Background:
Tetrahydrocannabinol:cannabidiol (THC:CBD) oromucosal spray (Sativex®) is an add-on therapy for moderate-to-severe multiple sclerosis (MS)-related drug-resistant spasticity (MSS).
Aim:
The MOVE-2 EU study collected data from everyday clinical practice concerning the effectiveness and tolerability of THC:CBD.
Methods:
This was an observational, prospective, multicentre, non-interventional study. Patients with resistant MSS prescribed add-on THC:CBD oromucosal spray according to approved labelling, were followed for 3 months. After 1 month, only responders (≥20% improvement in spasticity) continued treatment. The main endpoints were the evolution of MSS and associated symptoms, quality of life (QoL) and tolerability.
Results:
Four hundred and thirty three patients (55% female) were recruited (98% in Italy). The mean duration of MSS was 7.4 years and baclofen was used by 78.1% of participants. Three hundred and forty nine participants continued with THC:CBD oromucosal spray after 1 month, and 281 after 3 months. THC:CBD mean dosage was 6 sprays/day. MSS scores and spasticity-related symptoms (spasms, fatigue, pain, sleep quality and bladder dysfunction) were significantly improved by THC:CBD at 3 months, as were activities of daily living, and QoL (EQ-5D VAS). Adverse events, none of which were severe or serious, were reported by 10.4% of patients.
Conclusions:
In everyday clinical practice, THC:CBD oromucosal spray provided symptomatic relief of MSS and related troublesome symptoms.

Centrally Acting Muscle Relaxants: Therapeutic Uses
Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...
Spasmolytic Agents: Chemical Classification
A major class of centrally acting spasmolytics is the α2-agonist, such as tizanidine. These drugs bind to α2-adrenoceptors, inhibiting the release of the excitatory neurotransmitter glutamate. They also...
