Higher quality, long-term, randomized controlled trials are needed to examine whether cannabinoids administered by routes other than inhalation and oral routes may have a role in the treatment of neuropathic pain. Can Fam Physician. evaluated the use of intramuscular levonantradol versus placebo in acute postoperative pain [47]. Patients who received selective cannabinoids reported a significant, but clinically small, reduction in mean numerical rating scale pain scores (0-10 scale) compared with comparator groups (0.65 points; 95% confidence interval, 1.06 to 0.23 points; P = .002, I2 = 60%; Grade of Recommendations Assessment, Development, and Evaluation: weak reco.

Study Finds Cannabinoids May Be Powerful Alternative to Opioids for Clinical Studies Different. Friedman D., French J.A., Maccarrone M. Safety, efficacy, and mechanisms of action of cannabinoids in neurological disorders. The approach with the best results is the multidisciplinary approach combining pharmacological, physical, and psychological interventions [25,26]. All trials used whole cannabis plant provided by NIDA, and the main outcomes were patient-reported pain scales. Neuropathic pain is often refractory to conventional pharmacotherapies, necessitating validation of novel analgesics. Research has been done on the effects of cannabis or cannabinoids on chronic pain, particularly neuropathic pain (pain associated with nerve injury or damage). Long-term use may lead to addiction and cognitive impairment.12,13.
Cannabis-Based Medicines and Medical Cannabis for Chronic Neuropathic Pain Because they do not focus on neuropathic pain, they are excluded. Patel A.D., Mazurkiewicz-Bedziska M., Chin R.F., Gil-Nagel A., Gunning B., Halford J.J., Mitchell W., Scott Perry M., Thiele E.A., Weinstock A., et al. There is no evidence to support the use of conventional analgesics such as paracetamol or non-steroidal anti-inflammatory drugs (NSAIDs) in the treatment of chronic neuropathic pain [16]. Administration in a double-blind study of different single intramuscular doses of levonantradol (n = 40), an analog of the cannabinoid dronabinol, or placebo (n = 16) to 56 patients with moderate to severe postoperative or traumatic pain showed significant analgesic effects in comparison with placebo (p < 0.05) [47]. Using screening tools to identify neuropathic pain. Efficacy of the topical 5% lidocaine medicated plaster in the treatment of chronic post-thoracotomy neuropathic pain. The prevalence is higher in certain populations, with 26% of people over age 65 and 30% of patients with diabetes mellitus affected.24. The potential benefits of cannabis-based medicine (herbal cannabis, plant-derived or synthetic tetrahydrocannabinol (THC), THC/cannabidiol (CBD) oromucosal spray) in chronic neuropathic pain might be outweighed by their potential harms [36].

However, although statistically significant, the differences reported in the Table 2 of Xu et al. Most studies show moderately improved pain from inhaled cannabis use, but adverse effects such as impaired cognition and respiratory problems are common, especially at high doses.

Chronic pain, particularly neuropathic pain, is a major clinical problem that is difficult to treat ().Despite an intensive search for new analgesics in the last several decades, the need for novel therapeutic strategies remains unmet because virtually every blockbuster drug for the treatment of chronic pain produces aversive side effects (Mogil, 2009; Harrison, 2011). Cannabinoids for the treatment of neuropathic pain: clinical evidence. Small clinical studies have found that cannabis provides benefits for peripheral neuropathy, including pain reduction, better sleep, and improved function, even in patients with symptoms refractory to standard therapies.
