E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of the cannabinoids THC, CBD and a combination of CBD/THC on central neuropathic pain and spasticity in patients with multiple sclerosis and in patients with spinal cord injury |
At undersøge effekten af medicinsk cannabis på neuropatiske smerter og spasticitet hos hhv. patienter med MS og patienter med rygmarvsskade. Vi ønsker desuden at undersøge forskelle i effekten af THC, CBD og kombinationen af CBD og THC. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the efficacy of the cannabinoids THC, CBD and a combination of CBD/THC on the quality of life, cognition, stress, sleep, ataxia, and to explore the side effects. We also want to study the Pharmacodynamic and pharmacokinetic of the study medications.
|
Som sekundære effektparametre ønsker vi at undersøge effekten på livskvalitet, kognitive funktioner, stress, søvn, ataxi (ved MS) og bivirkninger ved de enkelte præparater. Vi ønsker også at undersøge farmakodynamik og farmakokinetik mhp. at opnå mere viden om blodkoncentration (terapeutisk niveau), virkningsvarighed og udskillelse ved specifik dosis.
