Benefits of a Cannabidiolic Acid Topical Cream for the Treatment of Restless Leg Syndrome

Restless Leg Syndrome (RLS) is multifactorial disease state with many different potential pathophysiological mechanisms, which includes dysfunctions from the cerebral cortex and spinal cord to mechanosensitive channels at the musculoskeletal periphery.1 Most therapeutic agents' effectiveness focuses on the CNS (e.g., dopaminergic drugs) or Renshaw cells. To our knowledge, therapeutic agents that are focused on the periphery were not very effective.

This technology focuses on the peripheral musculoskeletal component of the disease and is directed at treatment modalities that correct the dysfunction of mechanosensitive channels. By combining what is known about cannabinoids activity at the transient receptor potential channel of ankyrin 1 (TRPA1)2 and the role TRPA1 plays in regulating the shape and rigidity of the surrounding membrane structure at the Piezo channels3, an effective therapy at the site of discomfort should emerge. Moreover, the lessening of membrane tension is imparted by molecules that readily penetrate the membrane4, which Chylobinoid, the topical active ingredient, is uniquely designed to do.
