Palatability and oral cavity tolerability of THC:CBD oromucosal spray and possible improvement measures in multiple sclerosis patients with resistant spasticity: a pilot study.

Future Medicine Logo

“Complaints about Δ9-tetrahydrocannabinol (THC):cannabidiol (CBD) oromucosal spray (Sativex®; GW Pharma Ltd, Sailsbury, UK) in the management of multiple sclerosis spasticity include unpleasant taste and oral mucosal anomalies.

This pilot study assessed the use of sugar-free chewing gum and/or a refrigerated bottle of THC:CBD oromucosal spray to mitigate these effects.

RESULTS:

Taste perception in patients receiving chewing gum ± cold bottle intervention (Groups A and C combined) was significantly (p = 0.0001) improved from baseline to week 4 while maintaining spasticity control.

CONCLUSION:

Patient comfort, satisfaction and treatment adherence may benefit from these interventions.”

Hemp shows potential for treating ovarian cancer

“Researchers demonstrate hemp’s ability to slow cancer growth and uncover mechanism for its cancer-fighting ability.

Results from some of the first studies to examine hemp’s ability to fight cancer show that it might one day be useful as plant-based treatment for ovarian cancer. Hemp is part of the same cannabis family as marijuana but doesn’t have any psychoactive properties or cause addiction.

“Hemp, like marijuana, contains therapeutically valuable components such as cannabidiol, cannabinol, and tetrahydrocannabinol,”

“Our findings from this research as well as prior research show that KY hemp slows ovarian cancer comparable to or even better than the current ovarian cancer drug Cisplatin,” said Turner. “Since Cisplatin exhibits high toxicity, we anticipate that hemp would carry less side effects.”

Cannabidiol Based Medical Cannabis in Children with Autism- a Retrospective Feasibility Study

Home

“Objective: This retrospective study assessed safety, tolerability and efficacy of cannabidiol (CBD) based medical cannabis, as an adjuvant therapy, for refractory behavioral problems in children with ASD.

Background: Anecdotal evidence of successful cannabis treatment in children with autism spectrum disorder (ASD) are accumulating but formal studies are lacking.

Design/Methods: Sixty children with ASD (age = 11.8± 3.5, range 5.0–17.5; 77% low functioning; 83% boys) were treated with oral CBD and tetrahydrocannabinol (THC) at a ratio of 20:1. The dose was up-titrated to effect (maximal CBD dose − 10mg/kg/d). Tolerability and efficacy were assessed using a modified Liverpool Adverse Events Profile, the Caregiver Global Impression of Change (CGIC) scale, the Home Situations Questionnaire–Autism Spectrum Disorder (HSQ-ASD) and the Autism Parenting Stress Index (APSI).

Results: Following the cannabis treatment, behavioral outbreaks were much improved or very much improved (on the CGIC scale) in 61% of patients. The anxiety and communication problems were much or very much improved in 39% and 47% respectively. Disruptive behaviors, were improved by 29% from 4.74±1.82 as recorded at baseline on the HSQ-ASD to 3.36±1.56 following the treatment. Parents reported less stress as reflected in the APSI scores, changing by 33% from 2.04±0.77 to 1.37±0.59. The effect on all outcome measures was more apparent in boys with non-syndromic ASD. Adverse events included sleep disturbances (14%) irritability (9%) and loss of appetite (9%).

Conclusions: This preliminary study support the feasibility of CBD based medical cannabis as a promising treatment option for refractory behavioral problems in children with ASD. Based on these promising results, we have launched a large, double blind, placebo controlled cross-over trial with 120 participants (NCT02956226).”

Dronabinol oral solution in the management of anorexia and weight loss in AIDS and cancer.

“The true incidence of anorexia secondary to human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) and cancer is not well classified owing to the fact that there is a lack of standardized definitions and recent clinical data in these settings.

Dronabinol, or Δ-9-tetrahydrocannabinol, is a synthetic molecule that closely mimics the action of Cannabis sativa L., a naturally occurring compound activated in the central nervous system by cannabinoid receptors.

Dronabinol exerts its effects by directly acting on the vomiting and appetite control centers in the brain, which in turn increases appetite and prevents vomiting.

In the USA, dronabinol is currently available in two dosage formulations – oral capsule and oral solution. While the oral capsule was initially approved by the US Food and Drug Administration in 1985, the recent approval of the oral solution in 2016 presents an “easy-to-swallow” alternative for patients using or intending to use dronabinol.

Dronabinol is indicated in adult patients with HIV/AIDS for the treatment of anorexia and weight loss. However, there is no approved indication in the setting of cancer-related anorexia and weight loss. This review aims at presenting available data on the use of oral dronabinol in the management of anorexia and weight loss in HIV/AIDS and cancer, as well as characterizing and highlighting the pharmacotherapeutic considerations of the newest formulation of dronabinol.”

A Naturalistic Examination of the Perceived Effects of Cannabis on Negative Affect

Cover image

“Cannabis is commonly used to alleviate symptoms of negative affect. However, a paucity of research has examined the acute effects of cannabis on negative affect in everyday life.

The current study provides a naturalistic account of perceived changes in symptoms of depression, anxiety, and stress as a function of dose and concentration of Δ9tetrahydrocannabinol (THC) and cannabidiol (CBD).

Cannabis is commonly used to alleviate depression, anxiety, and stress. Indeed, one of the most commonly reported motives for cannabis use is to cope with stress, with 72% of daily cannabis users reporting use of cannabis to relax or relieve tension.

Results from the present study indicate that medical cannabis users report a substantial and significant reduction in symptoms of negative affect shortly after using cannabis.”

The use of cannabis in supportive care and treatment of brain tumor

Issue Cover

“Anticancer Effects of Cannabinoids may be able to Prolong Life.

Cannabinoids are multitarget substances. Currently available are dronabinol (synthetic delta-9-tetrahydrocannabinol, THC), synthetic cannabidiol (CBD) the respective substances isolated and purified from cannabis, a refined extract, nabiximols (THC:CBD = 1.08:1.00); and nabilone, which is also synthetic and has properties that are very similar to those of THC.

Cannabinoids have a role in the treatment of cancer as palliative interventions against nausea, vomiting, pain, anxiety, and sleep disturbances. THC and nabilone are also used for anorexia and weight loss, whereas CBD has no orexigenic effect. The psychotropic effects of THC and nabilone, although often undesirable, can improve mood when administered in low doses. CBD has no psychotropic effects; it is anxiolytic and antidepressive.

Of particular interest are glioma studies in animals where relatively high doses of CBD and THC demonstrated significant regression of tumor volumes (approximately 50% to 95% and even complete eradication in rare cases). Concomitant treatment with X-rays or temozolomide enhanced activity further. Similarly, a combination of THC with CBD showed synergistic effects. Although many questions, such as on optimized treatment schedules, are still unresolved, today’s scientific results suggest that cannabinoids could play an important role in palliative care of brain tumor patients.

THC, a partial CB1, CB2 agonist, has the stigma of psychotropic effects that are mediated by CB1 stimulation. However, CB1 stimulation is necessary for improving mood and appetite and many other effects. At present, it is hard to imagine a better approach than adjusting THC doses individually to balance wanted versus unwanted effects. Generally, higher doses are needed to achieve analgesic and antiemetic effects. Even much higher, supraphysiologic oral doses would be needed to combat tumors.

Combinations were synergistic under many circumstances such as in pain and antitumor studies. Cannabinoids differ in their antitumor activities and probably in their mechanisms and targets, which is a rationale for combinations. However, for many pharmacological effects (except against tumors) roughly 10-times higher daily doses are needed for CBD compared to THC.

In summary, the endocannabinoid system is likely playing a crucial role in palliative care. The future will show whether an optimized treatment strategy with cannabinoids can also prolong life of brain tumor patients by their virtue to combat cancer cells.”

The Endocannabinoid System, Aggression, and the Violence of Synthetic Cannabinoid Use, Borderline Personality Disorder, Antisocial Personality Disorder, and Other Psychiatric Disorders

Image result for frontiers in behavioral neuroscience

“While most human research has concluded that the active ingredient of marijuana, Δ9-tetrahydrocannabinol, tends to dampen rather than provoke aggression in acute doses, recent evidence supports a relationship between the ingestion of synthetic cannabinoids and emergence of violent or aggressive behavior.

To summarize, this paper will draw upon basic and clinical research to explain how the endocannabinoid system may contribute to the genesis of aggressive behavior.”

Therapeutic cannabinoids in multiple sclerosis: immunomodulation revisited.

Publication cover image

Cannabinoids are compounds with pleiotropic properties that act on the cannabinoid receptors, CB1 and CB2, and are divided into endocannabinoids, the endogenous ligands of these receptors, synthetic cannabinoids and phytocannabinoids.

The latter are derived from the plant Cannabis sativa. The therapeutic and psychoactive properties of this plant have been observed and used for centuries.

Of the over 60 compounds that are unique to Cannabis sativa, the substances that have been attributed the greatest therapeutic potential are Δ9 – tetrahydrocannabinol (THC) and cannabidiol (CBD), both of which, used alone or combined with each other, have become approved drugs.”

Cannabis Essential Oil: A Preliminary Study for the Evaluation of the Brain Effects.

Image result for Evid Based Complement Alternat Med

“We examined the effects of essential oil from legal (THC <0.2% w/v) hemp variety on the nervous system in 5 healthy volunteers. GC/EIMS and GC/FID analysis of the EO showed that the main components were myrcene and β-caryophyllene.

The experiment consisted of measuring autonomic nervous system (ANS) parameters; evaluations of the mood state; and electroencephalography (EEG) recording before treatment, during treatment, and after hemp inhalation periods as compared with control conditions. The results revealed decreased diastolic blood pressure, increased heart rate, and significant increased skin temperature.

The subjects described themselves as more energetic, relaxed, and calm.

The analysis EEG showed a significant increase in the mean frequency of alpha (8-13 Hz) and significant decreased mean frequency and relative power of beta 2 (18,5-30 Hz) waves. Moreover, an increased power, relative power, and amplitude of theta (4-8 Hz) and alpha brain waves activities and an increment in the delta wave (0,5-4 Hz) power and relative power was recorded in the posterior region of the brain.

These results suggest that the brain wave activity and ANS are affected by the inhalation of the EO of Cannabis sativa suggesting a neuromodular activity in cases of stress, depression, and anxiety.”
