Therapy With Paravertebral Oxygen-ozone Injections and Topical Cannabidiol and β-Caryophyllene Patch in Neck Pain

Therapy With Paravertebral Oxygen-ozone Injections and Topical Cannabidiol and β-Caryophyllene Patch in Neck Pain

Effectiveness of a Combined Therapy With Paravertebral Oxygen-ozone Injections and Topical Patch Containing Cannabidiol and β-Caryophyllene for Treatment of Neck Pain: a Prospective, Randomized, Controlled Trial.

The aim of this study is to compare the effectiveness of combined treatment with paravertebral oxygen-ozone injections and topical patches containing Cannabidiol and β-Caryophyllene in patients with neck pain by evaluating the following aspects: Reduction of pain Reduction of disability associated with neck pain

Neck pain is a significant public health burden worldwide, with a prevalence of 2,696.5 per 100,000, and a major cause of disability, responsible for 2.56% of all years lived with disability. Many potential therapeutic interventions are available for the treatment of neck pain, including conservative therapies, minimally invasive procedures and open surgery. In particular, oxygen-ozone percutaneous injections have been tested and have proven to be well tolerated with good clinical results. Patch cutaneous formulated with cannabidiol and β-carophyllene (Levotens®) has proven to have muscle relaxant and anti-inflammatory effects in an animal models: The tests used allow to evaluate motor performance with reference to motor coordination skills (pole test), exploration (open field test) and resistance to continuous and accelerated movement (rotarod test). These motor skills are impaired in a pain associated inflammatory response condition such as that induced by LPS (lipopolysaccharide). The CBD and BCP-based Levotens® patch placed in the area where the inflammatory stimulus is administered allows the recovery of motor function in the three types of behaviors studied. Previous data available demonstrate a muscle relaxant action of CBD applied topically through a patch in patients suffering from TMD. This is a randomized, controlled, prospective evaluation comparing combined treatment with paravertebral oxygen-ozone injections and topical patches containing Cannabidiol and β-Caryophyllene with only OOT. The maximum study duration for each subject will be 6 months. A total of 52 patients will be enrolled. These patients will meet specific inclusion and exclusion criteria but can be generally characterized as patients with neck pain who have been unable to achieve satisfactory pain relief with previous conservative treatments The primary study objective is to determine whether combining Levotens® Patch with OOT could lead to better early pain control than OOT alone. The primary study endpoint is to establish the improvement in NRS Pain at 14 days from the start of treatment. Secondary objectives of this study are: Improvement in NRS pain at 1, 2, 4, 12, 36 weeks, Improvement in NDI at 1, 2, 4, 12, 36 weeks.

The patients will undergo 8 session of oxygen-ozone therapy, 2 per week. In each session 10 cc of a gaseous mixture of oxygen-ozone (at a concentration of 10 μg of ozone per ml of oxygen) will be injected with 6 paravertebral injections. For the fisrt 2 weeks of oxygen-ozone therapy patients will be asked to apply patches with local action based on Cannabidiol and ß-Caryophyllene for 8-24 hours/day for 5 days/week.

Cannabidiol with its decongestant activity has a soothing action in the area of application, thanks to the association with B-caryophyllene which assists its activity

Ozone (O3) is a molecule consisting of 3 atoms of oxygen in a dynamically unstable structure. O3 has the capacity to modulate inflammation. O3 when in contact with human fluids and tissues rapidly reacts, generating many reactive oxygen species, as hydrogen peroxide (H2O2), superoxide ion, and hydroxyl radical (OH-). It is suggested that through moderate oxidative stress generated by these reactive byproducts, O2O3 might produce positive effects in several pathologies, including musculoskeletal affections. Moreover, O2/O3 may directly regulate prostaglandins (PGS) and bradykinin, and suppress several proinflammatory mediators, such as IL-6, IL-8 and TNF-α
