“Spasticity, perceived by patients as muscle rigidity and spasms, is a common symptom in multiple sclerosis (MS). It is associated with functional impairment that can exacerbate other MS symptoms and reduce quality of life.

Pharmacological treatment options are limited and frequently ineffective. Treatment adherence is a key issue to address in these patients.

The efficacy and safety of 9-delta-tetrahydrocannabinol:cannabidiol (THC:CBD) oromucosal spray for treatment of MS spasticity were demonstrated in four Phase III trials.

Observational studies and registry data subsequently confirmed the effectiveness and tolerability of THC:CBD oromucosal spray under everyday practice conditions.

Among patients who respond to treatment, THC:CBD oromucosal spray has been shown to produce positive improvements in gait parameters and to normalize muscle fibers.”
