Definitions

  • the present invention relates to the management of chronic pain without requiring administration of narcotics, or by synergizing with narcotics to allow for a lower effective narcotic dose.
  • the invention also relates to self-management of pain on an outpatient basis.
  • Ketamine ((2-(2-chlorophenyl)-2-(methylamino)-cyclohexanone) is a general anesthetic used by anesthesiologists, veterinarians, and researchers. Usually, ketamine is administered intramuscularly (i.m.) or intravenously (i.v.) for induction of anesthesia. Presently, only ketamine for injection is available for administration (Physician's Desk Reference) . Nasal administration of ketamine, in one instance with midazolam, for an ophthalmic procedure, and prior to elective surgery in healthy children, has been reported (Louon et al., 1993, Br. J. Ophthalmol. 77:529-530; Weksler et al., 1 993, Can. J. Anaesthesia 40:1 19-121 ).
  • Ketamine has also been known to have analgesic properties (Domino et al., 1965, Clin. Pharmacol. Ther. 6:279); analgesia can be achieved with subanesthetic doses of ketamine (Bovill, 1971 , Br. J. Anaesth. 43:496; Sadove et al., 1 971 , Anesth. Analg. 50:452-457) .
  • the drug is administered by various routes, including i.v., i.m., caudal, intrathecal, and subcutaneous (s.c).
  • Subcutaneous administration of ketamine has been used to treat pain following surgery and associated with terminal cancer (see, e.g. , Oshima et al., 1990, Can.
  • Ketamine hydrochloride administered via a subcutaneous cannula was reported to successfully treat phantom limb pain (Stannard and Porter, 1993, Pain 54:227-230) .
  • the first line of treatment usually involves administration of ⁇ -opioid agonists, e.g. , narcotics such as morphine (see, e.g. , Anderson and Brill, 1 992, Semin. Anesth. 1 1 : 1 58-171 ) .
  • narcotics such as morphine
  • morphine see, e.g. , Anderson and Brill, 1 992, Semin. Anesth. 1 1 : 1 58-171
  • Ineffective pain management is a consequence of lack of training, and of fear of narcotics on the part of patients, the medical personnel, and society in general. Children, because of their natural reticence and budding communication skills combined with a greater fear of over-administering "dangerous" narcotics particularly suffer from under treatment for pain.
  • NMDA N-methyl-D-aspartate
  • pain management involves administration of a plethora of drugs, such as narcotics, agonist-antagonist agents, butorphanols, benzodiazepines, GABA stimulators, barbiturates, barbiturate-like drugs, orally, e.g., in a pill or liquid formulation, or by i.v. or i.m. injection.
  • drugs such as narcotics, agonist-antagonist agents, butorphanols, benzodiazepines, GABA stimulators, barbiturates, barbiturate-like drugs, orally, e.g., in a pill or liquid formulation, or by i.v. or i.m. injection.
  • Opioid agonists and antagonists may be combined.
  • a combination of drugs can have offsetting effects. More problematic is the possibility of adverse side effects, particularly gastric distress that accompanies oral administration, or the fear that injections can inspire.
  • a patient suffering from chronic pain will require medication to control stomach and other gastric problems as a result of oral administration of drugs.
  • Alternatives to oral self-administration for most of the analgesic and sedative medications for the treatment of chronic pain are not common, can be cumbersome (e.g., i.v. or s.c. administration requires use of a cannula or needle), and generally require medical training.
  • U.S. Patent No. 4,671 ,953 describes the administration of sedative, analgesic or sedative drugs in a candy matrix, such that the drug enters the bloodstream through the oral mucosal membranes.
  • this method suffers from the disadvantage that a sedated patient may fall asleep with the candy remaining in his or her mouth, which can result in choking.
  • administration of the candy must be medically supervised.
  • the candy is simply unsuitable for everyday use, as sucking on a lollipop is an unseemly practice for an employee or business person.
  • administration is under the control of the patient suffering from pain, i.e. , on an outpatient basis, the potential for overdosing or abuse exists, particularly with respect to narcotics.
  • ketamine can surprisingly be administered nasally to alleviate pain safely and effectively, in conjunction with or independently of other pain management regimens.
  • the present invention is broadly directed to a method for treating pain in a subject comprising administering via a transmucosal route a dose of ketamine effective to alleviate pain to a subject suffering from pain.
  • administration of ketamine can be via transbuccal, sublingual, vaginal, and rectal routes.
  • the pain-relieving effects of the present invention can be accomplished by administration via oral administration (via the gastrointestinal tract, rather than the oral-pharyngeal mucosa).
  • the present invention provides for pulmonary administration of ketamine by inhalation.
  • the invention provides an effective pain-relieving dose of ketamine by transdermal administration.
  • Administration of an analgesic dose of ketamine advantageously allows for patient self administration of the drug, which provides for pain management on an outpatient basis.
  • ketamine administration via transmucosal and transdermal delivery are generally socially acceptable.
  • Transmucosal administration of ketamine is rapid, allowing for fast action of the drug.
  • both transmucosal and transdermal administration are easily accomplished by a non-medically trained patient.
  • the present invention is based, in part, on the discovery that high levels of analgesia can be achieved with small doses of ketamine, particularly ketamine administered by a transmucosal route (e.g., transbuccal, sublingual, vaginal, and rectal), or by a transdermal route.
  • transmucosal route e.g., transbuccal, sublingual, vaginal, and rectal

  • polymeric materials can be used (see Medical Applications of Controlled Release, Langer and Wise (eds.), CRC Pres., Boca Raton, Florida (1974); Controlled Drug Bioavailability, Drug Product Design and Performance, Smolen and Ball (eds.), Wiley, New York ( 1984); Ranger and Peppas, 1983, J. Macromol. Sci. Rev. Macromol. Chem. 23:61 ; see also Levy et al., 1985, Science 228: 190; During et al., 1989, Ann. Neurol. 25:351 ; Howard et al., 1989, J. Neurosurg. 71 : 105).
  • Ketamine (10 mg/cc) drip was administered i.v. over one hour, for a total dose of 40 mg ketamine. This resulted in reduction of the pain level by a factor of 2 (from #20 to about #10-1 2) as subjectively evaluated by the patient. About 1 hour after ketamine infusion was discontinued, the patient reported that the level of pain had increased to about #1 5, and thereafter rapidly to its previous level. The patient continued to take the other pain medications without effect.
  • a 5 ml bottle containing 100 mg/ml ketamine solution was prepared.
  • a single spray from the bottle delivered approximately 1 /6 ml of solution, i.e. , 16 mg of ketamine.
  • the patient was instructed to self- administer 1 -2 sprays from the bottle for severe pain.
  • the nasal spray bottle was prepared in order to provide sustainable pain medication on an outpatient basis.
  • the patient has demonstrated remarkable pain management with nasal administration of ketamine.
  • Nasal ketamine has been particulariy effective for control of breakthrough pain.
  • the patient has decreased the amount of the other pain medications.

Abstract

Procédé de gestion de la douleur qui ne nécessite pas l'administration de narcotiques ou en permet la réduction, et de gestion personnelle de la douleur sur la base de consultations externes. La présente invention concerne donc, de manière générale, un procédé de traitement de la douleur chez un sujet, qui consiste à administrer à travers les muqueuses, par voie percutanée ou orale une dose de kétamine efficace pour soulager la douleur chez un sujet qui y est en proie. Le présente invention concerne en outre un procédé de traitement synergique de la douleur chez un sujet, qui consiste à administrer, par une voie quelconque, une dose de kétamine efficace pour permettre la réduction des substances administrées dans le cadre de la thérapie de lutte contre la douleur en cours, ou pour réduire la douleur (améliorer le niveau de soulagement de la douleur), ou les deux. L'administration par les muqueuses, percutanée ou orale de kétamine permet avantageusement au patient de s'administrer lui-même le médicament, ce qui conduit à une gestion de la douleur sur la base de consultations externes. De plus, l'administration de kétamine par des dispositifs percutanés (suppositoires, pastilles, timbres buccaux) est en général socialement acceptable. Dans un exemple spécifique, un patient souffrant de douleurs rebelles de la vessie a pu lutter contre l'apparition des douleurs par administration à travers les muqueuses (nasale) d'environ 16 à environ 32 mg de kétamine par dose.
