DETAILED DESCRIPTION

[0019] Various embodiments are described hereinafter. It should be noted that the specific embodiments are not intended as an exhaustive description or as a limitation to the broader aspects discussed herein. One aspect described in conjunction with a particular embodiment is not necessarily limited to that embodiment and can be practiced with any other embodiment(s).

[0020] The use of the terms “a” and “an” and “the” and similar referents in the context of describing the elements (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate the embodiments and does not pose a limitation on the scope of the claims unless otherwise stated. No language in the specification should be construed as indicating any non-claimed element as essential.

[0021] Unless otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in this specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by embodiments of the present disclosure. As used herein, “about” may be understood by persons of ordinary skill in the art and can vary to some extent depending upon the context in which it is used. If there are uses of the term which are not clear to persons of ordinary skill in the art, given the context in which it is used, “about” may mean up to plus or minus 10% of the particular term.

[0022] The terms “%”, “% by weight”, “weight %” and “wt%” are all intended to mean unless otherwise stated, percents by weight based upon a total weight of 100% end composition weight. Thus 10% by weight means that the component constitutes 10 wt. parts out of every 100 wt. parts of total composition.

[0023] The term “pharmaceutically acceptable” means that which is useful in preparing a pharmaceutical composition that is generally non-toxic and is not biologically undesirable and includes that which is acceptable for veterinary use and/or human pharmaceutical use.

[0024] The term “topically acceptable” means the compound, substance or device may be administered to or onto the surface of a patient, including the skin or other accessible tissues, without substantial harmful effects to the body part and/or its surfaces.

[0025] The terms "treating" and “effective amount”, as used herein, unless otherwise indicated, means reversing, alleviating, inhibiting the progress of, or preventing the disorder or condition to which such term applies, or one or more symptoms of such disorder or condition. The term "treatment", as used herein, unless otherwise indicated, refers to the act of treating as "treating" is defined immediately above. The term “treating” also includes adjuvant and neo-adjuvant treatment of a subject.

[0026] All of the embodiments included here are with the proviso that the sum of ingredients in the exemplary compositions does not exceed 100%.

[0027] The delivery systems, patches, vehicles and devices of the present disclosure are also useful in the fields of human medicine for the administration of active agents to people (i.e., human patients) and veterinary medicine for the administration of active agents to pets and farm animals. [0028] The aspects of the present disclosure relate to transdermal delivery systems, patches, vehicles and devices used to relieve pain (i.e., analgesics) and/or inflammation, methods of making such transdermal delivery systems, patches, vehicles and devices and methods of using such transdermal delivery systems, patches, vehicles and devices including topically applied (e.g., to skin or another body part) such transdermal delivery systems, patches, vehicles and devices including pharmaceutical transdermal delivery systems, patches, vehicles and devices, including analgesic and/or anti-inflammatory pharmaceutical compositions for the treatment of pain and/or inflammation, that contain a pharmaceutically effective amount of a pharmaceutically acceptable and effective cannabinoid and menthol. Such transdermal delivery systems, patches, vehicles and devices of the present disclosure can include, for example, gel material (e.g., hydrogel material) alone or in combination with a backing material as well as iontophoretic delivery systems, patches, vehicles and devices that include gel material (e.g., hydrogel material including a hydrogel reservoir) with additional electrical components and use electrical energy to aid in the penetration and administration of active agents contained therein.

[0029] The combination of cannabinoid and menthol into a single therapeutic composition, for example, a transdermal delivery system, patch, vehicle or device can provide improved and better focused delivery of the actives to a patient than separately applying the cannabinoid and menthol separately (to different areas of the body or layered one on top of another) without the hydrous or other hydrogel vehicles (e.g., hydrogel reservoir).

[0030] Transdermal delivery systems, patches, vehicles and devices, such as, for example, embodiments of the present disclosure, include transdermal delivery systems, patches, vehicles and devices in a desired size, shape and weight which, in the ordinary course of usage, can be placed topically on a body part (e.g., arm, leg, knee, torso, head, neck, foot as well as those parts that make-up them) for purposes of local and/or systemic administration of particular therapeutic agents for a time sufficient to be effective for purposes of therapeutic activity to the body part and tissues thereof or other tissues remote from the application site in order to provide relief from the malady being suffered (e.g., pain relief though an analgesic and/or anesthetic effect) including a malady of the body part (e.g., pain and/or inflammation) to which the transdermal delivery systems, patches, vehicles and devices of the present disclosure can be directly applied for relief. After being present in contact with the body part for a time sufficient to be effective for purposes of therapeutic activity, they can be removed from the body part. Such application to the body part includes placing the transdermal delivery systems, patches, vehicles and devices in contact with the skin covering the body part.

[0031] Embodiments of the present disclosure may be delivered for local or systemic administration to a body part of a person to be treated with the embodiment, for example, a body or skin surface thereof by placing an embodiment of the present disclosure on a body part or skin surface thereof, for example, a knee, leg, back of hand, arm, lower back, upper back, shoulder and forehead, in active agent-transmitting relation thereto, the active agents being cannabinoid, for example, a phytocannabinoid or full spectrum hemp oil, and menthol. Alternatively, an embodiment of the present disclosure may be incorporated into a transdermal delivery system, patch, vehicle or device, such as a unit dose delivery transdermal delivery system, patch, vehicle or device.

[0032] Non-limiting examples of injuries or other physical diseases or conditions causing pain and/or inflammation for which embodiments of the present disclosure can be used to reduce or lessen the pain and/or inflammation can include arthritis conditions (e.g., osteo, rheumatoid, psoriatic, fibromyalgia, etc.), head pain (e.g., concussion, head ache, migraine), orthopedic injuries or conditions (e.g., bone fracture or break; dislocated joint or bone; torn, stressed or strained ligament or tendon; bruising or trauma to tissue; back or spinal pain or herniated disc; tendonitis; gout, bursitis), muscles aches and pains (e.g., from stress and physical exertion) and post-surgery recovery (e.g., recovery from orthopedic surgery to repair a broken bone, back condition such as herniated disk or torn ligament, orthoscopic surgery).

[0033] Embodiments of the present disclosure include treated hydrogel material of the present disclosure including cannabinoids and menthol alone, with a backing material or as iontophoretic delivery systems, patches, vehicles and devices that include gel material (e.g., hydrogel material also referred to herein as a hydrogel reservoir) with additional electrical components of the present disclosure.

[0034] Cannabinoids included in embodiments of the present disclosure are an active agent and a class of chemical compounds that can be derived from plants (phytocannabinoids) or synthetically produced. Cannabinoids can have local and systemic analgesic, pain relieving, pain treating and anti-inflammatory therapeutic properties. Cannabinoids may also have other medical benefits and/or be useful in treating other medical conditions including, for example, reduction of anxiety and depression, reduction of symptoms like nausea, vomiting and pain related to cancer treatments, reduction of acne, protection of the neural system and benefits for the heart and circulatory system by the lowering of blood pressure. Cannabinoids can also have therapeutic value as a nutrient and can be included in composition and method embodiments of the present disclosure in an effective amount to perform that function.

[0035] Examples of phytocannabinoids include Cannabidiol (CBD) including, for example, CBD oil, Cannabinol (CBN), Cannabigerol (CBG) and tetrahydrocannabinol (THC), the latter being a known psychotropic compound and the first two being nonpsychotropic. Cannabis and hemp plants can exhibit wide variation in the quantity and type of cannabinoids they produce. Selective breeding of the plants can be used to control the genetics of plants and modify the cannabinoids produced by the plant. For example, there are strains that are used as fiber (commonly called hemp) and, as a result, have been bred such that they are low in psychoactive chemicals like THC. Such strains (e.g., hemp) used in medicine are, for example, often bred for high CBD content and have minimal levels of THC (less than 0.3%). Some embodiments of the present disclosure include a cannabinoid component with less than 0.3% THC and may also include embodiments that do not include controlled substances as defined in the Controlled Substances Act. Examples of topical, transdermal and/or pharmaceutically effective cannabinoids include CBD (for example, full spectrum hemp oil). Cannabinoid, including, for example, phytocannabinoids including CBD, can be in an amount of about 25 wt% to about 65 wt %, about 35 wt% (based on 25% CBD cone, in CBD or hemp oil). CBD can be in an amount of about 25 wt% to about 65 wt %, about 35 wt% (wt % based on the hydrogel weight). Full spectrum CBD or hemp oil can be in an amount of about 25 wt% to about 65 wt%, about 35 wt% (based on 25% CBD cone, in the CBD or hemp oil) (wt% based on the hydrogel weight). Unit dosage formulations of the embodiments of the present disclosure can include cannabinoid, for example, a phytocannabinoid (including for example, CBD) in the amount of about 5.0 mg. to about 5000.00 mg. (based on 25% CBD cone, in the CBD or hemp oil). Unit dosage formulations of the embodiments of the present disclosure can include CBD in the amount of about 1 .250 mg. to about 1250.00 mg. Unit doses of full spectrum CBD or hemp oil can include an amount of about 5.0 mg. to about 5000.00 mg. (based on 25% CBD cone, in the CBD or hemp oil). Unit dosage formulations of the embodiments of the present disclosure can include cannabinoid, for example, a phytocannabinoid (including for example, CBD) or full spectrum hemp oil in the amount of about 5.0 mg./ml. to about 1000.00 mg./ml. (based on 25% CBD cone, in the hemp oil). Unit dosage formulations of the embodiments of the present disclosure can include CBD in the amount of about 1 .25 mg./ml. to about 250.00 mg./ml of the hydrogel, including a unit dose per patch or device of from about 5 mg. to about 1000 mg and a unit dose of about 5 mg., about 1000 mg or about 500 mg. Unit dosage formulations of the embodiments of the present disclosure can include full spectrum CBD oil in an amount of about 5.0 mg./ml. to about 1000.00 mg./ml (based on 25% CBD cone, in the CBD oil).

[0036] Cannabinoids, for example, CBD can have a local and/or a systemic effect and may reduce pain imparting and regulating the endocannabinoid (neurotransmitter of the nervous system) receptor activity. The subsequent body functions that may be regulated include pain, sleep, appetite and immune system response (through, at least, in part, by reducing inflammation).

[0037] For the purpose of the present disclosure, the word “cannabinoid” refers to one or more cannabinoids or cannabinoid compounds or oils or extracts from plants (for example, hemp including hemp oil and full spectrum CBD or full spectrum hemp oil) that include one or a plurality of phytocannabinoids.

[0038] Full spectrum hemp oil is oil derived from the entire hemp plant except the flower (which contains THC) and can have over 85 phytocannabinoids which can have a positive synergistic effect as compared to compositions having fewer cannabinoids. There may also be benefits to other components of it (e.g., terpenes). Such benefits and effect may include faster penetration and/or permeation of the therapeutic components thereof. Full spectrum hemp oil can include full spectrum hemp oil that has been purified to include less than the below stated amounts of one or more of the following impurities (based on the hydrogel weight):

Aflatoxins Bl, 82, G1 , G2 (fats, oils, lecithin, egg powder): <0.1 pg/kg of each of Aflatoxin B1 , Aflatoxin B2, Aflatoxin Gl and Aflatoxin G2, Sum of all positive Aflatoxins <0.4 pg/kg.

GlyphosatelAMPAiGlufosinate: <0.1 mg/kg of each of Glufosinate, Glyphosate and Aminomethylphosphonic acid (AMPA)

Mercury: <0.02 mg/kg

Arsentic: <0.03 mg/kg

Cadmium: <0.01 mg/kg

Lead: <0.05 mg/kg.

[0039] Embodiments of the present disclosure may also optionally include an effective amount of THC. Unit dosage formulations of the embodiments of the present disclosure can include THC in the amount of about 0.1 mg. to about 10 mg., about 1 mg. to about 10 mg., about 4 mg. to about 6 mg. about 5 mg. In addition to the other benefits that can be provided by other cannabinoids, THC may relieve stress and be a sleeping aid.

[0040] Menthol included in embodiments of the present disclosure (which also includes stabilized or less volatile menthol mixtures as described herein) is an active agent and an organic compound that can be made synthetically or obtained from mint oils such as corn mint and peppermint. Medicinally, it been found that menthol can have anesthetic (e.g., local) by, for example, blocking nerve signal transmission) and counterirritant properties as well as anti-inflammatory properties (e.g., systemic and local) as well as a cooling effect when administered topically to a patient. Furthermore, menthol is a vasodilator (including a topical vasodilator) that can accelerate the transport of active in the circulatory system. In general, the action of local anesthetics can restrict to the site of application and rapidly reverses upon diffusion from the site of action in the nerve. Local anesthetics can also serve an important function in providing peripheral pain relief. Topical administration of pain-relieving anesthetics can provide important advantages over systemic or local, non- topical administration. Menthol can also act as a phosphodiesterase inhibitor and calcium channel blocker (CCB). Menthol can be in an amount of about 30 wt% to about 70 wt%, about 50 wt % (wt% based on the hydrogel weight). Unit dosage formulations of the embodiments of the present disclosure can include menthol in the amount of about 0.0025 mg. to about 1000.00 mg. Unit dosage formulations of the embodiments of the present disclosure can include menthol in the amount of about 0.0025 mg./ml. to about 200 mg./ml. Unit dosage formulations of the embodiments of the present disclosure can include menthol in the amount per unit of surface area (e.g., surface areas 102 and 104 in FIG.1 , in FIG. 2A with surface areas 202 and 204 and in FIG. 2B and with surface areas 208 and 210) of about 0.0005 mg./cm ² to about 1000.00 mg./cm ² . An effective amount of menthol includes an anesthetic, pain reducing (e.g., analgesic) or anti-inflammatory effective amount of menthol. The patch or device may include about 3 wt% of menthol in a typical about 7 cm. by about 10 cm patch (wt% based on the hydrogel weight), about 210 mg per patch or device.

[0041] Menthol may be stabilized or made less volatile using methods know in the art, such as, for example, mixing it with about 0.1 wt% to about 10 wt%, about 0.5 wt% to about 5 wt% of a surfactant including edible nonionic surfactants and ionic surfactants, such as, for example, sucrose fatty acid ester, polysorbate (e.g., polysorbate 80), hydrogenated castor oil (e.g., polyoxyethylene hydrogenated castor oil), cocamidopropyl betaine, cyclodextrins, adsorbents, encapsulations, nano-emulsions etc.

[0042] The stabilized or less volatile menthol compositions can also made by mixing together (a) menthol and (b) a menthol stabilizer compound (e.g., dissolving the menthol in the menthol stabilizer compound ) in a ratio of (a) about 1 molar part menthol to (b) the amount of one or more than one of the menthol stabilizer compounds (undecylenic acid methyl ester, undecylenic acid or a salt (preferably a pharmaceutically acceptable salt) of undecylenic acid, including mixtures thereof) (i.e., one of the menthol stabilizer compounds or a mixture of more than one of the menthol stabilizer compounds) of from about 0.005 molar part to about 1.00 molar part, about 0.010 molar part to about 0.750 molar part, about 0.020 molar part to about 0.50 molar part, about 0.050 molar part to about 0.250 molar part, or about 0.10 molar part. It is believed that the menthol stabilizer compounds (e.g., undecylenic acid methyl ester and others included herein) and menthol may associate to form a menthol analog where the menthol analog’s vapor pressure becomes lower than menthol itself. As a result of having a lower vapor pressure, the menthol component of the menthol analog volatizes as a lower rate than menthol by itself. Undecylenic acid methyl ester may also act as a penetration enhancer, local anesthetic, phosphodiesterase inhibitor and calcium channel blocker (CCB).

[0043] One possible explanation for the stabilization or lessening the volatility of menthol by the compound of formula (I) may be that the menthol associates with the alkenyl side chain of the menthol stabilizer compounds may provide a molecular attraction connecting the menthol stabilizer compounds and a menthol molecule, such that more than one menthol molecule may associate with a molecule of one of the menthol stabilizer compounds.

[0044] The stabilized or less volatile menthol compositions including menthol and at least one of the menthol stabilizer compounds (e.g., undecylenic acid methyl ester and others included herein) can also be made first by dissolving menthol in a pharmaceutically acceptable suitable solvent such as, for example, as a low, medium, or long chain triglyceride. Examples of such solvents are coconut oil, olive oil, palm oil, hemp oil and castor oil. Still other acceptable solvents, such as alcohols, ethers and polyalcohols, for example, propylene glycol, butylene glycol, and polyethylene glycols (PEGs) can also be used. The desired amount of at least one of the menthol stabilizer compounds disclosed herein (e.g., undecylenic acid methyl ester and others disclosed herein) is then added to that mixture. Such compositions that include menthol, solvent and one or more than one of the menthol stabilizer compounds included herein may be made where the mixture of the these ingredients includes a molar ratio of about one molar part menthol to a range of from about 0.0050 molar part to about 1.00 molar part, about 0.010 molar part to about 0.750 molar part, about 0.020 molar part to about 0.50 molar part, about 0.050 molar part to about 0.250 molar part, or about 0.10 molar part of at least one of the menthol stabilizer compounds (i.e., one of the menthol stabilizer compounds or a mixture of more than one of the menthol stabilizer compounds) included herein, preferably a molar ratio of about one molar part menthol to at most about 0.50 molar part, at most about 0.250 molar part or at most about 0.10 molar part of one or more than one of the menthol stabilizer compounds included herein. Such mixtures of menthol, solvent and menthol stabilizer compounds may be used when smaller amounts of menthol need to be stabilized (where the amount of menthol stabilizer compound to be mixed with the menthol is so small that there isn’t enough of it to dissolve the menthol).

[0045] Both menthol stabilized or less volatile compositions (i.e., where the menthol is first dissolved in a solvent then added to (e.g., dissolved in) a menthol stabilizer compound included herein or where the menthol is directly dissolved in a menthol stabilizer compound included herein) can be used in orally administrated and non-orally administrated compositions (e.g., non-orally topically administrated compositions (e.g., place on the skin or other external tissues)). However, the menthol stabilizer compounds can have a bitter taste. The dissolving of the menthol in solvent prior to the addition of at least one of the menthol stabilizer compounds included herein is preferably used in menthol containing therapeutic compositions to be administered orally because by first dissolving the menthol in a suitable solvent, less of the menthol stabilizer compounds may be used, thus lessening the bitter taste of the menthol stabilized composition and the final product in which it is included that is imparted by the menthol stabilizer compound.

[0046] The transdermal delivery systems, patches, vehicles and devices of the present disclosure can be of a suitable size and shape to fit against a body part so as to be applied to the skin surface thereof. One embodiment of the transdermal delivery systems, patches, vehicles and devices of the present disclosure include a hydrogel alone or in combination with a backing material. Examples of suitable backing material can include non-woven-fabric material, including, for example, PET/polyester, polyimide, PVC/Vinyl, silicone, acrylics, PTFE’s, LDPE/HDPE, polypropylene/ethylene/etc. , PVDC cotton, rayon, polyester, and blends thereof also including, for example, an acrylic PSA (pressure sensitive adhesive). The backing material can remain with the hydrogel upon application to a body part or can be a release layer that is removed subsequent to application of the embodiment to a body part. A suitable size for the hydrogel alone or in combination with a backing material or iontophoretic transdermal delivery system, patch, vehicle or device embodiments of the present disclosure, for example, is illustrated in FIG. 1 which can include the shape of a square or rectangle 100 or other polygon shape (including, e.g., triangle, pentagon, hexagon, etc.) with surface areas 102 and 104 (on opposing sides) and the dimensions of sides 106, 107, 1 10 and 112, each ranging in length 1 14, 1 16, 1 18 and 120, respectively ranging from about 2.0 cm to about 8.0 cm including each surface area ranging from about 4.0 cm ² to about 64.0 cm ² . For example, embodiments could include patches with sides 106, 107, 1 10 and 1 12, each ranging in length 1 14, 1 16, 1 18 and 120, respectively, that are about 2.0 cm. x about 4.0 cm (surface area about 8.0 cm ² ) or 8.0 cm. x about 9.0 cm (surface area about 72.0 cm ² ).

Volumes of the hydrogel components in embodiments of the present disclosure can range from about 0.10 ml to about 5.0 ml, in keeping with the above dimensions including about 2.0 ml. For example, the above referenced embodiments that include hydrogel components with a surface area 8.0 cm ² based on the above ranges of thickness could have volumes ranging from about 0.50 ml to about 2.0 ml.

[0048] In the embodiments of illustrated in FIG.1 a square would have sides 105, 107, 1 10 and 112 approximately equal in dimensions while a rectangle would have sides 106 and 1 10 approximately equal in dimensions along with sides 107 and 1 12 approximately equal, but the dimensions of sides 106 and 1 10 may not always be equal to the dimension of sides 107 and 112. In other embodiments, the dimensions of any one of sides 106, 107, 1 10 and 1 12 may be equal to the dimensions of the other sides.

[0049] Other embodiment shapes for the hydrogel alone or in combination with a backing material or in combination with other components of the iontophoretic transdermal delivery system, patch, vehicle or device embodiments of the present disclosure can also include a circle 200 illustrated in FIG. 2A having a generally circular shape with surface areas 202 and 204 on opposing sides thereof or an ellipse 206 illustrated in FIG. 2B and with surface areas 208 and 210 on opposing sides thereof. Diameter 212 for FIG. 2A and diameter 214 for FIG. 2B can range from about 1 .0 cm to about 8.0 cm including each surface area ranging from about 0.79 cm ² to about 50.27 cm ² .

[0050] The thickness 216 for hydrogels in embodiments of the present disclosure in circle 200 in FIGS. 2A and thickness 218 ellipse 206 in FIG. 2B can range from about 0.10cm to about 0.15 cm. For the iontophoretic transdermal delivery system, patch, vehicle or device embodiments of the present disclosure, patch thickness 122 can range from about 0.18 cm to about 0.22 cm.

[0051] Unit dosage formulations of the embodiments of the present disclosure can include cannabinoid, for example, a phytocannabinoid (including for example, CBD) in the amount per unit of surface area (e.g., surface areas 102 and 104 in FIG.1 , in FIG. 2A with surface areas 202 and 204 and in FIG. 2B and with surface areas 208 and 210) of about 5.0 mg./cm ² to about 1000.00 mg./cm ² . Unit dosage formulations of the embodiments of the present disclosure can include CBD in the amount of about 1 .25 mg./cm ² to about 250 mg./cm ² . Unit dosage formulations of the embodiments of the present disclosure can include full spectrum CBD or hemp oil in an amount of about 5.0 mg./cm ² to about 5000 1000.00 mg./cm ² . In one embodiment the full spectrum hemp oil is present at about 4 wt% of the hydrogel and includes a dosage of about 200mg. An effective amount of cannabinoid includes an analgesic, pain relieving, pain treating or anti-inflammatory amount of cannabinoid.

[0059] Another exemplary embodiment of the present disclosure is an iontophoretic transdermal delivery system, patch, vehicle or device of the present disclosure shown in an exploded illustration in FIG. 5A and a top assembled view in FIG. 5B. The iontophoretic patch or transdermal delivery system 500 includes a top layer 502 that can be non-woven material with or without perforations thereon such as cotton, rayon, polyester, LDPE (low density polyethylene), HDPE (high density polyethylene), polypropylene and blends thereof. Iontophoretic patch or transdermal delivery system 500 also includes a circuit apparatus that includes a battery 504 and can optionally include additional electrode conductive components between battery 504 and hydrogel material 518 and 520 (e.g., hydrogel reservoirs) including, for example, two strips of conductive tape 510 and 512 and flat conductive material 514 and flat conductive material 516. For example, a first electrode can include conductive tape 510 and flat conductive material 514 and a second electrode can include conductive tape 512 and flat conductive material 516. Battery 504 includes positive terminal 506 (an anode) and negative terminal 508 (a cathode) facing toward and each terminal in contact with one of two strips of conductive tape 510 and 512, respectively, the conductive tape 510 in contact with a flat conductive material 514 and conductive tape 512 in contact with flat conductive material 516. Examples of the materials that can be used as the conductive tape include, for example, acrylics, epoxies, hydrocolloids, hydrogels, rubber based thermoplastics, polyurethanes silicones and cyanoacrylates. Side 517 of the top layer 502 should include an adhesive layer in order to secure the other components of iontophoretic patch or transdermal delivery system 500 that contact it and to provide the portion of the top layer 502 that extends beyond the peripheral sides 509, 51 1 , 513 and 515 of the other components. The peripheral sides 501 , 503, 505 and 507 of the top layer 502 should extend beyond the peripheral sides adjacent and substantially or approximately parallel thereto 509, 511 , 513 and 515 of the other components such that distances 517, 521 , 523 and 525 range from about 0.10 inch to about 0.50 inch, about 0.25 in.

[0060] Conductive tape 510 and conductive tape 512 can be the same material or difference materials. Examples of the materials that can be used as the conductive tape 510 and 512 include, for example, metal foil, gold, platinum, silver (e.g., various silver compounds including silver oxide, silver chloride, etc.), aluminum, copper, iron, conductive polymers, etc. Examples of the materials that can be used as the flat conductive material 514 and 516 include, for example, metal foil, gold, platinum, silver, aluminum, copper, iron, conductive polymers, etc. Flat conductive material 514 and flat conductive material 516 can be the same material or difference materials. The battery 504 should be sufficient to have 1 -2 volts and 1 -2 mamps (less would not allow the embodiment to work sufficiently and more would damage, e.g., burn, the skin during use). The battery 504 can be alkaline, zinc-carbon, nickel metal hydride, lithium ion, silver oxide, zinc air, lithium, nickelcadmium. The conductive tape 510 and flat conductive material 514 are in contact with the positive terminal 506 of battery 504 (either directly or indirectly , the latter using an intervening conductor such as, for example, additional conductive tape and/or flat conductive material including conductive wire) and act as an anode and the conductive tape 512 and flat conductive material 516 are in contact with the negative terminal 508 of battery 504 (either directly or indirectly , the latter using an intervening conductor such as, for example, additional conductive tape and/or flat conductive material including conductive wire) and act as a cathode. Hydrogel material 518 and 520 are as included previously in the present disclosure and are disposed on and in contact flat conductive material 514 and 516, respectively, and positioned on the opposing sides of flat conductive material 514 and 516, respectively, to conductive tape 510 and conductive tape 512, respectively and, thereby to battery 504 and the positive terminal 506 and the negative terminal 508, thereof. The hydrogel material 518 and 520 are approximately the same lateral dimensions as the flat conductive material 514 and 516 on which they are disposed on and in contact with such that sufficient electrical power can pass from the battery to the hydrogel material 518 and 520 and complete the electrical circuit to accomplish the delivery of the active agents from the hydrogel material into the skin of a person as described in more detail below. The size of conductive tape 510 and conductive tape 512 is such that sufficient electrical power can pass from the battery to the flat conductive material 514 and 516 and hydrogel material 518 and 520 to complete the electrical circuit to accomplish the delivery of the active agents from the hydrogel material into the skin of a person as described in more detail below. There is a gap 522 that separates conductive tape 510 from conductive tape 512, flat conductive material 514 from flat conductive material 516 and hydrogel material 518 disposed on flat conductive material 514 from hydrogel material 520 disposed on flat conductive material 516.

[0061] One of the hydrogel materials 518 and 520 need to include an anionic or cationic surfactant, preferably an anionic surfactant along with the active agents (e.g., cannabinoids and menthol). As noted above, if the embodiment of the present disclosure includes a humectant, both hydrogel reservoirs will include the humectant. Because the active agents (e.g., cannabinoids and menthol) have a neutral charge, if the surfactant is anionic, the hydrogel material on the cathode side also includes the active agents (e.g., cannabinoid and menthol) to be delivered by the iontophoretic patch such that when electrical circuit is closed, the active agents migrate toward the anode and if the surfactant is cationic, the hydrogel material on the anode side also includes the active agents (e.g., cannabinoid and menthol) to be delivered by the iontophoretic patch such that when electrical circuit is closed, the active agents migrate toward the cathode. [0062] Examples of anionic surfactants that can be used in embodiments of the present disclosure include sodium docusate (which may also act as a skin penetration enhancer as well as an ionic carrier), ammonium lauryl sulfate, sodium laureth sulfate, sodium lauryl sarcosinate, sodium myreth sulfate, sodium pareth sulfate, sodium stearte, sodium lauryl sulfate, a olefin sulfonate, and ammonium laureth sulfate). Examples of cationic surfactants that can be used in embodiments of the present disclosure include benzalkonium, benzethonium, methylbenzethonium, cetylpyridinium, alkyl-dimethyl dichlorobenzene ammonium, dequalinium and phenamylinium chlorides, cetrimonium and cethexonium bromides). Such surfactants can be in an amount of from about 1 wt% to about 10 wt% (wt% based on the hydrogel weight), about 5 wt% (wt% based on the hydrogel weight) including about 5 wt% sodium docusate (anionic) (wt% based on the hydrogel weight).

[0063] The electrical circuit is completed by placing the iontophoretic patch 500, hydrogel sides down against the skin of a person, as described above, whereby the positive side of the iontophoretic patch or transdermal delivery system 500 is electrically connected to the negative side of the iontophoretic patch 500 through the skin of the person on which it is placed. Once the circuit is complete, the electrical current pulls the hydrogel material with the active agents from the terminal where it is disposed through and into the skin of the person and toward the opposite terminal. As a result, the active agents are administered to the person at the site of the iontophoretic patch 500. For example, where the If the surfactant is anionic and the hydrogel material on the cathode side (e.g., negative terminal 508 conductive tape 512, flat conductive material 516 and hydrogel material 520) also includes the active agents along with the anionic surfactant when electrical circuit is closed, the active agents migrate through the skin toward the anode. For example, where the If the surfactant is cationic and the hydrogel material on the anode side (e.g., positive terminal 506 conductive tape 510, flat conductive material 514 and hydrogel material 518) also includes the active agents along with the cationic surfactant when electrical circuit is closed, the active agents migrate through the skin toward the cathode. Salt ions in the skin aid in completing the circuit between the anode side and the cathode side of the iontophoretic patch. [0064] Another exemplary embodiment of the present disclosure similar in both structure and operation to the iontophoretic patch shown in FIGS. 5A and 5B is an iontophoretic transdermal delivery system, patch, vehicle or device shown in FIGS. 5C and 5D.

Iontophoretic patch 522 includes a top layer 521 , a battery 524 with positive terminal 526 and negative terminal 528 facing toward and each terminal in contact with one of two strips of conductive tape 530 and 532, respectively, the conductive tape 530 in contact with a flat conductive material 534 and conductive tape 532 in contact with flat conductive material 536. The conductive tape 530 and flat conductive material 534 are in contact with the positive terminal 526 of battery 524 acts as an anode and the conductive tape 532 and flat conductive material 536 are in contact with the negative terminal 528 of battery 524 acts as a cathode. Iontophoretic patch or transdermal delivery system 522 also includes a circuit apparatus that includes a battery 524 and can optionally include additional electrode conductive components between battery 524 and hydrogel material 538 and 540 (e.g., hydrogel reservoirs) including, for example, two strips of conductive tape 530 and 532 and flat conductive material 534 and flat conductive material 536.

Hydrogel material 538 and 540 are disposed on and in contact flat conductive material 534 and 536 on the opposing side thereof to conductive tape 530 and the conductive tape 532, respectively. There is a gap 542 that separates conductive tape 530 from conductive tape 532, flat conductive material 534 from flat conductive material 536 and hydrogel material 538 from hydrogel material 540 disposed on flat conductive material 536.

[0068] The components embodiment of FIGS. 5C and 5D are similar to those in the embodiment of FIGS. 5A and 5B, one difference being that the flat conductive material and hydrogel disposed thereon for the anode is larger in area than the flat conductive material and hydrogel disposed thereon for the cathode and the active agents are disposed in the hydrogel on the anode.
