Evidence for the efficacy and effectiveness of THC-CBD oromucosal spray in symptom management of patients with spasticity due to multiple sclerosis.

Posted on January 21, 2016 by David

“Spasticity, one of the main symptoms of multiple sclerosis (MS), can affect more than 80% of MS patients during the course of their disease and is often not treated adequately.

δ-9-Tetrahydrocannabinol-cannabidiol (THC-CBD) oromucosal spray is a plant-derived, standardized cannabinoid-based oromucosal spray medicine for add-on treatment of moderate to severe, resistant multiple sclerosis-induced spasticity.

This article reviews the current evidence for the efficacy and safety, with dizziness and fatigue as the most common treatment-related adverse events, being mostly mild to moderate in severity.

Results from both randomized controlled phase III studies involving about,1600 MS patients or 1500 patient-years and recently published studies on everyday clinical practice involving more than 1000 patients or more than,1000 patient-years are presented.”

The Pharmacological Basis of Cannabis Therapy for Epilepsy.

Posted on January 21, 2016 by David

“Recently, cannabis has been suggested as a potential alternative therapy for refractory epilepsy, which affects 30% of epilepsy patients including children who do not respond to current medications.

There is a large unmet medical need for new antiepileptics for refractory epilepsy and conditions associated with refractory seizures that would not interfere with normal function.

The two chief cannabinoids are delta-9-tetrahyrdrocannabinol, the major psychoactive component of marijuana, and cannabidiol (CBD), the major non-psychoactive component of marijuana.

There are claims of clinical efficacy of CBD-predominant cannabis or medical marijuana for epilepsy, mostly from limited studies, surveys or case reports.

However, the mechanisms underlying the antiepileptic efficacy of cannabis remain unclear. This article highlights the pharmacological basis of cannabis therapy, with an emphasis on the endocannabinoid mechanisms underlying the emerging neurotherapeutics of CBD in epilepsy.

CBD is anticonvulsant, but it has a low affinity for the cannabinoid CB1 and CB2 receptors; therefore the exact mechanism by which it affects seizures remains poorly understood.

A rigorous clinical evaluation of pharmaceutical CBD products is needed to establish the safety and efficacy for the treatment of epilepsy.

Identification of mechanisms underlying the anticonvulsant efficacy of CBD is additionally critical to identify other potential treatment options.”

The endocannabinoid system and neuropathic pain.

Posted on January 20, 2016 by David

“The research of new therapeutic strategies for neuropathic pain represents a major current priority.

Important drawbacks to advance in the development of these therapies are the limited translational value of the animal models now available and the elucidation of the complex neuronal and immune pathophysiological mechanisms underlying neuropathic pain.

One of the neurotransmitter systems participating in neuropathic pain control that has recently raised a particular interest is the endocannabinoid system.

This system is highly expressed in neurons and immune cells, and it plays a crucial role in the development of neuropathic pain.

Preclinical studies have provided important findings, revealing the potential interest of the endocannabinoid system for the treatment of neuropathic pain.

These studies have reported the analgesic effects of cannabinoid agonists in multiple neuropathic pain models, and they have identified specific targets within this system to develop more effective and safe analgesic compounds.

Several clinical studies suggest that cannabinoids significantly reduced neuropathic pain…“

Role of hypothalamic cannabinoid receptors in post-stroke depression in rats.

Posted on January 19, 2016 by David

“One of the most common psychological consequences of stroke is post-stroke depression (PSD). While more than 30 percent of stroke patients eventually develop PSD, the neurobiological mechanisms underlying such a phenomenon have not been well investigated.

Given the critical involvement of hypothalamic-pituitary-adrenal axis and endocannabinoid system in response to stressful stimuli, we evaluated the hypothesis that cannabinoid receptors in the hypothalamus are critical for modulation of post-stroke depression-like behaviors in rats.

Taken together, these results suggest that decreased CB1 receptor expression is likely associated with the development of post-stroke depression, and CB2 receptor may be a potential therapeutic target for the treatment post-stroke depressive disorders.”

Cannabidiol limits Tcell-mediated chronic autoimmune myocarditis: implications to autoimmune disorders and organ transplantation.

Posted on January 17, 2016 by David

“Myocarditis is a major cause of heart failure and sudden cardiac death in young adults and adolescents. Many cases of myocarditis are associated with autoimmune processes in which cardiac myosin is a major autoantigen.

Conventional immunosuppressive therapies often provide unsatisfactory results and are associated with adverse toxicities during the treatment of autoimmune myocarditis.

Cannabidiol (CBD) is a non-psychoactive constituent of Marijuana which exerts antiinflammatory effects independent from classical cannabinoid receptors.

Recently 80 clinical trials have been reported investigating the effects of CBD in various diseases from inflammatory bowel disease to graft-versus-host disease.

CBD-based formulations are used for the management of multiple sclerosis in numerous countries, and CBD also received FDA approval for the treatment of refractory childhood epilepsy and glioblastoma multiforme.

Herein, using a well-established mouse model of experimental autoimmune myocarditis (EAM) induced by immunization with cardiac myosin emmulsified in adjuvant resulting in T cell-mediated inflammation, cardiomyocyte cell death, fibrosis and myocardial dysfunction, we studied the potential beneficial effects of CBD…

CBD may represent a promising novel treatment for management of autoimmune myocarditis and possibly other autoimmune disorders, and organ transplantation.”

Image result for Life Sci.

“Cannabinoid compounds are unique to cannabis and provide some interesting biological properties.

These compounds along with endocannabinoids, a group of neuromodulator compounds in the body especially in brain, express their effects by activation of G-protein-coupled cannabinoid receptors, CB1 and CB2.

There are several physiological properties attributed to the endocannabinoids including pain relief, enhancement of appetite, blood pressure lowering during shock, embryonic development, and blocking of working memory.

On the other hand, activation of endocannabinoid system may be suppresses evolution and progression of several types of cancer.

According to the results of recent studies, CB receptors are over-expressed in cancer cell lines and application of multiple cannabinoid or cannabis-derived compounds reduce tumor size through decrease of cell proliferation or induction of cell cycle arrest and apoptosis along with desirable effect on decrease of tumor-evoked pain.

Therefore, modulation of endocannabinoid system by inhibition of fatty acid amide hydrolase (FAAH), the enzyme, which metabolized endocannabinoids, or application of multiple cannabinoid or cannabis-derived compounds, may be appropriate for the treatment of several cancer subtypes. This review focuses on how cannabinoid affect different types of cancers.”

A cost-effectiveness model for the use of a cannabis-derived oromucosal spray for the treatment of spasticity in multiple sclerosis.

Posted on January 12, 2016 by David

“Severity of spasticity in multiple sclerosis (MS) directly correlates with the level and cost of care required.

This study assessed whether a tetrahydrocannabinol/cannabidiol (THC/CBD) oromucosal spray for treatment of moderate-severe MS spasticity is a cost-effective use of healthcare resources in Wales.

The THC/CBD spray was found to be cost-effective for the treatment of spasticity in MS, and dominant, if home carer costs were included.

Use of THC/CBD has the potential to generate cost savings by significantly improving the symptoms of moderate to severe MS spasticity”

The Use of Marijuana or Synthetic Cannabinoids for the Treatment of Headache

Posted on January 11, 2016 by David

“Although marijuana is principally used as a psychoactive substance, it has also been used for medical and religious purposes for over 2000 years.

This review concluded that there was evidence of a positive and moderate short-term trend toward a reduction of pain.

There are a number of reasons why naturally occurring cannabis or cannabinoid drugs might have a pharmacologic effect on headache..

It has been suggested that one explanation for migraine and other headache disorders may be an underlying endocannabinoid deficiency.

…cluster headache attacks were relieved within 5 minutes by the inhalation of marijuana.

Subsequent treatment with dronabinol (THC) 5 mg orally also provided the patient relief within 15 minutes.”
