MEDICATED WRAP

Abstract: A device for treating pain in an injured body member a wrap (10) having an interior section (22) which can be loaded with medicament. The wrap (10) also includes at least one inwardly extending nodule (24) adapted to extert pressure on and compress a specific area of the injured member, having acupressure like effect in producing pain relief. The wrap (10) has adjustable means (20, 30) for fastening the wrap (10) around the body member, thereby enabling the wearer to extend a specific amount of pressure on the nodule to achieve the desired results. The combination of restricted movement imparted by the wrap (10) along with the medicament and acupressure affords the wearer more rapid relief than any of the treatments applied separately.

Description: MEDICATED WRAP This is a continuation-in-part of U.S. Application Serial No. 09/561,170, filed April 27, 2000, which claims the benefit of U.S. Provisional Application Serial No. 60/131,857, which was filed April 29, 1999, the disclosures and contents of which are hereby incorporated by reference in their entireties. 1. Field of the Invention The present invention relates to a medical device for relieving pain by simultaneously restricting movement of a body member, applying pain-relieving medicament, and applying pressure to acupressure points. 2. Background of the Invention Many people suffer from sprains, arthritis and other ailments at the joints such as the knees, elbows, wrists as well as neck pain. Often the treatment consists of wraps to stabilize and provide pressure to the joint, sports ointments and creams as well as prescribed and over-the-counter pain medications. Many people suffering from such ailments are reluctant to take pain killing drugs over an extended period of time for fear of obtaining a dependency or simply based upon a general reluctance to take drugs. For these people, the remedies are limited to treatment through ice, heat, wraps and externally applied ointments such as sports creams and the like. The products such as wraps and ointments must be separately purchased. Further, the ointments and creams, if applied underneath a wrap, can stain and soil the wrap making it unsightly for the person to wear in public. Still further, it is known that certain pressure joints near joints, if pressure is applied, can help to reduce and alleviate pain. The wraps and ointments heretofore used do not provide a means to impose an acupressure effect to help reduce pain. Thus there is a clear need in the art to overcome these drawbacks. 3. Summary of The Invention The present invention relates to a device to be disposed around a body portion of a person for treating pain that body portion, wherein the device comprises a wrap having an interior surface for contacting the body portion, and adapted to be disposed around the body portion, said wrap being sufficiently elastic to enable the wrap to be stretched around the body portion to restrict the mobility of the body portion, at least one pad section secured to an interior section of the wrap, each pad section adapted to be loaded with medicament, at least one nodule extending inwardly from the interior surface of the wrap and adapted to contact and exert pressure at a desired specific location on the body portion, and means for tightening and adjustably securing the wrap about the body portion, whereby tightening of the wrap causes medicament to exert pressure on and dispense medicament to the area of plain, and to cause the nodule to exert pressure upon the body portion. The present invention further relates to A method of relieving pain in a body portion comprising extending a flexible wrap around the injured body portion, said wrap having a pad section loaded with medicament and at least one substantially rigid nodule extending inwardly and adapted to contract at least one pre-located acupressure point near the area of the pain, locating the nodule above the acupressure point, and tightening and adjustably securing the wrap such that mobility of the body portion is decreased, pressure is exerted by the nodule on the desired acupressure point, and medicament is dispensed to the are of pain. 4.

Detailed Description of the Invention The invention provides a device for treating pain in an injured body portion which includes a flexible, elastic wrap which can be secured in place around the body portion. The wrap has an interior surface which includes an absorbent pad section designed to be loaded with medicament. The pad section can come preloaded with medicament, in which case the pad is covered by a removable impervious cover element. At least one, and preferably at least two, substantially rigid nodules project inwardly from the wrap and are disposed to contact predetermined areas of the injured member. The nodules are located strategically to provide acupressure-like force against specific acupressure points, which are well known in the art, thereby compressing the point and providing additional pain relief. See, for example, U.S. Patent Nos. 5,792,176, and 5,224,469, which disclose devices for the application of pressure ("acupressure") to selected points on the surface of the body which correspond to acupuncture points identified in Eastern medical practice. The wrap has adjustable fastening means, such as VELCRO hook and loop fasteners, so that the user can stretch the wrap around the injured part and adjust the pressure so as to dispense medicament to the affected area and to select the desired pressure at the acupressure points. Turning to the drawings, Fig. 1 shows a wrap 10 according to one embodiment of the present invention. The wrap 10 has an underside 12 adapted to be positioned against the skin when the wrap is used to treat a joint such as a knee or elbow or it can be of a size to wrap about the trunk of the body to treat the back. The wrap itself includes a main panel 14 connected to a side panel 16 by an elastic margin 18. At the end of the side panel 16 is one member 20 of a hook and pile fastener for securing the wrap 10 about the joint. Disposed on the body 14 is a pad 22 adapted to receive and store medicament for treatment of pain. As shown in Fig. 3, if the pad 22 is loaded with the medicament by the manufacturer, a tearaway cover sheet 26 may be provided by which the user may tear away the protective cover to expose the pad 22 loaded with the medicament. The use of a tear- away cover is conventional technology. The wrap 10 may also include one or more acupressure nodules 24 located to engage pressure points in the joint, muscle or ligament area to apply pressure thereto for the treatment of pain. As shown in Fig. 3, these nodules 24 may be spherical in shape and may be manufactured from a rigid product such as rubber, plastic or the like. With reference to Fig. 2, at the top side 28 of the wrap 10 there is located the other member 30 for the hook and pile fastener for the wrap 10. Accordingly, and with reference to Fig. 4, the user would remove the protective strip or cover 26 to expose the pad 22 preloaded with medicament. The user would then place the pad 22 over, for example, the patella and position the wrap 10 about the knee joint securing it thereto using the members 20,30 of the hook and pile fastener. The elastic margin 18 enables the user to exert pressure by constricting or releasing the pressure imposed by the wrap 10 on the knee joint. In this position, as suggested in Fig. 4, the nodules 24 are disposed to the side and below the patella to exert acupressure effect on the ligaments of the knee joint. Turning to Figs. 5 and 6, a further embodiment of the wrap 10 for use at the wrist is shown. The wrap 10 includes the main panel 14 including the pad 22 to receive the medicament. A hole 32 is provided to pass the thumb when the wrap 10 is disposed about the wrist. Acupressure nodules 24 are provided to exert pressure at desired locations on the wrist. Straps 34a, b include the one member 20 of a hook and pile fastener, the other member 30 (not shown in Figs. 5 and 6) of the hook and pile fastener is disposed on the outside surface of the wrap 10. Turning to Figs. 7-9, an embodiment of the wrap 10 for cervical use is disclosed. The wrap 10 includes the main panel 14 having the pad 22 to retain the medicament. Acupressure nodules 24 are provided to exert pressure at desired locations at the neck. The top side 28 includes the other member 30 of the hook and pile fastener. Straps 34a,b include the member 20 for the hook and pile fastener. Accordingly the wrap 10 is wrapped about the neck placing the pad 22 at the desired location to apply the medicament. At least one nodule is provided on the interior of each wrap, and can be molded, sewn, welded, or otherwise secured to the interior surface of the wrap. The nodules are located on specific portions of the wrap in predetermined areas designed to correspond with known acupressure points for that specific body portion. These acupressure points as well- known and readily identifiable from medical literature, and may be adjacent areas of pain rather than directly on the pain. The nodules should be generally rigid, so that pressure can be applied quite specifically to the desired region of the member in which pain is being suffered. The nodules should have a generally curved surface, so as to not be pointed or have other sharp edges or protrusions that could injure the patient. The specific size of the nodule is not critical, although the area contacting the body should be sufficiently large so as to not create additional pain (e.g. by puncturing or sharply compressing the skin), but should not be so large as to distribute the pressure over a wider area than is necessary. Generally speaking, the area being compressed should be approximately 1/4-3/4 in diameter, depending on the specific area of the body involved. Examples of suitable nodules would be spherical lugs having diameter of 1/4-3/4 inch, preferably about Vi inch, though other shapes and dimensions may be usable depending upon the specific body part. For example, smaller nodules would be used for a wrist wrap, whereas larger nodules might be used for wraps for the knee or back. The nodules can be made from a generally rigid material such as hard rubber, but may have a small amount of resiliency (e.g. less than 10%) which could provide some patient comfort while not compromising the ability of the nodules to exert pressure. The method of pain relief afforded by the invention is implemented by a user either loading the absorbent pad with a medicament or removing the plastic impervious cover to expose pre-loaded medicament. Next, the user (or someone who assists the user) extends the wrap around the injured body portion, locating the nodules above the desired acupressure points. Then the wrap is tightened until the nodules exert pressure at the desired location which is sufficient to substantially compress the desired spot yet not cause additional pain. At this point, the adjustable fastening members are attached to retain the desired pressure. The tightened wrap restricts the mobility of the injured limb, thereby promoting healing. Furthermore, the tightened pressure is sufficient to exert force on the acupressure point and exude medicament from the pad into the area of treatment. These three desired affects combined enable the wearer to heal more quickly in a pain-free environment. After wearing the wrap for a certain period of time, the user may become accustomed to the pressure of the acupressure nodules and desire to increase the pressure, thereby increasing the effectiveness of the nodules. The releasable fastener is then released, the wrap is tightened, and the adjustable fastening members are re-attached. The pad may be any sort of absorbent material, such as sponge, cotton or synthetic fiber, or any other known material which can hold a fluid product. The wrap may be disposable, or may be reusable in which case the pad can be reloaded by the user with medicament prior to each use. The present invention provides a method for pain relief comprising topical administration of therapeutic medicaments using the device disclosed herein. Although topical administration of a medicament avoids, ter alia, many of the drawbacks of oral administration of pain medication, a topical administered medicament must overcome the complex set of diffusion barriers provided by the skin. In general, the skin is highly resistant to permeation by chemicals, including drugs. Although the skin is only a few millimeters thick, the stratum corneum serves as a highly protective barrier against physical, chemical and bacterial penetration. This barrier primarily consists of dead skin cells bound together by certain fatty (lipid) materials. Generally, only drugs that are effective in the body at very low concentrations or that have particular physical properties have been successfully delivered through the skin in therapeutically effective amounts. High molecular weight drugs and drugs which are either charged or highly polar can be difficult to administer transdermally. Accordingly, the rate of penetration of such a topically-applied medicament is dependent upon a number of variables including: the bodily area to which the medicament is applied, the concentration of the active ingredient or ingredients of the applied medicament, and the nature of the vehicle, if any, containing the active ingredient or ingredients of the medicament. The nature of the vehicle selected is defined by, for example, the solubility of the active ingredient and/or active ingredients in the vehicle, rate of release of the active ingredient or active ingredients from the vehicle, the facility with which the vehicle hydrates the stratum corneum layer of the skin and thereby improves permeability of the skin barrier to the active ingredient and/or active ingredients, and the stability of the active ingredient and/or active ingredients in the vehicle. The choice of vehicle for dissolution or suspension of the active ingredient or ingredients is well known in the art (See, for example, Dirk B. Robinson and Howard I. Miabach, Dermatologic Pharmacology in BASIC AND CLINICAL PHARMACOLOGY, 871-87 (Bertram G. Katzung, Ed., Fifth Edition, 1992), which is hereby incorporated by reference in its entirety). The presence of one or more penetration enhancers, described below, in the medicament also affects the rate of diffusion of the one or more active ingredient of the medicament into and across the skin barrier. The pad section may comprise, in various embodiments of the invention, one or more of the following elements: a backing film, a polymer matrix formulated with the active ingredient and/or a compartment filled with a vehicle comprising one or more active ingredients and, in certain embodiments, the vehicle may comprise one or more excipients, one or more membranes that control the rate of release of the active ingredient, pressure-sensitive adhesives that, in certain embodiments, comprise at least one active ingredient and may further comprise at least one excipient, an absorbent material such as, but not limited to, a cotton pad or a sponge, a protective, pressure-sensitive release liner, and a removable impervious cover element. The backing film used in the pad section has an inner surface and an outer surface. The outer surface of the backing film is attached to the inner surface of the wrap. The composition of the backing film is selected according to, inter alia the nature of the active ingredient to be delivered and the length of time the wrap is to remain attached to the body. In certain embodiments, the backing film is constructed of a synthetic polyester to facilitate hydration of the outer surface of the skin. In other embodiments, the backing film is constructed of, as non-limiting examples, polyurethane or polyolefin polymers, and woven or non-woven fibrous materials such as cotton or polyesters and blends thereof. In certain embodiments, the backing film is the inner surface of the wrap. The removable impervious cover element has an inner and outer surface. The edges of the inner surface of the cover element can be attached to the edges of the inner surface of the backing film, thereby forming a space within which the medicament is disposed. The removable impervious cover element is generally constructed of a thin (0.002 - 0.005 inch) impermeable material, which, in one non-limiting example, is a polyester film. The adhesive used for attaching the removable impervious cover element to the backing film is, in one non-limiting example, a silicone-based, pressure-sensitive adhesive release polymer. In certain embodiments of the invention, a membrane, which controls release of the medicament and/or the active ingredient thereof, referred to herein as a rate-controlling membrane is disposed between the removable impervious cover and the medicament. The rate controlling membrane has an inner and an outer surface, wherein the inner surface is in contact with the medicament and the outer surface is the surface to be placed in contact with the skin of the subject patient. The rate-controlling membrane, when present, is generally constructed of, inter alia, a thin (0.001 - 0.003 inch) film of ethylene vinyl acetate or polyethylene. In certain embodiments of the invention, a pressure-sensitive adhesive comprising the one or more active ingredients, is disposed between the backing film and the removable impervious cover, or, when the pad section comprises a rate-controlling membrane, between the backing film and the rate-controlling membrane. In certain embodiments of the invention, the pressure-sensitive adhesive is a hydrophilic adhesive hydrogel, which is formed, in one non-limiting example, from high molecular weight polyvinylpyrrolidone and oligomeric polyethylene oxide. Accordingly, in one embodiment of the invention the medicament is formulated as a hydrogel. Hydrogels are well known in the art as vehicles for the controlled release of drugs. For example, N. A. Peppas, Ed, Hydrogels in Medicine and Pharmacy CRC Press, Inc. (1987) Vol. II, discloses the use of water soluble cellulose ethers such as methylcellulose for controlled release drug delivery systems. In another embodiment of the present invention, the adhesive hydrogel comprises water soluble polymers such as cellulose. Such adhesive hydrogels are described in U.S. Pat. Nos. 5,344,655 and 5,254,338, which are hereby incorporated by reference in their entirety. In a further embodiment, the adhesive hydrogel comprises an aqueous mixture of a radiation crosslinkable water-soluble polymer such as a polymer of N-vinyl-2-pyrrolidone and ethylene oxide and a humectant such as propylene glycol which may be incorporated within the pad section of the medicated wrap of the present invention. The hydrogel may also contain preservatives such as propyl paraben and methyl paraben. Such adhesive hydrogels are described in U.S. Pat. No. 5,405,366, which is hereby incorporated by reference in its entirety. In another embodiment of the present invention, the skin-compatible, pressure-sensitive adhesive hydrogel comprises polyvinyl pyrrolidone and polyvinyl alcohol, a polar plasticizer or humectant such as propylene glycol, water and at least one active ingredient. The composition may also contain cellulose derivatives to increase strength and guar gum to increase tackiness. Such adhesive hydrogels are described in U.S. Pat. No. 4,593,053, which is hereby incorporated by reference in its entirety. In another embodiment, the adhesive hydrogel comprises a water-absorbent resin such as a vinyl acetate-acrylic acid ester copolymer that swells to form a hydrogel upon contact with water. In this instance, the medicament is formulated as a dry powder comprising a gelling agent and at least one active ingredient, where the gelling agent comprises, in one non-limiting example, methylcellulose, a natural gum, glucose, propylparben, methylparaben, and sodium chloride. In other embodiments, the adhesive hydrogels of the present invention further comprise a substituted urea of the formula R-NH-CO-NH 2 , wherein R is hydrogen, hydroxyl, or a lower alkyl having from 1 to 8 carbon atoms selected from the group consisting of methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, hexyl, heptyl and octyl. Preferably, the substituted urea is butylurea. The hydrogels of the present invention may further comprise coloring, fragrance or other pharmaceutically acceptable additives. In certain embodiments, the hydrogels of the present invention comprise 50-80% (by weight) methyl cellulose, 15-25% of a natural gum selected from the xanthan and guar gums, 3-7% glucose, 2-3.5% propylparaben,. 1.5-3% methylparaben, 1-3% sodium chloride and 0.75-3.5% pectin. Such adhesive hydrogels are described in U.S. Pat. Nos. 5,362,497 and 6,214,374 which are hereby incorporated by reference in their entireties. The medicament comprises an active ingredient selected from the following, non-limiting, examples of classes pain relief medications: local anesthetics, non-steroidal anti-inflammatory drugs ("NSAID"), opioids, N-methyl-D-aspartate antagonists ("NMD A"), steroids, corticosteroids, tricyclic antidepressants, and mixtures thereof. In certain embodiments, the medicament may comprise analgesics such as lidocaine, trolamine, salicylate, aspirin creams or any suitable prescriptive or non-prescriptive applied analgesic or anesthetic cream. As used herein, the term "medicament" refers to a composition comprising at least one active ingredient and a pharmaceutically acceptable vehicle suitable for cutaneous application. In certain embodiments, the medicament may further comprise one or more excipients including, but not limited to preservatives, antioxidants, moisturizers, emollients, buffering agents, solubilizing agents, penetration enhancers, skin protectants, and mixtures thereof. As used herein, the term "local anesthetic" means any drug that provides local numbness or analgesia or any drug that provides a regional blockage of nociceptive pathways (afferent and/or efferent). Local anesthetics generally act by reversibly interfering with the generation and propagation of impulses along excitable membranes, particularly along nerve axons. More specifically, local anesthetics bind to membrane receptor proteins associated with sodium channels, thereby reducing or obviating the flux of sodium ions across cell membranes through those channels. The consequent reduction or elimination of the sodium ion current obviates the ability of the cell to generate an action potential, thereby preventing propagation of a nerve impulse (see, for example: Luc M. Hondeghem and Ronald D. Miler Local Anesthetics in BASIC AND CLINICAL PHARMACOLOGY, 363-70 (Bertram G. Katzung, Ed., Fifth Edition, 1992), and William Catterall and Kenneth Mackie Local Anesthetics in GOODMAN & GILMAN' S THE PHARMACOLOGICAL BASIS OF THERAPEUTICS, 331 -47 (Perry B. Molinhoff and Raymond W. Ruddon, Eds., Ninth Edition, 1996), which are hereby incorporated by reference in their entireties). In one embodiment, the medicament comprises at least one local anesthetic as an active ingredient. The local anesthetic can be any local anesthetic known or to be developed. Examples of local anesthetics suitable for use with the invention include: ambucaine, amolanone, amylcaine, benoxinate, benzocaine, betoxycaine, biphenamine, bupivacaine, butacaine, butamben, butanilicaine, butethamine, butoxycaine, carticaine, chloroprocaine, cocaethylene, cocaine, cyclomethycaine, dibucaine, dimethisoquin, dimethocaine, diperodon, dyclonine, ecogonidine, ecogonine, euprocin, fenalcomine, formocaine, hexylcaine, hydroxyteteracaine, isobutyl j-vaminobenzoate, leucinocaine, levoxadrol, lidocaine, mepivacaine, meprylcaine, metabutoxycaine, methyl chloride, myrtecaine, naepaine, octacaine, orthocaine, oxethazaine. parenthoxycaine, phenacaine, phenol, piperocaine, piridocaine, polidocanol, pramoxine, prilocaine, procaine, propanocaine, proparacaine, propipocaine, propoxycaine, pseudococaine, pyrrocaine, ropivacaine, salicyl alcohol, tetracaine, tolycaine, trimecaine, zolamine, pharmaceutically acceptable salts thereof, and mixtures thereof. The amide and ester type local anesthetics are preferred. Amide type local anesthetics are characterized by an amide functionality, while ester type local anesthetics contain an ester functionality. Preferred amide type local anesthetics, include lidocaine, bupivacaine, prilocaine, mepivacaine, etidocaine, ropivacaine, dibucaine, and pharmaceutically acceptable salts thereof and mixtures thereof. Preferred ester type local anesthetics include tetracaine, procaine, benzocaine, chloroprocaine, and pharmaceutically acceptable salts thereof and mixtures thereof. The most preferred local anesthetic is lidocaine. Furthermore, in order to improve the effectiveness and tolerance of the present topically effective therapy, local anesthetics with different pharmacodynamics and pharmacokinetics may be combined in a composition of the invention. A preferred combination of local anesthetics is lidocaine and prilocaine and another preferred combination is lidocaine and tetracaine. In certain embodiments the medicament comprises a local anesthetic at a concentration of from about 0.025% to about 50%, from about 0.05% to about 40%, from about 0.1% to about 35%, from about 0.5% to about 30%, and from about 1% to about 25%, by weight. The medicament of the invention may also comprise as an active ingredient analgesics and anesthetics not typically associated with localized anesthesia, although such compounds can provide a local anesthetic effect. Non-limiting examples of such compounds include non-narcotic analgesics and non-steroidal antinflammatory drugs (NSAID) such as, acetylsalicylic acid, ketoprofen, piroxicam, diclofenac, indomethacin, ketorolac, VIOXX (rofecoxib), CELEBREX (celecoxib), and mixtures thereof. Non-steroidal antim^ammatory drugs generally possess antiinflammatory, antipyretic and analgesic activities. These properties are believed to be mediated through the inhibition of prostaglandin synthesis. More specifically, NSAID compounds have been shown to be inhibitors of either or both of cyclooxygenase I (COX I) or cyclooxygenase II (COX II), which are involved in the synthesis of prostaglandins. Induction of the synthesis of COX II is associated with inflammatory processes and inhibition of COX II is believed to result in the antipyretic and antiinflammatory properties of NSAID compounds. Inhibition of the constitutively-synthesized COX I is believed to be associated with undesirable side effects such as gastric ulcers. Accordingly, selective inhibition of COX II rather than COX I is believed to offer a therapeutic advantage. The medicaments of the present invention may comprise one or more NSAID compounds as an active ingredient selected from the following, non-limiting, chemical classes of analgesic, antipyretic, nonsteroidal antifmflammatory drugs: salicylic acid derivatives, including aspirin, sodium salicylate, choline magnesium trisalicylate, salsalate, diflunisal, salicylsalicylic acid, sulfasalazine, and olsalazin; para-aminophennol derivatives including acetaminophen; indole and indene acetic acids, including indomethacin, sulindac, and etodolac; heteroaryl acetic acids, including tolmetin, diclofenac, and ketorolac; arylpropionic acids, including ibuprofen, naproxen, flurbiprofen, ketoprofen, fenoprofen, and oxaprozin; anthranilic acids (fenamates), including mefenamic acid, and meclofenamic acid; enolic acids, including oxicams (piroxicam, tenoxicam), and pyrazolidinediones (phenylbutazone, oxyphenthartazone); and alkanones, including nabumetone. For a more detailed description of the NSIDs that may be included within the medicaments employed in the present invention, see Paul A. Insel Analgesic-Antipyretic and Antiinflammatory Agents and Drugs Employed in the treatment of Gout in GOODMAN & GILMAN'S THE PHARMACOLOGICAL BASIS OF THERAPEUTICS, 617-57 (Perry B. Molinhoff and Raymond W. Ruddon, Eds., Ninth Edition, 1996), and Glen R. Hanson Analgesic, Antipyretic and Anit-Inflammatory Drugs in REMINGTON: THE SCIENCE AND PRACTICE OF PHARMACY NOL II, 1196-1221 (A. R. Gennaro, Ed. 19 th Ed. 1995) which are hereby incorporated by reference in their entireties. In another embodiment of the invention, the medicament comprises a mixture of a COX II inhibitor and an inhibitor of 5-lipoxygenase for the treatment of pain and/or inflammation. Suitable COX II inhibitors and 5-lipoxygenase inhibitors, as well as combinations thereof are described in U.S. Patent No. 6,136,839, which is hereby incorporated by reference in its entirety. In certain embodiments the medicament comprises NSAID at a concentration of from about 0.0001% to about 50%, from about 0.0002% to about 40%, from about 0.0001% to about 30%, from about 0.001% to about 25 %, from about 0.01% to about 20%, and from about 0.5% to about 15%, by weight. As used herein the term "opioid" means all agonists and atagonists of opioid receptors, such as mu (μ), kappa (K), and delta (δ) opioid receptors and subtypes thereof. For a discussion of opioid receptors and subtypes see Goodman and Gilman 's The Pharmacological Basis of Therapeutics 9th ed. J. G. Har an and L. E. Limird Eds., McGraw-Hill New York: 1996 pp. 521-555, incorporated herein by reference, in its entirety. Opioids are believed to exert their analgesic properties by inhibiting the release of neurotransmitters, including actylcholin, norepinephrine, dopamine, serotonin, and substance P, which are involved in conduction of nerve impulses (for a further description of suitable opioid analgesics for use in the invention, and their pharmacological mode of action, see, Walter L. Way and E. Leong Way, Opioid Analgesics & Antagonists in BASIC AND CLINICAL PHARMACOLOGY, 871-87 (Bertram G. Katzung, Ed., Fifth Edition, 1992), which is hereby incorporated by reference in its entirety). The opioid included within a medicament of the present invention can be any opioid receptor agonist or antagonist known or to be developed.
