Definitions

  • the present invention relates to methods and compositions for treating restless legs syndrome.
  • the methods comprise the administration of a composition comprising a cannabinoid and/or a terpene to a patient in need of such treatment.
  • Restless legs syndrome is a term used to describe a neurological sensory disorder that also interferes with sleep and is thus also considered a sleep disorder. Restless legs syndrome is otherwise known as Willis-Ekbom Disease, and Wittmaack-Ekbom syndrome.
  • the clinical manifestations include the compelling, irresistible, or uncontrollable urge to move, restlessness, and abnormal, unpleasant, or uncomfortable sensations in the limbs or the skin of the feet, legs, arms, or elsewhere which include pain, aching, throbbing, pulling, itching, crawling, creeping, burning, jerking, fidgety, antsy, electrical, pins and needles, buzzing, and twitching.
  • the movements may be persistent, repetitive, periodic, or intermittent with symptoms in remission for periods of time.
  • Clinical manifestations appear mainly in the evening or nighttime, sometimes peaking between the hours of 12: 00 AM to 4:00 AM. They can also manifest during periods of relaxation, rest, inactivity, or by lying or sitting down for a period of time.
  • RLS is believed to be related to dysfunction in the basal ganglia section of the brain that controls movement and that uses dopamine. This dysfunction is thought to be similar to the dopamine dysfunction of Parkinson's disease.
  • factors or conditions that are linked to RLS which include iron deficiency, pregnancy, certain medications such as anticonvulsants, antidepressants, beta-blockers, antipsychotics, certain substances such as alcohol, caffeine, cigarettes, neuropathy, venous disorders, renal disease and failure, sleep disorders, genetic inheritance, fibromyalgia, vitamin and mineral deficiencies, amyloidosis, hyper or hypothyroidism, Lyme disease, arthritis, diabetes mellitus, Periodic Limb Movement Disorder (PLMD) and Parkinson's disease.
  • certain medications such as anticonvulsants, antidepressants, beta-blockers, antipsychotics, certain substances such as alcohol, caffeine, cigarettes, neuropathy, venous disorders, renal disease and failure, sleep disorders, genetic inheritance, fibromyalgia, vitamin and mineral deficiencies, amyloido
  • RLS is described as primary restless legs syndrome or secondary restless legs syndrome.
  • Primary RLS is restless legs syndrome beginning before the age of 40. It is sometimes associated with genetic inheritance.
  • Secondary RLS is restless legs syndrome beginning after the age of 40, and is usually associated with the use of medications or other substances.
  • RLS Treatment options include treating the associated factors or conditions and physical measures, but most treatment options are futile resulting in progressively worsening clinical manifestations and which may eventually lead to insomnia. Lack of sleep due to RLS contributes to an impairment in life quality and an increase in depressive disorders, anxiety, and the occurrence of panic attacks. Patients with RLS sometimes use treatment options that include dopamine agonists, opiates, or anticonvulsants or a combination thereof, however most patients halt treatment due to the poor efficacy or harmful side effects.
  • the present invention accomplishes the above objectives and others by providing a method of treating RLS comprising the administration of a composition comprising at least one cannabinoid, at least one terpene, or a combination of at least one cannabinoid and at least one terpene.
  • Embodiments of the present invention are specifically directed to the treatment of primary RLS and secondary RLS.
  • the administration may be topical, oral, nasal, inhalation or a combination thereof.
  • composition is administered topically, it may be applied to a patient's skin in the form of a patch, gel, cream, paste, lotion, ointment, salve, serum, spray, aerosol, mousse or foam.
  • composition may be provided in a solid or liquid form that may be swallowed or held in the oral cavity.
  • the solid oral form may be a tablet, capsule, powder, or sachet, and may be administered in the solid form or dispersed or mixed with a food such as applesauce or oatmeal, or water, for easier swallowing.
  • the liquid oral form may be a solution, suspension or syrup that may be swallowed or applied to the oral cavity as a spray, mist, aerosol or drops.
