Title:	Buccal, polar and non-polar spray or capsule containing drugs for treating pain
Abstract:	Buccal aerosol sprays or capsules using polar and non-polar solvent have now been developed which provide biologically active compounds for rapid absorption through the oral mucosa, resulting in fast onset of effect. The buccal polar compositions of the invention comprise formulation I: aqueous polar solvent, active compound, and optional flavoring agent; formulation II: aqueous polar solvent, active compound, optionally flavoring agent, and propellant; formulation III: non-polar solvent, active compound, and optional flavoring agent; and formulation IV: non-polar solvent, active compound, optional flavoring agent, and propellant.

Application Number:	10/726,625
Claims:	1. A method for administering an effective amount of a pharmacologically active compound to a mammal to provide transmucosal absorption of a pharmacologically effective amount of the active compound through the oral mucosa of the mammal to the systemic circulatory system of the mammal, comprising: spraying the oral mucosa of the mammal with a buccal spray composition, containing a pharmacologically active compound dissolved in a pharmacologically acceptable solvent, comprising in weight percent of the composition: an active compound in an amount of between 0.1 and 25 percent selected from the group consisting of anti-opioid agents, anti-migraine agents, pain control agents, anesthetics, and mixtures thereof; a polar solvent in an amount between 10 and 97 percent; and a propellant in an amount between 2 and 10 percent, wherein said propellant is a C.sub.3 to C.sub.8 hydrocarbon of linear or branched configuration. 2. The method of claim 1, wherein the spray composition further comprises a flavoring agent in an amount between 0.05 and 10 percent by weight of the total composition. 3. The method of claim 2, wherein the polar solvent is present in an amount between 20 and 97 percent by weight of the total composition, the active compound is present in an amount between 0.1 and 15 percent by weight of the total composition, the propellant is present in an amount between 2 and 5 percent by weight of the composition, and the flavoring agent is present in an amount between 0.1 and 5 percent by weight of the total composition. 4. The method of claim 3, wherein the polar solvent is present in an amount between 25 and 97 percent by weight of the total composition, the active compound is present in an amount between 0.2 and 25 percent by weight of the total composition, the propellant is present in an amount between 2 and 4 percent by weight of the composition, and flavoring agent is present in an amount between 0.1 and 2.5 percent by weight of the total composition. 5. The method of claim 1, wherein the polar solvent is selected from the group consisting of polyethyleneglycols having a molecular weight between 400 and 1000, C.sub.2 to C.sub.8 mono- and poly-alcohols, and C.sub.7 to C.sub.18 alcohols of linear or branched configuration. 6. The method of claim 5, wherein the polar solvent comprises aqueous polyethylene glycol. 7. The method of claim 5, wherein the polar solvent comprises aqueous ethanol. 8. The method of claim 1, wherein the active compound is an anti-opioid agent selected from the group consisting of naloxone, nalmefene, naltrexone, cholecystokinin, nociceptin, neuropeptide FF, oxytocin, vasopressin, and mixtures thereof. 9. The method of claim 1, wherein the active compound is an anti-migraine agent selected from the group consisting of frovatriptan, zolmitriptan, rizatriptan, almotriptan, eletriptan, naratriptan, almotriptan, ergotamine, diethylergotamine, sumatriptan, and mixtures thereof. 10. The method of claim 1, wherein the active compound is a pain control agent selected from the group consisting of non-steroidal anti-inflammatory drugs, alfentanil, butorphanol, codeine, dezocine, fentanyl, hydrocodone, hydromorphone, levorphanol, meperidine, methadone, morphine, nalbuphine, oxycodone, oxymorphone, propoxyphene, pentazocine, sufentanil, tramadol, and mixtures thereof. 11. The method of claim 1, wherein the active compound is an anesthetic selected from the group consisting of benzonatate, bupivacaine, desflurane, enflurane, isoflurane, levobupivacaine, lidocaine, mepivacaine, prilocaine, propofol, rapacuronium bromide, ropivacaine, sevoflurane, ketamine, and mixtures thereof. 12. The method of claim 2, wherein the flavoring agent is selected from the group consisting of synthetic or natural oil of peppermint, oil of spearmint, citrus oil, fruit flavors, sweeteners, and mixtures thereof. 13. The method of claim 1, wherein the propellant is selected from the group consisting of propane, N-butane, iso-butane, N-pentane, iso-pentane, neo-pentane, and mixtures thereof.
