Application device for THC:CBD oromucosal spray in the management of resistant spasticity: pre-production testing.

 Publication Cover“Patients with multiple sclerosis spasticity (MSS) and upper limb/hand impairment who are taking 9-delta-tetrahydrocannabinol:cannabidiol (THC:CBD) oromucosal spray (Sativex®) may have difficulty self-administering their medication, possibly limiting adherence and treatment effectiveness.

A Class I EU device is available to support administration of THC:CBD spray. Pre-production testing was undertaken in a patient sample.

Results: Fifteen patients participated. Mean treatment time with THC:CBD spray was 4 (range: 0.1-6.1) years. 87% of participants ‘always’, ‘often’ or ‘sometimes’ had hand impairment, and 53% reported difficulty administering THC:CBD spray. Participants reported better application using the device (73%), with less strength required (54%). Most participants (93%) considered the instruction leaflet to be clear and many (66%) expressed interest in using the device. Most HCPs (93%) did not foresee any difficulties in use of the device.

Conclusion: The proposed adherence device was useful to address self-application difficulties with THC:CBD spray in our sample. Providing the device to MSS patients with upper limb/hand spasticity impairment may restore autonomy and support adherence to THC:CBD spray.”
