  • Dermal tissue is composed of epidermal cells, closely packed cells that secrete a waxy cuticle that aids in the prevention of water loss.
  • Ground tissue lies between dermal tissue and vascular tissue.
  • the ground tissue comprises the bulk of the primary plant body. Parenchyma, collenchyma, and sclerenchyma cells are common in the ground tissue. In roots, the ground tissue may store sugars or starches to fuel the spring sap flow; in leaves, the ground tissue is the layer responsible for photosynthesis (the mesophyll) .
  • Vascular tissue transports food, water, hormones and minerals within the plant. Vascular tissue includes xylem, phloem, parenchyma, and cambium cells.

Most are green and contain chlorophyll, though they vary in their shapes and sizes. Leaves are the part of the plant that ordinarily performs photosynthesis (the process that converts sunlight and carbon dioxide into energy) .
  • needle generally refers to a narrow stiff leaf, such as those of conifers (e.g., pine trees) .

By germination, most seeds produce a new plant. "Seed” also refers to any small seedlike fruit, though it may consist of a pericarp, or even a calyx, as well as the seed proper, such as a parsnip seed or thistle seed. The seed proper has an outer and an inner coat, and within these the kernel or nucleus. The kernel is either the embryo alone, or the embryo enclosed in the albumen, which is the material for the nourishment of the developing embryo. The scar on a seed, left where the stem parted from it, is called the hilum, and the closed orifice of the ovule, the micropyle .

It is also possible for some organic molecules and some inorganic salts to associate with the hydroxyl groups of the cyclodextrin. Three cyclodextrins are typically formed, alpha, beta, and gamma cyclodextrin, which contain six, seven, or eight glucose molecules in the ring, respectively.

The disclosed subject matter provides an adhesive patch that includes an aversive agent. The aversive agent is present in a known, discrete, safe (non- toxic), and effective amount. Having a relatively unpleasant taste, the aversive agent effectively minimizes and discourages the occurrence of an animal (e.g., human) from accidentally ingesting the adhesive patch, after the adhesive patch is orally administered. As such, the adhesive patch of the disclosed subject matter may include substances not intended for oral administration, with a diminished likelihood that an animal will ingest the adhesive patch.
The aversive agent has minimal or no therapeutic activity. Additionally, the aversive agent is both topically and orally safe. As such, the adhesive patch will be permitted by any relevant federal or local authority (e.g., the United States Food and Drug Administration (FDA) ) .
The adhesive patch is convenient to use. The adhesive patch also maintains the stability of the aversive agent over an extended period of time. Likewise, the aversive agent will have minimal or no adverse affects upon the functional characteristics of the adhesive patch. For example, the aversive agent will have minimal or no adverse affects upon the stability of the components present in the adhesive patch. The aversive agent will also have minimal or no adverse affects upon the therapeutic effectiveness of the medicaments present in the adhesive patch. Additionally, the aversive agent will have minimal or no adverse affect upon the requisite adhesiveness of any pressure sensitive adhesives present in the adhesive patch.
References in the specification to "one embodiment", "an embodiment", "an example embodiment", etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment . Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.
Transdermal Patch
In a specific embodiment of the disclosed subject matter, the aversive agent may be included in a transdermal patch.
As used herein, a "transdermal patch" refers to a medicated adhesive patch that is placed on the skin, to deliver a time released dose of medicament through the skin and into the bloodstream. A wide variety of pharmaceuticals may be delivered by transdermal patches. Suitable transdermal patches include, e.g., nicotine patches, which release nicotine to help quitting the habit of tobacco smoking. Other transdermal patches administer estrogen for menopause and to prevent osteoporosis after menopause; nitroglycerin for angina; and lidocaine to relieve the pain of shingles (herpes zoster) . Recent developments expanded their use to the delivery of hormonal contraceptives, antidepressants and even pain killers. Some medicaments are combined with substances, such as alcohol, that increase their ability to penetrate the skin in order to be used in a transdermal patch.
Specific exemplary transdermal patches include, e.g., NicoDerm®, also known as NicoDerm CQ®, which are over the counter palliative nicotine replacement therapy used to ameliorate the withdrawal effects involved in quitting smoking. Alternative brand names include Prostep®, Habitrol®, Nicotrol®, Nicorette, and
Commit®.
In a specific embodiment of the disclosed subject matter, a unique adhesive vehicle is provided. The vehicle has pressure sensitive adhesive qualities due to its composition and viscoelastic nature. The adhesive is hydrophilic and therefore water may dissolve into or evaporate from the adhesive, depending on the conditions to which it is exposed. This water exchange capability implies that if the adhesive is on a suitably porous backing and is applied to the skin, it will not be occlusive as most drug delivery patches are. The occlusive nature of conventional drug delivery patches is thought to play an important role in enhancing drug absorption, but also often results in greater incidence of skin irritation. The relatively low occlusiveness of the disclosed subject matter may be envisioned to be a special adhesive ointment or gel which is water- breathable, such as a water washable or water soluble ointment or gel .
In a specific embodiment of the disclosed subject matter, an ointment or gel on a backing is provided. The ointment or gel includes an aversive agent in a known, discrete, safe, and effective amount. The adhesive patch maintains the stability of the aversive agent over an extended period of time. The backing is pliable and/or stretchable. Since the backing may be porous and/or vapor permeable, many consumers typically refer to the device as a "patch, " a "skin patch," or an "adhesive skin patch." As such, the device (i.e., the ointment or gel on the backing) will herein be referred to as a patch, a skin patch or an adhesive skin patch. It is appreciated that those skilled in the art understand that the term "patch" is used to refer to the device and is not otherwise limiting in any manner.
It is appreciated that those of skill in the art understand that the terms used herein, unless expressly stated otherwise, include the singular as well as the plural. For example, the term "aversive agent" 15 includes the singular (i.e., one aversive agent) as well as the plural (i.e., two or more aversive agents) .
As used herein, "holdout" refers to the physical properties of a backing, relating to the ability of a specific class of gels or ointments to penetrate, cross-link, wet, and/or cure within the matrix of the backing. A specific class of gels or ointments may or may not be able to penetrate a given backing. Upon penetration of a gel or ointment into a backing, the gel or ointment will cross-link, wet, or cure in the backing. As such, the holdout properties are the ability of the gel or ointment to affect the degree of penetration, cross-linking, wetting, and/or curing within the matrix of the backing. Those backings with superior holdout properties will typically prevent, decrease, or lessen the likelihood of the ointment or gel from wetting the backing; will typically increase the likelihood of the ointment or gel to cross-link within the matrix of the backing; will typically increase the likelihood of the ointment or gel to cure within the matrix of the backing; and/or will typically increase the likelihood of the ointment or gel to partially penetrate the matrix of the backing. Referring to Figures 1-10, an adhesive patch 1 of the disclosed subject matter is provided. The adhesive patch 1 includes a formulation 5 located on at least a portion of the front side 3 of the backing 2, in at least a portion of the front side 3 of the backing 2, or on and in at least a portion of the front side 3 of the backing 2. Specifically, the formulation 5 is partially embedded in at least a portion of the front side 3 of the backing 2. In addition to being located in at least a portion of the front side 3 of the backing 2, the formulation 5 is located on a portion of the surface of front side 3 of the backing 2. Specifically, the formulation 5 is located on the entire surface of the front side 3 of the backing 2.
Backing
The backing 2 is defined by a front side 3 (the side exposed to the skin during use) and a back side 4 (the side exposed to the environment during use) . The backing 2 should be nonirritating to human skin. The backing 2 is a self-supporting sheet of water soluble or water insoluble, polymeric or natural material that provides strength and integrity for the formulation 5. The backing 2 of the adhesive patch 1 may be vapor permeable. As such, the backing 2 may be porous, since porosity provides openings for receiving the formulation 5 and it helps to assure that the adhesive skin patch 1 is vapor permeable. Alternatively, in specific embodiments, the backing 2 may be non-porous, such that the adhesive skin patch 1 is relatively occlusive.
Specifically, the backing 2 may retain the formulation 5 while allowing moisture from the skin to pass. The backing 2 may have any suitable thickness, provided the suitable thickness allows for a flexible, bendable, pliable, vapor permeable, and/or a stretchable sheet of water insoluble porous material . Specifically, the thickness of the backing 2 may be about 0.001 mm to about 5.0 mm, about 0.001 mm to about 3.0 mm, or about 0.025 mm to about 1.25 mm.
The backing 2 may be manufactured from any suitable material, provided the suitable material may form a flexible, bendable, pliable, and/or stretchable backing 2. The backing 2 includes a flexible porous sheet of water soluble or water insoluble material that provides support for the adhesive skin patch 1. The backing 2 may include water soluble or -water insoluble polymeric fibers, a porous film, or any other kind of matrix with spaces within the matrix. A specific backing 2 is a lightweight, porous, pliable strip composed of a nonwoven fabric of polymeric or natural fibers such as polyester, polyolefin, cotton or cellulose fibers bonded together with a sizing resin, entanglement, or thermal process. The backing 2 may be woven or nonwoven. Specifically, the backing 2 includes nonwoven fabric. Alternatively, in specific embodiments, the backing 2 may include open cell foam.
Specifically, the backing 2 may include polyester fibers, polyurethane fibers, polyolefin fibers, polyamide fibers, natural fibers, cotton fibers, copolyester fibers, cellulose acetate fibers, polycellulose fibers, or any mixture thereof. Additional stable, water insoluble flexible sheet materials and methods for manufacturing the suitable backings 2 are disclosed, e.g., in U.S. Patent No. 4,675,009; U.S. Patent No. 5,536,263; U.S. Patent No. 4,696,854; U.S. Patent No. 5,741,510, and references cited therein, and are suitable as backings 2 according to the disclosed subject matter. The infusion of the formulation 5 into the backing 2 may be accomplished, e.g., with the use of a continuous process mixer, as disclosed, e.g., in U.S. Patent No. 5,536,263, and references cited therein; or as discussed herein.
Alternatively, the backing 2 may be a non-woven backing 2 that is treated by coating: the front side 3 of the backing adhesive patch 1, the back side 4 of the backing 2, or both the front side 3 and back side 4 of the backing 2; with a silicone-containing compound, a fluorocarbon solution, or a combination thereof. Suitable silicone-containing compounds include, e.g., polydimethyl siloxanes, dialkylsiloxanes , dimethylsiloxo vinyl alkenes, dialkylsiloxo vinyl alkenes, dimethylsiloxo acrylates, dialkylsiloxo acrylates, vinyl terminated polydimethylsiloxane, and vinyl terminated polydialkylsiloxane . The exemplary silicone- containing compounds are commercially available from, e.g., Goldschmidt Chemical Corp. (Essen, Germany); GE Silicones (Waterford, NY) ; Wacker Silicone Corp. (Adrian, MI) ; and Dow Corning Corp. (Midland, MI) .
The backing 2 may be manufactured from a suitable non-woven fabric that is commercially available from, e.g., Freudenberg Faservliesstoffe KG (Weinham,
Germany) ; Sontara Technologies (division of DuPont Corporation) (Old Hickory, TN); Lystil S. A. (Brignoud Cedex, France) ; Dexter Nonwovens (Windsor Locks, CT) ; and Chicopee (New Brusnwick, NJ) . Other commercial vendors that supply suitable non-woven fabrics may be found at the Technical Textiles and Nonwoven website (http://www.ttna.com.au/) , April 23, 2007.
It has surprisingly been discovered that the use of a treated backing, such as a fluorocarbon treated non-woven backing, typically increases the yield of an adhesive patch. The use of a backing material that has been treated with a sizing agent allows for the effective control of the rate of penetration, such that the gel or ointment has solidified after it has begun to penetrate the backing, but before it has passed completely through the backing. In addition, the use of a backing material that has been treated with a sizing agent allows for the effective control of the depth to which the ointment or gel will easily penetrate before solidifying. It has surprisingly been discovered that increasing the control of the rate at which the ointment or gel penetrates the backing typically improves the overall yield of the production process by reducing the amount of material which must be discarded because the back side of the backing has become too tacky for either processing or for consumer acceptance. At least a portion of the backing 2 may be treated with a sizing agent 8 such that the portion of the backing 2 that is treated with the sizing agent 8 has a surface energy of about 20 dynes/cm2 to about 65 dynes/cm2. Specifically, the portion of the backing 2 that is treated with the sizing agent 8 may have a surface energy of about 27 dynes/cm2 to about 56 dynes/cm2. The sizing agent 8 lowers the surface energy of the portion of the backing 2 that is treated with the sizing agent 8. Any suitable sizing agent 8 may be employed, provided the portion of the backing 2 that is treated with the sizing agent 8 has a surface energy of about 20 dynes/cm2 to about 65 dynes/cm2. Suitable sizing agents 8 include, e.g., fluorocarbon solutions, silicone-containing compounds, and combinations thereof. Specifically, the backing 2 may be a non-woven backing 2 that is treated with a fluorocarbon. For example, the fluorocarbon treated backing 2 may be, e.g., Vilmed M1585 W/HY, Vilmed M1585H/HY, Vilmed M1586 W/HY, Vilmed M1586 H/HY, Vilmed M1570, Vilmed M1573 F, Vilmed M1573 FH, Vilmed M1577 F, Vilmed M1578 F, or Vilmed M1578 FH; which are all commercially available from Freudenberg Faservliesstoffe KG (Weinham, Germany) . Alternatively, the silicone treated backing 2 may be a non-woven backing 2 that is coated with one or more silicone-containing compounds, e.g., a polydimethyl siloxane, a dialkylsiloxane, a dimethylsiloxo vinyl alkene, a dialkylsiloxo vinyl alkenes, a dimethylsiloxo acrylate, a dialkylsiloxo acrylate, a vinyl terminated polydimethylsiloxane, and a vinyl terminated polydialkylsiloxane .
At least a portion of the backing 2 may be treated with the sizing agent 8. The portion of the backing 2 that is treated with the sizing agent 8 may be that portion of the backing 2 that may typically include the formulation 5. The entire surface of the front side 3 of the backing 2 may be treated with the sizing agent 8 or a portion of the surface of the front side 3 of the backing 2 may be treated with the sizing agent 8. Specifically, the entire surface of the front side 3 of the backing 2 may be treated with the sizing agent 8. In addition to the surface of the front side 3 of the backing 2 being treated with the sizing agent 8, the sizing agent 8 may penetrate at least a portion of the underlying surface (e.g., one- tenth to about nine-tenths the thickness, or about one-fourth to about nine-tenths the thickness) of the backing 2. Specifically, the sizing agent 8 may penetrate the entire underlying surface of the backing 2.
Suitable fluorocarbon treated backings 2 include, e.g., Vilmed M1585 W/HY, Vilmed M1585H/HY, Vilmed M1586 W/HY, Vilmed M1586 H/HY, Vilmed M1570, Vilmed
M1573 F, Vilmed M1573 FH, Vilmed M1577 F, Vilmed M1578 F, and Vilmed M1578 FH; which are all commercially available from Freudenberg Faservliesstoffe KG (Weinham, Germany) . As shown in Figs. 1-6 and 9-10, the backing 2 includes a front side 3 and a back side 4. The adhesive skin patch 1 includes a formulation 5 located in at least a portion of the front side 3 of the backing 2, on at least a portion of the front side 3 of the backing 2, or on and in at least a portion of the front side 3 of the backing 2. As such, the formulation 5 may be located on the entire surface of the front side 3 of the backing 2 or the formulation 5 may be located on a portion of the surface of the front side 3 of the backing 2.
Specifically, the formulation 5 may be located on the entire surface of the front side 3 of the backing 2. In addition to being located on the surface of the front side 3 of the backing 2, the formulation 5 may be located in at least a portion of the underlying surface of the front side 3 of the backing 2 (i.e., the formulation 5 may be partially embedded into the backing 2) .
As shown in Figure 9, the formulation 5 may penetrate a substantial portion of the front side 3 of the backing 2, as disclosed, e.g., in U.S. Patent No. 5,536,263, and references cited therein. For example, the formulation 5 may penetrate about one-tenth to about nine-tenths the thickness of the backing 2, or about one-fourth to about nine-tenths the thickness of the backing 2. As such, the formulation 5 may be partially embedded into the backing 2. Specifically, the formulation 5 may be located on the entire front side 3 of the backing 2 and partially in the front side 3 of the backing 2 (i.e., the formulation 5 is partially embedded into the backing 2) .
Alternatively, a portion of the front side 3 of the backing 2 may include the formulation 5 and other portions of the front side 3 of the backing 2 may include any combination of the pressure sensitive adhesive 14 and solvent 13. For example, a central circular portion of the front side 3 of the backing 2 may include the formulation 5 while the remaining portions of the front side 3 of the backing 2 include only the pressure sensitive adhesive 14. The formulation 5, when partially embedded into the front side 3 of the backing 2, imparts strength and structure into the adhesive patch 1. For example, when the formulation 5 is partially embedded into the backing 2, the likelihood that the adhesive patch 1 will tear apart when separated from the release liner 10 or when removed from the skin after use, is minimized.
When the adhesive skin patch 1 is placed upon the skin of a patient (e.g., human), the formulation 5 may be in continuous contact with the skin surface of the patient .
Specifically, the adhesive skin patch I7 upon contact with skin, will allow the skin to breathe. More Specifically, the adhesive skin patch 1, upon prolonged contact with skin, will hold in place the formulation 5 and will permit the skin to breathe over prolonged periods of time typically experienced with the use of the patch, e.g., up to about 24 hours, up to about 12 hours, up to about 8 hours, or up to about 6 hours .
As shown in Figs. 3-6 and 9, the adhesive skin patch 1 may be reversibly attached to a release liner 10. The release liner 10 helps to maintain the adhesiveness of the adhesive skin patch 1 prior to use, such as during manufacturing, packaging, shipping, and/or storage. Any suitable release liner 10 may be employed for use in the disclosed subject matter. Suitable release liners 10 are readily known to those of skill in the art. See, e.g., U.S. Patent No. 4,675,009; U.S. Patent No. 5,536,263; U.S. Patent No. 4,696,854; U.S. Patent No. 5,741,510, and references cited therein for further descriptions of release liners 10 useful in the disclosed subject matter. The release liner 10 may include a perforation 12 that allows the tab section 11 of the release liner 10 to be removed (see, Figs. 3, 5, and 6) . Removal of the tab section 11 of the release liner 10 allows the adhesive skin patch 1 to be removed from the release liner 10 with relative ease.

While the amount of medicament 21 present in the therapeutic formulation 5 may comply with FDA regulations (e.g., Federal Register, Vol. 48, No. 27, § 341), it is appreciated that those of skill in the art understand that the amount of medicament 21 present in the therapeutic formulation 5 may be higher than the amount permitted by the FDA. See, e.g., Handbook of Nonprescription Drugs, 10th Edition, 1993. This is because there may be a loss of concentration for the medicament 21 during the manufacturing, shipping or storage of the adhesive patch 1. As such, the FDA may allow for slightly more or slightly less (e.g., ±10%) medicament 21 to be present in the stability studies.
Aversive agent
As used herein, an "aversive agent" refers to any substance that is safe (non-toxic) when topically or orally administered, yet produces a relatively unpleasant taste upon oral administration. The relatively unpleasant taste may be, e.g., an extremely bitter taste. In a specific embodiment of the disclosed subject matter, the aversive agent 15 may be denatonium, or a suitable salt thereof.
As used herein, denatonium refers to N-benzyl-2- (2 , 6-dimethylphenylamino) -N, N-diethyl -2- oxoethanaminium. The compound is typically available as a benzoate or saccharide salt (anion) . Denatonium benzoate has a CAS Reg. No. of [3734-33-6] , and is structurally shown below.

See, e.g., U.S. Patent Nos. 6,652,632 and 7,144,587; U.S. Published Patent Application Nos. 2003/075073 Al and 2003/124185 Al; and Published PCT Patent Application Nos. WO/0145506 Al; WO/03013476 Al; WO/03013479 Al; WO/03035783 Al; WO/9301712 Al; and WO/07022563 Al.
In one specific embodiment of the disclosed subject matter, the aversive agent is not a substance disclosed in U.S. Patent No. 7,011,843.
Any suitable aversive agent 15 may be employed, in any suitable amount, provided:
(1) the aversive agent 15 is safe (non-toxic) for oral and topical administrataion,-
(2) the aversive agent 15 has such a relatively unpleasant taste, that it effectively discourages an animal (e.g., human) from ingesting it;
(3) the aversive agent 15 has minimal or no therapeutic activity; (4) the aversive agent 15 will have minimal or no adverse affects upon the functional characteristics of the adhesive patch 1; and
(5) the aversive agent 15 remains stable in the formulation 5.
Typically, the amount of aversive agent 15 present in the formulation 5 will depend upon the specific compound or compounds employed as the aversive agent 15. Specifically, the aversive agent 15 may be present in about 0.0001 wt . % to about 1.0 wt . % of the formulation 5. More specifically, the aversive agent 15 may be present up to about 1.0 wt . % of the formulation 5, up to about 0.1 wt . % of the formulation 5, or up to about 0.01 wt . % of the formulation 5. The adhesive skin patch 1 includes an aversive agent 15 located in at least a portion of the front side 3 of the backing 2, on at least a portion of the front side 3 of the backing 2, or on and in at least a portion of the front side 3 of the backing 2. As such, the aversive agent 15 may be located on the entire surface of the front side 3 of the backing 2 or the aversive agent 15 may be located on a portion of the surface of the front side 3 of the backing 2. Specifically, the aversive agent 15 may be located on the entire surface of the front side 3 of the backing 2.
In addition to being located on the surface of the front side 3 of the backing 2, the aversive agent 15 may be located in at least a portion of the underlying surface of the front side 3 of the backing 2 (i.e., the aversive agent 15 may be partially embedded into the backing 2) . As shown in Figure 9, the aversive agent 15 may penetrate a substantial portion of the front side 3 of the backing 2, as disclosed, e.g., in U.S. Patent No. 5,536,263, and references cited therein. For example, the aversive agent 15 may penetrate about one-tenth to about nine- tenths the thickness of the backing 2, or about one- fourth to about nine-tenths the thickness of the backing 2. As such, the aversive agent 15 may be partially embedded into the backing 2.
Specifically, the aversive agent 15 may be located on the entire front side 3 of the backing 2 and partially in the front side 3 of the backing 2 (i.e., the aversive agent 15 is partially embedded into the backing 2) . Alternatively, a portion of the front side 3 of the backing 2 may include the aversive agent 15 and other portions of the front side 3 of the backing 2 may include the pressure sensitive adhesive. For example, a central circular portion of the front side 3 of the backing 2 may include the aversive agent 15 while the remaining portions of the front side 3 of the backing 2 include only the pressure sensitive adhesive 14. When the adhesive skin patch 1 is placed upon the skin of a patient (e.g., human), the aversive agent 15 may be in continuous contact with the skin surface of the patient. The aversive agent 15 may be manufactured (i.e., synthesized or partially synthesized) . Alternatively, the aversive agent 15 may be obtained from a plant or plant component (e.g., plant tissue). Suitable plant or plant components include, e.g., a herb, flower, fruit, seed, bark, stem, root, needle, bulb, berry, rhizome, rootstock, leaf, or a combination thereof.
Plant Tissue As used herein, "plant tissue" refers to the tissue of any organism of the plant kingdom, as opposed to one of the animal kingdom or of the kingdoms of Fungi, Protista, or Monera . The plant tissue may be any portion or portions of the plant (e.g., bark, roots, leaves, flowers, needles, bulbs, berries, rhizomes, rootstocks, stems, and seeds) , as well as the entire plant. The tissues of a plant ("plant tissue") generally fall into three main categories: dermal tissue, ground tissue, and vascular tissue. Dermal tissue refers to the "skin" layer of all plant organs and is responsible for environmental interaction (light passage, gas exchange, pathogen recognition and protection, color display, etc.) . Dermal tissue is composed of epidermal cells, closely packed cells that secrete a waxy cuticle that aids in the prevention of water loss. Ground tissue lies between dermal tissue and vascular tissue. The ground tissue comprises the bulk of the primary plant body. Parenchyma, collenchyma, and sclerenchyma cells are common in the ground tissue. In roots, the ground tissue may store sugars or starches to fuel the spring sap flow; in leaves, the ground tissue is the layer responsible for photosynthesis (the mesophyll) . Vascular tissue transports food, water, hormones and minerals within the plant. Vascular tissue includes xylem, phloem, parenchyma, and cambium cells.
As used herein, "bark" refers to the dry, dead outer covering of woody branches, stems and roots of plants that is very distinct and separable from the wood itself. It includes all tissue outside the cambium (growth layer between bark and wood) . As used here the terms "leaf" or "leaves" refer to those parts of a plant which grow along the sides of branches or stems or at the bases of plants. Most are green and contain chlorophyll, though they vary in their shapes and sizes. Leaves are the part of the plant that ordinarily performs photosynthesis (the process that converts sunlight and carbon dioxide into energy) .
As used herein, "needle" generally refers to a narrow stiff leaf, such as those of conifers (e.g., pine trees) .
As used herein, "root" refers to the part of a plant, normally underground, that absorbs nutrients and anchors the plant into the ground. As used herein, "bulb" refers to a spheroidal body growing from a plant either above or below the ground (usually below) , which is usually a bud, consisting of a cluster of partially developed leaves, and producing, as it grows, a stem above, and roots below, (e.g., the onion or tulip bulb) . A true bulb is a complete package containing next year's plant (flower) already forming inside. The contents of the bulb are often enclosed in protective, fleshy scales, which are held together by a small basal plate. The scales are modified leaves that contain enough nutrients to sustain the plant through dormancy and early growth. They may be loose and open like those of a lily, or tightly closed like those of a hyacinth. In many bulbs, a paper-thin tunic protects the scales (lilies don't have a tunic) . Roots will grow from the bulb's basal plate.
As used herein, "berry" refers to any small fruit that is pulpy or succulent throughout, having seeds loosely imbedded in the pulp, such as the currant, grape, or blueberry. Berry may be further defined as an indehiscent fruit derived from a single ovary and having the whole wall fleshy, such as the grape or tomato. Furthermore, berries come in various structures including simple, such as grape; blueberry, cranberry, or aggregate, such as blackberry; raspberry, strawberry mulberry.
As used herein, "rhizome" refers to a horizontal, usually underground stem that often sends out roots and shoots from its nodes (also called rootstalk or rootstock) .
As used herein, "rootstock" refers to a robust plant that provides the root system in grafting, also known as a stock. Scions and buds are grafted and budded to a rootstock or stock. Rootstock also refers to the elongated and often thick rhizomes of certain perennial herbaceous plants such as the Iris, Aspidistra and Solomon's Seal. As used herein, "stem" refers to the main
(usually aerial) axis (sometimes referred to as the trunk or stalk) of a tree, shrub, or plant. "Stem" also refers to the part of the plant that supports the leaves, flowers or fruits of a plant, such as the peduncle of a fruit or the pedicel of a flower.
As used herein, "seed" refers to a ripened ovule, consisting of an embryo with one or more integuments, or coverings, such as an apple seed, a currant seed, dill seed, or kola nut seed. By germination, most seeds produce a new plant. "Seed" also refers to any small seedlike fruit, though it may consist of a pericarp, or even a calyx, as well as the seed proper, such as a parsnip seed or thistle seed. The seed proper has an outer and an inner coat, and within these the kernel or nucleus. The kernel is either the embryo alone, or the embryo enclosed in the albumen, which is the material for the nourishment of the developing embryo. The scar on a seed, left where the stem parted from it, is called the hilum, and the closed orifice of the ovule, the micropyle .
Solvent When present, the solvent 13 may act as a carrier for, and specifically may dissolve, the formulation 5 or any component (s) thereof (e.g., medicament 21 and/or aversive agent 15) . Any suitable solvent 13 may be employed, provided the solvent 13 effectively dissolves the formulation 5 or any component (s) thereof, and the solvent 13 remains stable in the formulation 5.

More specifically, the solvent 13 may be present in about 1.0 wt% to about 70.0 wt. %; in about 3.0 wt% to about 50.0 wt. %; or in about 5 wt . % to about 30 wt . % of the formulation 5. Typically, the amount of solvent 13 will depend on the compound or compounds employed as the solvent 13. For example, a polyhydric alcohol may be present up to about 70 wt .% of the formulation 5; or in about
20.0 wt .% to about 60.0 wt . % of the formulation 5; and water may be present in about 2.0 wt . % to about 50.0 wt .% of the formulation 5.
When present, the solvent 13 may be located in at least a portion of the front side 3 of the backing 2, on at least a portion of the front side 3 of the backing 2, or on and in at least a portion of the front side 3 of the backing 2.

Complexing Agent
In one embodiment of the disclosed subject matter, the formulation 5 may include an aversive agent 15 and/or medicament 21 that is not soluble and/or stable either without a solvent or with the specific solvent 13, in the amount employed. The use of a complexing agent may be employed to modulate (i.e., regulate) the solubility, stability, and/or the volatility of the aversive agent 15 and/or medicament 21 in the formulation 5. Any suitable complexing agent may be employed, provided the complexing agent effectively solubilizes and/or stabilizes the aversive agent 15 and/or and/or medicament 21, and the complexing agent remains stable in the formulation 5 over a prolonged period of time. Specifically, the stability is over a prolonged period of time, e.g., up to about 3 years, up to about 1 year, or up to about 6 months, typically experienced in the manufacturing, packaging, shipping, and/or storage of the adhesive skin patch 1.
In addition, any suitable amount of complexing agent may be employed, provided the amount of complexing agent effectively solubilizes and/or stabilizes the aversive agent 15 and/or and/or medicament 21, and the amount of complexing agent remains stable in the formulation 5 over a prolonged period of time. Suitable specific complexing agents include, e.g., cyclodextrins . As used herein, a "cyclodextrin" refers to a non-reducing cyclic oligosaccharide with at least 6 anhydroglucose units linked by alpha 1,4 bonds to form a ring. Cyclodextrins are typically produced by the action of the enzyme cyclodextrin glucosyltransferase [CGT-ase] on starch. The most common cyclodextrins include alpha, beta, and gamma cyclodextrins, which have six, seven, or eight, respectively, anhydroglucose units in the ring structure. All of the hydroxyl groups in cyclodextrins are oriented to the outside of the ring while the glucosidic oxygen and two rings of the non- exchangeable hydrogen atoms are directed towards the interior of the cavity. This combination gives cyclodextrins a hydrophobic inner cavity and a hydrophilic exterior. See, e.g., the Cerestar website (http://www.cerestar.com); the Betadexcyclodextrin website (http://www.betadexcyclodextrin.com); and M. L. Bender and M. Komiyama, Cyclodextrin Chemistry, Springer, Berlin, 1978.
Cyclodextrins are enzymatically-modified starches formed by the action of the enzyme cyclodextrin glucosyltransferase on starch. They are doughnut - shaped molecules, which may interact with organic molecules to form complexes. It is also possible for some organic molecules and some inorganic salts to associate with the hydroxyl groups of the cyclodextrin. Three cyclodextrins are typically formed, alpha, beta, and gamma cyclodextrin, which contain six, seven, or eight glucose molecules in the ring, respectively. The electron-dense glycosidic oxygen atoms are oriented inward and line the cavity. The hydroxyl groups are directed toward the outside of the ring. These hydrophilic groups interact with the water to give the cyclodextrins their aqueous solubility properties. The hydrogen and glycosidic oxygen atoms lining the cavity give the cyclodextrin molecule its hydrophobic character and its ability to interact with organic molecules to form complexes. Because of the free rotation of the C- 6 carbon, this end of the cyclodextrin cavity is narrower than the end with the C-2 and C-3 hydroxyls. Derivatives of cyclodextrin may be obtained, e.g., by replacing one or more hydroxyl groups with a suitable radical (i.e., pendant group). Suitable pendant groups include, e.g., sulfinyl; sulfonyl; phosphate; (Ci-Ci2) alkyl optionally substituted with one or more (e.g., 1, 2, 3, or 4) hydroxy, carboxy, carbonyl , acyl , oxy, oxo; or a combination thereof. Suitable specific pendant groups include methyl, ethyl, hydroxypropyl , carboxymethyl , sulfate, phosphate, and an acrylate. For example, the specific pendant group may include (Ci-Ci2) alkoxy optionally substituted with one or more hydroxy.
Specific suitable derivatives of cyclodextrin include, e.g., alpha-cyclodextrin sulfate, beta- cyclodextrin sulfate, gamma-cyclodextrin sulfate, alpha-hydroxypropyl cyclodextrin, beta-hydroxypropyl cyclodextrin, gamma-hydroxypropyl cyclodextrin, alpha- cyclodextrin phosphate, beta-cyclodextrin phosphate, and gamma-cyclodextrin phosphate. Cyclodextrins are starches that have been specially modified by the action of an enzyme to make a water-soluble ring-shaped molecule, capable of holding another, oil -like organic substance in its 'cavity'. Because of this unique property, cyclodextrins may be used to carry all kinds of active ingredients (e.g., drugs, fragrances, flavors, and vitamins) in a wide variety of formulations. Increased stability, water solubility, and controlled release are among the many application benefits. Specifically, cyclodextrins have the benefit of encapsulating a substance, thereby providing protection for the substance. This results in increased shelf-life and a reduced loss of degradation or decomposition. Cyclodextrins are themselves soluble in water, and may greatly increase the solubility of highly water insoluble substances. In addition, cyclodextrins may be used to control the release of a substance. Suitable cyclodextrins include alpha cyclodextrins 6 glucose units) , beta cyclodextrins (7 glucose units, and gamma cyclodextrins (8 glucose units) . Specifically, the cyclodextrin may be hydroxylpropyl beta cyclodextrin, hydroxylproplyl alpha cyclodextrin, or a combination thereof. In addition, the cyclodextrin may optionally be branched.
Suitable cyclodextrins, and derivatives thereof, may be found, e.g., at U.S. Patent No. 5,376,641; U.S. Patent No.5, 229, 370 ; U.S. Patent No.4 , 383 , 992 ; the Cerestar website (http://www.cerestar.com); the Betadexcyclodextrin website
