Background: In Italy, all prescriptions for THC:CBD oromucosal spray for treatment of multiple sclerosis (MS) spasticity are linked to the official Agenzia Italiana del Farmaco (AIFA) web-based registry, which tracks the effectiveness and tolerability of medications in a prospective and observational manner. Methods: AIFA e-registry data for THC: CBD oromucosal spray collected between January 2014 and February 2015 for 1,534 patients from 30 large Italian specialized MS centres were compiled. Patients had a long disease history (17.6 +/- 8.6 years) and significant impairment (mean Expanded Disability Status Scale score 6.4 +/- 1.2). MS spasticity was evaluated using the 0-10 numerical rating scale (NRS). Results: After the first month titration and trial period, 61.9% of patients achieved sufficient improvement in spasticity (>= 20% NRS) to qualify for continued treatment. After 6 months, clinically meaningful >= 30% NRS improvement was recorded in 40.2% of patients continuing with treatment. Spasticity-associated symptoms such as cramps and nocturnal spasms improved in most responding patients. Mean reported doses of THC: CBD oromucosal spray (6.2-6.7 sprays/day) were lower than those reported in clinical trials. Adverse events (mainly mild to moderate) were reported by 15% of patients; no new safety concerns beyond the approved label were identified. Conclusion: The results of the AIFA e-registry analysis align with those of other THC:CBD observational projects and reaffirm the characteristics of this therapeutic option in the management of treatment-resistant MS spasticity, a frequently overlooked symptom.

Abstract
Background: In Italy, all prescriptions for THC:CBD oromucosal spray for treatment of multiple sclerosis (MS) spasticity are linked to the official Agenzia Italiana del Farmaco (AIFA) web-based registry, which tracks the effectiveness and tolerability of medications in a prospective and observational manner.

Patients had a long disease history (17.6 +/- 8.6 years) and significant impairment (mean Expanded Disability Status Scale score 6.4 +/- 1.2).
