THC:CBD Spray and MS Spasticity Symptoms: Data from Latest Studies.

“New clinical experience with 9-delta-tetrahydocannabinol (THC) and cannabidiol (CBD) oromucosal spray (Sativex®)…

A randomized, placebo controlled long-term follow-up clinical trial with THC:CBD spray versus placebo demonstrated that it was not associated with cognitive decline, depression or significant mood changes…

THC:CBD oromucosal spray did not adversely influence standard driving ability in patients with moderate to severe MS spasticity…

Findings to date reinforce the efficacy and safety observed in Phase III clinical trials…

Importantly, no additional safety concerns were identified…

Thus, these new data support a positive benefit-risk relationship for THC:CBD oromucosal spray during longer-term use.”

Nabiximols as an Agonist Replacement Therapy During Cannabis Withdrawal: A Randomized Clinical Trial.

“The cannabis extract nabiximols (Sativex), developed as a multiple sclerosis treatment, offers a potential agonist medication for cannabis withdrawal…

Nabiximols treatment significantly reduced the overall severity of cannabis withdrawal…

The data support further evaluation of nabiximols for management of cannabis dependence and withdrawal in treatment-seeking populations.”

A double-blind, randomized, placebo-controlled, parallel group study of THC/CBD spray in peripheral neuropathic pain treatment.

“Peripheral neuropathic pain (PNP) associated with allodynia poses a significant clinical challenge. The efficacy of Δ9 -tetrahydrocannabinol/cannabidiol (THC/CBD) oromucosal spray, a novel cannabinoid formulation, was investigated in this 15-week randomized, double-blind, placebo-controlled parallel group study…

These findings demonstrate that, in a meaningful proportion of otherwise treatment-resistant patients, clinically important improvements in pain, sleep quality and SGIC of the severity of their condition are obtained with THC/CBD spray. THC/CBD spray was well tolerated and no new safety concerns were identified.”

Cannabidiol protects liver from binge alcohol-induced steatosis by mechanisms including inhibition of oxidative stress and increasing of autophagy.

“Acute alcohol drinking induces steatosis, and effective prevention of steatosis can protect liver from progressive damage caused by alcohol… We evaluated whether cannabidiol, which has been reported to function as an antioxidant, can protect the liver from alcohol-generated oxidative stress induced steatosis.

Cannabidiol can prevent acute alcohol induced liver steatosis in mice… Importantly, cannabidiol can prevent the decrease of autophagy induced by alcohol.

In conclusion, these results show that cannabidiol protects mouse liver from acute alcohol induced steatosis through multiple mechanisms including attenuation of alcohol-mediated oxidative stress, prevention of JNK MAPK activation, and increasing autophagy.”

Clinical experience with THC:CBD oromucosal spray in patients with multiple sclerosis-related spasticity.

“This detailed medical charts’ data collection study conducted at an MS clinic in Germany evaluated the effectiveness of tetrahydrocannabinol (THC) / cannabidiol (CBD) oromucosal spray in patients with resistant multiple sclerosis (MS) spasticity…

In this routine clinical practice setting at an MS clinic in Germany, THC:CBD spray was effective and well tolerated as add-on therapy or as monotherapy in a relevant proportion of patients with resistant MS spasticity.”

Sativex(®) (tetrahydrocannabinol + cannabidiol), an endocannabinoid system modulator: basic features and main clinical data.

“Sativex(®) (nabiximols, USAN name) oromucosal spray contains the two main active constituents of Cannabis sativa, tetrahydrocannabinol and cannabidiol in a 1:1 molecular ratio, and acts as an endocannabinoid system modulator. Randomized, controlled clinical trials of Sativex as add-on therapy provide conclusive evidence of its efficacy in the treatment of more than 1500 patients with multiple sclerosis (MS)-related resistant spasticity…

Sativex oromucosal spray appears to be a useful and welcomed option for the management of resistant spasticity in MS patients. Although the management of MS has been improved by the availability of disease-modifying agents that target the underlying pathophysiological processes of the disease, a clear need remains for more effective symptomatic treatments, especially as regards MS-related spasticity and pain.”

Endocannabinoid pathways and their role in multiple sclerosis-related muscular dysfunction.

“Modulation of the endocannabinoid system has been shown to have therapeutic potential in a number of disease states.

Sativex(®) (nabiximols, USAN name) contains the two main phytocannabinoids from Cannabis sativa, tetrahydrocannabinol and cannabidiol in a 1:1 ratio, and it acts as an endocannabinoid system modulator.

In an experimental mouse model of MS-related spasticity, Sativex dose-dependently improved hind limb flexion/stiffness and a dosage of 10 mg/kg was shown to be as effective as the most widely established anti-spasticity treatment baclofen (5 mg/kg).

These findings with Sativex are very promising and offer encouragement for MS patients, the majority of whom will develop spasticity-related disabling and recalcitrant symptoms. Furthermore, research into the endocannabinoid system may offer potential in other neurodegenerative, inflammatory and pain disorders.”

Inhibition of colon carcinogenesis by a standardized Cannabis sativa extract with high content of cannabidiol.

“Colon cancer is a major public health problem. Cannabis-based medicines are useful adjunctive treatments in cancer patients. Here, we have investigated the effect of a standardized Cannabis sativa extract with high content of cannabidiol (CBD), here named CBD BDS, i.e. CBD botanical drug substance, on colorectal cancer cell proliferation and in experimental models of colon cancer in vivo.

RESULTS:

CBD BDS and CBD reduced cell proliferation in tumoral, but not in healthy, cells… In vivo, CBD BDS reduced AOM-induced preneoplastic lesions and polyps as well as tumour growth in the xenograft model of colon cancer.

CONCLUSIONS:

CBD BDS attenuates colon carcinogenesis and inhibits colorectal cancer cell proliferation via CB1 and CB2 receptor activation. The results may have some clinical relevance for the use of Cannabis-based medicines in cancer patients.”

Effects of intra-prelimbic prefrontal cortex injection of cannabidiol on anxiety-like behavior: Involvement of 5HT1A receptors and previous stressful experience.

“The prelimbic medial prefrontal cortex (PL) is an important encephalic structure involved in the expression of emotional states. In a previous study, intra-PL injection of cannabidiol (CBD), a major non-psychotomimetic cannabinoid present in the Cannabis sativa plant, reduced the expression of fear conditioning response…

CBD caused an anxiolytic, rather than anxiogenic, effect…

Taken together, these results suggest that CBD modulation of anxiety in the PL depend on 5HT1A-mediated neurotransmission and previous stressful experience.”

Cannabidiol as a potential treatment for psychosis.

“…the cannabis constituent cannabidiol (CBD) may have antipsychotic properties.

This review concisely describes the role of the endocannabinoid system in the development of psychosis and provides an overview of currently available animal, human experimental, imaging, epidemiological and clinical studies that investigated the antipsychotic properties of CBD…

Evidence from several research domains suggests that CBD shows potential for antipsychotic treatment.”
