Clinical Trial Summary

The aim of the study is to evaluate the effectiveness of an aqueous solution containing CBD and CBN in the management of Facial Pain and Headache of Muscular Origin. A randomized (block randomization), double-blind, two-arm controlled trial will involve 42 adult patients diagnosed with Facial Pain and Headache of Muscular Origin which is lasting more than 3 months on the basis of clinical examination. Qualified study participants will be randomly assigned to two groups. The studied group will receive tan aqueous solution containing CBD and CBN, to drink at home in the dose determined by the attending physician, while the control group will receive an aqueous solution of placebo, to drink at home in the dose determined by the attending physician during this time. Each subject will be tested on the qualification day (D0), on 20 days after D0 (D20), and then 40 (D40) and 60 (D60) days after the qualification day using electromyography (EMG), pressure pain threshold test (PPT), clinical examination and surveys.

Description:

Background: Orofacial pain is a common occurrence. According to available scientific research, it occurs in up to 16 to 25% of the human population. In its chronic form, orofacial pain can lead to reduced sleep quality, reduced life satisfaction, and psychoemotional disorders, including depressive disorders. A popular tendency among patients suffering from chronic orofacial pain is the abuse of non-steroidal anti-inflammatory drugs, which in most cases show low, short-term and disproportionate to side effects effectiveness. There are scientific reports suggesting that substances such as cannabidiol (CBD) and cannabinol (CBN) may be effective in the treatment of chronic nociceptive and neuropathic pain. However, studies on the effectiveness of these substances in alleviating muscular orofacial pain are clearly lacking Aim: The aim of the study is to evaluate the effectiveness of an aqueous solution containing CBD and CBN in the management of Facial Pain and Headache of Muscular Origin Material and methods: A randomized (block randomization), double-blind, two-arm controlled trial will involve 42 adult patients diagnosed with Facial Pain and Headache of Muscular Origin which is lasting more than 3 months on the basis of clinical examination.
