“Clinical trials demonstrate the efficacy and tolerability of an intervention under experimental conditions, but information on use under daily practice conditions is required to confirm the effectiveness and safety of new management options.

Clinical outcomes for THC:CBD oromucosal spray (Sativex®) in patients with treatment-resistant MS spasticity have been collected in post-marketing safety registries from the UK and Germany, a safety study from Spain and two observational studies from Germany, including one investigating its effects on driving ability.

Collectively, findings from daily practice support the long-term effectiveness and safety of THC:CBD oromucosal spray.

There was no evidence of abuse/misuse or other adverse events of special interest with a cannabis-based medicine and no impairment of driving ability.

Observational data and real world experience reinforce the efficacy and safety of THC:CBD oromucosal spray as reported in phase III clinical trials.”
