Use of sublingual dexmedetomidine for the treatment of agitation
The present invention discloses a method of treating agitation or the signs of agitation in a subject comprising the sublingual administration of an effective amount of an alpha-2 adrenergic agonist, more particularly Dexmedetomidine, or a pharmaceutically acceptable salt thereof. The method is particularly suitable for the treatment of agitation associated with neurodegenerative and/or neuropsychiatric diseases. The present invention also discloses the sublingual administration of an alpha-2 adrenergic agonist, more particularly Dexmedetomidine or a pharmaceutically acceptable salt thereof at a dose that is effective to treat agitation or the signs of agitation in a subject, but does not cause significant sedation.
1. A method of treating agitation in an agitated subject, said agitated subject having Alzheimer's Disease, consisting of administering to the oral mucosa of said agitated subject one or two single dosage administrations of dexmedetomidine or a pharmaceutically acceptable salt thereof without also causing significant sedation after the administration, wherein the effective amount of dexmedetomidine or the pharmaceutically acceptable salt thereof produces an anti-agitation effect in less than about 60 minutes after administration, wherein each of the one or two single dosages of dexmedetomidine or a pharmaceutically acceptable salt thereof is 60 micrograms; wherein the agitation is not perioperative agitation; and wherein the dexmedetomidine or a pharmaceutically acceptable salt thereof is administered in a solid, water-soluble dosage form.
2. The method according to claim 1 , wherein said dexmedetomidine or a pharmaceutically acceptable salt thereof is administered in a dosage form selected from the group consisting of a film, a wafer, and a tablet.
3. The method according to claim 1 , wherein the agitation is acute agitation.
4. The method according to claim 1 , wherein the agitation is chronic agitation.
5. The method according to claim 1 , wherein the agitation is severe agitation.
6. The method according to claim 1 , wherein the dexmedetomidine or a pharmaceutically acceptable salt thereof is administered sublingually.
7. The method according to claim 6 , wherein the dexmedetomidine or a pharmaceutically acceptable salt thereof is administered sublingually as a film.
8. The method according to claim 7 , wherein the dexmedetomidine or a pharmaceutically acceptable salt thereof is dexmedetomidine hydrochloride.
9. The method according to claim 1 , wherein the dexmedetomidine or a pharmaceutically acceptable salt thereof is administered buccally.
10. The method according to claim 9 , wherein the dexmedetomidine or a pharmaceutically acceptable salt thereof is administered buccally as a film.
11. The method according to claim 10 , wherein the dexmedetomidine or a pharmaceutically acceptable salt thereof is dexmedetomidine hydrochloride.
12. A method of treating agitation in an agitated subject, said agitated subject having Alzheimer's Disease, consisting of administering to the oral mucosa of said agitated subject one or two single dosage administrations of dexmedetomidine or a pharmaceutically acceptable salt thereof without causing significant sedation after the administration, wherein dexmedetomidine or a pharmaceutically acceptable salt thereof produces an anti-agitation effect in less than about 60 minutes after administration, wherein each of the one or two single dosages of dexmedetomidine or a pharmaceutically acceptable salt thereof is administered at a dosage of 60 micrograms; wherein the agitation is not perioperative agitation; and wherein the dexmedetomidine or a pharmaceutically acceptable salt thereof is a film.
13. The method according to claim 12 , wherein the film is administered sublingually.
14. The method according to claim 12 , wherein the film is administered buccally.
