Definitions

  • the acute phase is the early, non-specific phase and is characterized by local vasodilation, increased capillary permeability, the accumulation of fluid and blood proteins in the interstitial spaces, the migration of neutrophils out of the capillaries, and the release of inflammatory mediators. Pain is produced by all these pro-inflammatory agents, that also leads to hyperalgesia through the activation of the corresponding receptors, which are expressed by nonreceptive terminals.
  • the inflammatory process progressed toward subacute/chronic inflammation, which is characterized by immunopathological changes such as the infiltration of inflammatory cells, the overexpression of pro-inflammatory genes, the dysregulation of cellular signaling and the loss of barrier function 1 .
  • the chronic pathological pain state including neuropathic pain, is a leading health problem worldwide as it endures beyond the resolution of the pain source and can deeply impact quality of life 2 .
  • tissue injury and/or inflammation can induce reversible adaptive changes in the sensory nervous system leading to protective sensitization
  • changes in sensitivity become persistent or chronic in neuropathic pain.
  • the nervous system peripheral of central, is injured in neuropathic pain. It is characterized by pain in the absence of a noxious stimulus and may be spontaneous in its temporal characteristics or be evoked by sensory stimuli.
  • Arthritis is a classic example of chronic pain inflammation, as are various diseases and conditions, including, for example, cardiovascular and neurodegenerative diseases, diabetes, cancer, and asthma.
  • Synthetic anti-inflammatory compounds are one of the general ways to control chronic inflammation and pain.
  • There are several common side effects associated with these synthetic anti-inflammatory drug products such as gastric irritation and ulceration, renal and hepatic failure, hemolytic anemia, asthma exacerbation.
  • Increasing amount of evidence demonstrates that the endocannabinoid system actively participates in the pathophysiology of osteoarthritis-associated joint pain.
  • preclinical and clinical data support the potentially effective anti inflammatory properties of endocannabinoids agonist that target CB2 (Cannabinoid receptor 2) receptors 3 .
  • Cannabis (marijuana) is a schedule-I drug in USA.
  • Cannabis is a flowering plant which contains more than 400 phytonutrient (micronutrient). More than 100 different types of terpenoids, essential oils, antioxidants and cannabinoids have been extracted from the plant. From all of the phytochemicals, only tetrahydrocannabinol (THC) showed significant psychoactive effect. A number of research papers have been published on THC due to its psychoactive and therapeutic effects.
  • THC cannabidiol
  • CBD cannbinol
  • CBC cannabichromene
  • CBG cannabigerol
  • THCV tetrahydrocannbivarin
  • delta 9- tetrahydrocannbinol delta 9- tetrahydrocannbinol
  • cannabis and its derivatives can be used for the treatment of pain, type-2 related metabolic disorder, decrease intraocular pressure, Dravet syndrome, Lennox-Gastaut Syndrome (LGS), epilepsy, nausea, pain and wasting associated with AIDS, arthritis and rheumatism, migraines, muscle spasticity associated with multiple sclerosis and paralysis, alcohol and narcotics withdrawal, stress and depression, asthma, fibromyalgia, inflammatory pain, and pain and/or inflammation associated with chemotherapy, act as an antimicrobial.
  • FDA approved Marinol and Syndros contains delta 9-THC, which currently used in treatment of nausea, vomiting, and anorexia associated with chemotherapy treatments.
  • Cannabidiol is an orally effective treatment for pain and inflammation.
  • TSC Tuberous Sclerosis Complex
  • Dravet Syndrome Dravet Syndrome
  • Lennox-Gastaut Syndrome Cannabidiol is an orally effective treatment for pain and inflammation.
  • Cannabidiol is an orally effective therapeutic agent in rat chronic inflammatory and neuropathic pain. European Journal of Pharmacology. Volume 556, Issues 1-3, 5 February 2007, Pages 75-83).
  • cannabinoids have been identified from cannabis Sativa. These compounds are similar to the endogenous cannabinoid group that consists of long chain polyunsaturated fatty acids 4 .
  • the endocannabinoid system is a one of the important endogenous lipids signaling pathway, which consists of cannabinoid receptors, the endogenous ligands of cannabinoid receptors (endocannabinoids) and the enzymes that regulate the biosynthesis and inactivation of endocannabinoids.
  • the lipid signaling system is involved in many important physiological functions in the central and peripheral nervous system and in the endocrine and immune system. These receptors are from family of Guanosine Binding Protein-Coupled Receptors, are widely expressed and distinguished by their specific function, localization and signaling mechanisms 5 ⁇ 3 .
  • Cannabinoid receptor 1 (CB1), inhibits adenylate cyclase and reduce cAMP levels and protein kinase A (PKA) activity, resulting in the activation of the A-type potassium channels and decrease cellular potassium levels.
  • PKA protein kinase A
  • This receptor mainly found in adipose tissue, the GI tract, the spinal cord, the adrenal and thyroid glands, liver, reproductive organ and immune cells 6 .
  • Cannabidiol a major non-psychoactive phytocannabinoid has little affinity for CB1 and CB2, and act as a partial antagonist CB1 and as a weak inverse CB2 agonist 7 .
  • CB1 and CB2 receptor agonists demonstrate anti-nociceptive activity, whether used singly or in combination, with CB2 activity believed to affect microglial cells and thereby reduce neuro-inflammatory mechanisms 12 ⁇ 13 .
  • the CB2 receptor is thought to be particularly important in central neuronal pain circuits, as agonist activity induces dopamine release in mid-brain areas, contributing to descending pain control and the placebo effect 14 .
  • Inflammatory effects can either be modulated via the upregulation of cannabinoid receptor activity or increased production of endocannabinoids, providing an attenuation in joint destruction in preclinical models of inflammatory arthritis that mimic human rheumatoid arthritis 8 10 .
  • CB1 and CB2 receptors, proteins and endocannabinoids are found in the human synovial tissue of patients with both rheumatoid arthritis and osteoarthritis 15 .
  • transdermal CBD delivery has therapeutic potential for the relief of arthritic pain-related behavior and to exert an anti-inflammatory effect without any evident of psychoactive effect using complete Freund’s adjuvant-induced monoarthritic knee join mode. Result also showed that a dose of 6.2 mg/day reduce knee-joint swelling and that increase the dose of 62 mg/day failed to yield any additional improvement 16 .
  • compositions and methods of the disclosure are directed to drug delivery directly to the systemic circulation via application to the skin, and thus the compositions and methods of the disclosure overcome these problems because the active agent avoids being metabolized by the liver after absorption, and also gastrointestinal irritation is avoided.
  • transdermal route can be avoided using transdermal route. Furthermore, the peak and valley in the plasma concentration due to oral administration can be avoided by delivering the drug molecule constantly at predetermined input rate using transdermal dosage forms.
  • US 6328992 provides examples for reservoir and adhesive matrix patches. All these examples contain mixture of cannabinoids (such as delta- 8-THC, delta-9-THC, cannabidiol and cannabinol) instead of cannabidiol only.
  • cannabinoids such as delta- 8-THC, delta-9-THC, cannabidiol and cannabinol
  • the THC is an psychoactive agent and addictive substance, so, the utility of this is limited.
  • There is a need for an improved drug delivery system of cannabidiol which can overcome the drawbacks associated with oral routes.
  • Transdermal delivery of cannabidiol, the free base thereof, salts thereof, isomers thereof, amorphous forms thereof, crystalline forms thereof, co crystalline forms thereof, prodrugs thereof, analogs thereof, derivatives thereof, synthetic forms thereof, biosynthetic forms thereof, active metabolites thereof, alone or in combinations thereof can address the challenges associated with oral drug delivery.
  • the current disclosure addresses all the above drawbacks and provide patent which can have a real world utility.
  • the current disclosure provides for the use of a synthetic version of cannabidiol which is manufactured in more controlled environment than the botanical source of the same.
  • the synthetic version of cannabidiol can provide more permeability as compared to adulterated version of it.
  • transdermal matrix patches which can deliver synthetic cannabidiol for 1 day, and/or 2-days, and/or 3-days, and/or 4 days, and/or 5 days, and/or 6 days, and/or 7 days, and/or up to 15 days.
  • transdermal patch or transdermal composition is applied topically to the skin surface.
  • a transdermal patch or transdermal composition drug is continuously released and delivered through the intact skin (via transcellular, intercellular and transappendageal routes) to achieve systemic effect. Therefore, once applied transdermal composition or transdermal patch can deliver drug into systemic circulation throughout the day or even for more than one day depending on the duration of its application which can be even up to a week.
  • Transdermal delivery can reduce the dosing frequency of cannabidiol, the free base thereof, salts thereof, isomers thereof, amorphous forms thereof, crystalline forms thereof, co crystalline forms thereof, prodrugs thereof, analogs thereof, derivatives thereof, synthetic forms thereof, biosynthetic forms thereof, active metabolites thereof, alone or in combinations thereof.

  • the duration of topical application can be once in a day, once in two days, once in three days, once in four days, once in five days, once in a week. Therefore, transdermal delivery can overcome the multiple dose regimen of oral delivery by reducing the dosing frequency.
  • transdermal drug delivery the drug is delivered slowly and continuously throughout the duration of topical application hence there are no peaks and troughs in drug plasma concentration which are associated with multiple dose administration in a day. Therefore, by transdermal delivery of cannabidiol, the free base thereof, salts thereof, isomers thereof, amorphous forms thereof, crystalline forms thereof, co crystalline forms thereof, prodrugs thereof, analogs thereof, derivatives thereof, synthetic forms thereof, biosynthetic forms thereof, active metabolites thereof, alone or in combinations thereof, patients can have the therapeutic effect of the drug for extended period of time without drastic changes in drug plasma concentration.
  • compositions of the disclosure overcome these problems because in transdermal delivery, active agent is delivered directly into systemic circulation through the skin, and it escapes the first pass hepatic metabolism therefore to achieve the desired therapeutic activity less drug is required, resulting into less adverse effects or side effects.
  • Cannabinol has high lipid solubility and after oral administration undergoes hepatic first pass metabolism, therefore of the administered dose only 10% - 20% reaches systemic circulation, thus as compared to oral dose, transdermal delivery a small dose of cannabidiol can give the desired therapeutic effects at a lower dose than oral.
  • Transdermal delivery is easy, noninvasive and convenient. Administration of a transdermal patch or transdermal composition does not require medical supervision as patients can topically apply the transdermal patch or transdermal composition themselves.
  • transdermal delivery can reduce the dosing frequency of cannabidiol, the free base thereof, salts thereof, isomers thereof, amorphous forms thereof, crystalline forms thereof, co crystalline forms thereof, prodrugs thereof, analogs thereof, derivatives thereof, synthetic forms thereof, biosynthetic forms thereof, active metabolites thereof, alone or in combinations thereof.
  • dosing frequency can be once in a day, once in two days, once in three days, once in four days, once in five days, once in six days, once in a week.

  • the prepared transdermal formulations were then subjected to a flux measurement test as follows. Human cadaver skin, stored at -80°C, was thawed at room temperature in phosphate buffered saline (PBS), and visually inspected for defects before using in the study. Transdermal flux was then measured using standard Franz diffusion cells composed of a cylindrical donor compartment and a separate water jacketed cylindrical receptor compartment with the volume of 13 mL. The human cadaver skin was clamped between the two compartments with the dermis side facing toward the receptor compartment. The donor compartment was filled with the transdermal CBD formulations prepared as described above. The receptor compartment was filled with receptor medium, held at constant temperature, and constantly stirred to collect the CBD as it diffuses through the skin and into receptor compartment.
