Physicians should know both the scientific rationale and the practical implications for medical marijuana laws. Objective  To review the pharmacology, indications, and laws related to medical marijuana use. Evidence Review  The medical literature on medical marijuana was reviewed from 1948 to March 2015 via MEDLINE with an emphasis on 28 randomized clinical trials of cannabinoids as pharmacotherapy for indications other than those for which there are 2 US Food and Drug Administration–approved cannabinoids (dronabinol and nabilone), which include nausea and...

Abstract Delta-9-tetrahydrocannabinol (THC)/cannabidiol (CBD) oromucosal spray was approved as add-on therapy for spasticity in patients with multiple sclerosis (MS). We show our 40-week postmarketing experience regarding efficacy and safety of THC/CBD spray in an Italian cohort of 102 MS patients. Patients were evaluated using the Expanded Disability Status Scale (EDSS) score, the Numerical Rating Scale (NRS) for spasticity, the Ambulation Index (AI), and Timed 25-Foot Walk (T25-FW) at the beginning of treatment and then every 3 months. After 4 weeks, if a clinically significant improvement in spasticity (at least 20% of baseline NRS score) was not...

Mobility impairment after progressive paralyses and muscle tone spasticity is common. Areas covered: The prevalence, assessment, and pharmacological management of gait impairment and spasticity in MS and their effects on health-related quality of life (HRQoL) are discussed. The roles of oral and intrathecal baclofen and of delta-9-tetrahydrocannabinol/cannabidiol (THC:CBD) oromucosal spray in treating MS spasticity-related gait impairment are reviewed. Expert commentary: Mobility impairment and spasticity are experienced by approximately 90% and 80% of MS patients, respectively, during the disease course. Prevalence...

Due to strict regulations, only a minority of MS patients receive cannabis-based prescription drugs. The extent of recreational and medical cannabis use among Danes with MS is unknown. Our aim was to evaluate the prevalence of illegal and legal use of cannabis in MS patients, as well as reasons for use and perceived adverse effects. Methods An anonymous questionnaire was sent to all 3606 patients at the Danish Multiple Sclerosis Center, Rigshospitalet, University of Copenhagen. The questionnaire included questions about sociodemographic factors, clinical characteristics and medical...

Abstract Background Nabiximols (THC/CBD Oromucosal Spray, Sativex) is used as an add-on therapy to treat moderate to severe spasticity of Multiple Sclerosis (MS). Objectives To examine the impact of physiotherapy (PT) programs on effectiveness and persistence of nabiximols treatment in people with MS-related spasticity. Methods This is an observational multicenter study with a follow-up period of 12 weeks, conducted in routine care settings in Italy. Patients with moderate to severe MS-related spasticity who started nabiximols were included. Spasticity was evaluated by the patient-rated 0–10 numerical rating scale (NRS). Clinical data were collected at baseline (T0), 4 weeks (T1) and 12 weeks (T2) months after...

Abstract Background/purpose: Spasticity is one of the most common symptoms in people with multiple sclerosis (MS). Conventional anti-spasticity agents have limitations in their efficacy and tolerability. Delta-9-tetrahydrocannabinol: cannabidiol (THC:CBD) spray, a cannabinoid-based medicine, is approved as an add-on therapy for MS spasticity not adequately controlled by other anti-spasticity medications. The results from randomized controlled trials (RCTs) have demonstrated a reduction in the severity of spasticity and associated symptoms. However, RCTs do not always reflect real-life outcomes. We systematically reviewed the complementary evidence from non-interventional real-world studies. Methods: A systematic literature review was conducted to identify all non-RCT publications on THC:CBD spray between 2011 and...

Abstract Background Treatment of spasticity poses a major challenge in amyotrophic lateral sclerosis (ALS) patient management. Delta-9-tetrahydrocannabinol (THC):cannabidiol (CBD) oromucosal spray (THC:CBD), approved for the treatment of spasticity in multiple sclerosis, serves as a complementary off-label treatment option in ALS-related spasticity. However, few structured data are available on THC:CBD in the treatment of spasticity in ALS. Method A retrospective mono-centric cohort study was realised in 32 patients that meet the following criteria: 1) diagnosis of ALS, 2) ALS-related spasticity; 3) treatment with THC:CBD. Spasticity was rated using the Numeric Rating Scale (NRS). Patient’s experience with THC:CBD was assessed using the net promoter score (NPS)...

Abstract The use of medical cannabis in children is rapidly growing. While robust evidence currently exists only for pure cannabidiol (CBD) to treat specific types of refractory epilepsy, in most cases, artisanal strains of CBD-rich medical cannabis are being used to treat children with various types of refractory epilepsy or irritability associated with autism spectrum disorder (ASD). Other common pediatric disorders that are being considered for cannabis treatment are Tourette syndrome and spasticity. As recreational cannabis use during youth is associated with serious adverse events and medical cannabis use is believed to have a relatively high placebo effect, decisions to use medical cannabis during...

Abstract Objective: To determine whether differences in disability status, spasticity severity, and spasticity duration at treatment start in patients with resistant multiple sclerosis (MS) spasticity might influence response to add-on tetrahydrocannabinol:cannabidiol (THC:CBD) oromucosal spray (nabiximols) versus further re-adjustment of optimized first-line antispasticity medication. Methods: Using the database from the Sativex® as Add-on therapy Vs. further optimized first-line ANTispastics (SAVANT) study, this post hoc analysis evaluated spasticity severity (0-10 numerical rating scale [NRS] scores) and pain severity (0–10 NRS scores) evolution from randomization (baseline) to week 12 (end of double-blind treatment) in defined subgroups: Expanded disability status scale [EDSS] score...

Background: Spasticity is a disabling complication of multiple sclerosis, affecting many patients with the condition. We report the first Phase 3 placebo-controlled study of an oral antispasticity agent to use an enriched study design. Methods: A 19-week follow-up, multicentre, double-blind, randomized, placebo-controlled, parallel-group study in subjects with multiple sclerosis spasticity not fully relieved with current antispasticity therapy, Subjects were treated with nabiximols, as add-on therapy, in a single-blind manner for 4 weeks, after which those achieving an improvement in spasticity of 20% progressed to a 12-week randomized, placebo controlled phase. Results: Of the 572 subjects enrolled, 272 achieved a 20% improvement after 4 weeks...
