The researchers reported that dronabinol had a significant analgesic effect on central pain in patients with multiple sclerosis, although the effects were modest they were clinically relevant.

Dronabinol Is a Safe Long-Term Treatment Option for Neuropathic Pain Patients

The trial results demonstrate that dronabinol is a safe long-term treatment option and a positive benefit-risk ratio and no signs of drug abuse and only one possible case of dependency occurred.

Randomized, controlled trial of cannabis-based medicine in central pain in multiple sclerosis

CBM was generally well tolerated, although more patients on CBM than placebo reported dizziness, dry mouth, and somnolence, and Cognitive side effects were limited to long-term memory storage.

A randomized, placebo‐controlled trial of levetiracetam in central pain in multiple sclerosis

This study found no effect of the anticonvulsant levetiracetam in non‐selected patients with central pain in multiple sclerosis, but an effect in subgroups with specific pain symptoms was indicated.

A randomized placebo-controlled trial of duloxetine for central pain in multiple sclerosis.

This study suggests that duloxetine has a direct pain-relieving effect in MS, and among patients who completed 6 weeks of treatment, there were significant reductions in average and worst daily pain scores with dulOxetine compared to placebo.

Efficacy of dronabinol as an adjuvant treatment for chronic pain patients on opioid therapy.

Smoked Medicinal Cannabis for Neuropathic Pain in HIV: A Randomized, Crossover Clinical Trial

Smoked cannabis was generally well tolerated and effective when added to concomitant analgesic therapy in patients with medically refractory pain due to HIV DSPN.

Psychopathological and Cognitive Effects of Therapeutic Cannabinoids in Multiple Sclerosis: A Double-Blind, Placebo Controlled, Crossover Study

Cannabinoid treatment did not induce psychopathology and did not impair cognition in cannabis-naïve patients with MS, but the positive correlation between blood levels of &Dgr;-9-tetrahydrocannabinol and psychopathological scores suggests that at dosages higher than those used in therapeutic settings, interpersonal sensitivity, aggressiveness, and paranoiac features might arise.

Smoked cannabis for chronic neuropathic pain: a randomized controlled trial

A single inhalation of 25 mg of 9.4% tetrahydrocannabinol herbal cannabis three times daily for five days reduced the intensity of pain, improved sleep and was well tolerated, and no differences in mood or quality of life were found.

Are cannabinoids an effective and safe treatment option in the management of pain? A qualitative systematic review

Cannabinoids are no more effective than codeine in controlling pain and have depressant effects on the central nervous system that limit their use, and in acute postoperative pain they should not be used.

Administration of a single intramuscular dose of 1.5, 2.0, or 3.0 mg levonantradol or placebo to 56 patients with moderate to severe postoperative or trauma pain showed significant analgesic effects as compared to placebo, however, no significant dose response was observed.
