. “I’m still a Holocaust child, but I’m finally able to better cope.”

The 80-year-old Hadarim resident is one of 11,000 Israelis with permits from the government to use marijuana for medical purposes, a number that is growing rapidly.

“This is just the tip of the iceberg. It’s the future,” Klein said to the Times. “This is God’s doing, and it’s marvelous in our eyes.”

Perhaps as important as the improvement in pain management and quality of life was marijuana’s ability to replace some of the medication taken by the patients. By the end of the study, 72 percent were able to reduce the number of drugs they were taking daily. This includes medication for Parkinson’s disease, pain relievers, antipsychotics, and mood stabilizers, many of which can have debilitating and severe side effects.

“We know how to extend life, but sometimes it’s not pleasant and can cause a great deal of suffering, so we’re looking to alleviate this, to add quality to longevity,” head nurse Inbal Sikorin told the Times. “Cannabis meets this need. Almost all our patients are eating again, and their moods have improved tremendously.”

The country that discovered tetrahydrocannabinol (THC) the psychoactive ingredient in cannabis, in the 1960’s doesn’t have the stigma attached to marijuana that the United States does, as even senior rabbis have no qualms with its use or spread.

Klein is working on a new study at Israel’s Reuth Medical Center, in which he hopes to establish a connection between medical cannabis and improved swallowing. One of the biggest concerns with chronically ill patients is food intake, and Klein believes that cannabis, which can stimulate regions of the brain associated with swallowing reflexes, will have a positive impact.”

“It makes most people a little foggy-headed, but scientists are investigating whether an active ingredient in cannabis could actually stave off dementia.

A team from Neuroscience Research Australia is in the early stages of research examining if one of the main active ingredients in cannabis, called cannabidiol, could reverse some of the symptoms of memory loss in animals.

Tim Karl, a senior research fellow with the group, said cannabidiol does not have the same psychoactive effects as the main component of marijuana, THC, but it has been found to have anti-inflammatory, antioxidant and other effects that could be beneficial for the brain.”

“Neuroscientists suspect the main active ingredient in cannabis, called cannabidiol, could help prevent or reverse early stage brain damage and memory loss from Alzheimer’s disease, according to Australian newspaper the Sydney Morning Herald.

Tim Karl, a senior research fellow with Neuroscience Research Australia, said cannabidiol doesn’t have the same psychoactive effects as marijuana’s main component, THC (meaning it won’t get you high), but it does have anti-inflammatory, antioxidant and possible brain protective effects.

“Back in the day cannabis was used for medical purposes,” he said. “I’m talking 200 years, 100 years back, then at some point people discovered it had other effects and, as quite often happens in our society, people decided it was a bad drug.

But (cannabis isn’t) one compound, it is a mixture of 60 different compounds, and you just have to look at those different compounds because some of them might be good for you.””

The pharmacologic and clinical effects of medical cannabis.

Posted on by

“Cannabis, or marijuana, has been used for medicinal purposes for many years. Several types of cannabinoid medicines are available in the United States and Canada. Dronabinol (schedule III), nabilone (schedule II), and nabiximols (not U.S. Food and Drug Administration approved) are cannabis-derived pharmaceuticals.

Medical cannabis or medical marijuana, a leafy plant cultivated for the production of its leaves and flowering tops, is a schedule I drug, but patients obtain it through cannabis dispensaries and statewide programs. The effect that cannabinoid compounds have on the cannabinoid receptors (CB(1) and CB(2) ) found in the brain can create varying pharmacologic responses based on formulation and patient characteristics. The cannabinoid Δ(9) -tetrahydrocannabinol has been determined to have the primary psychoactive effects; the effects of several other key cannabinoid compounds have yet to be fully elucidated. Dronabinol and nabilone are indicated for the treatment of nausea and vomiting associated with cancer chemotherapy and of anorexia associated with weight loss in patients with acquired immune deficiency syndrome. However, pain and muscle spasms are the most common reasons that medical cannabis is being recommended.

Studies of medical cannabis show significant improvement in various types of pain and muscle spasticity. Reported adverse effects are typically not serious, with the most common being dizziness. Safety concerns regarding cannabis include the increased risk of developing schizophrenia with adolescent use, impairments in memory and cognition, accidental pediatric ingestions, and lack of safety packaging for medical cannabis formulations. This article will describe the pharmacology of cannabis, effects of various dosage formulations, therapeutics benefits and risks of cannabis for pain and muscle spasm, and safety concerns of medical cannabis use.”
