Application Number:	US18/216,890
Patent Claims:	1. A method of treating an agitation of a human subject using an oromucosal formulation of dexmedetomidine, the method comprising: administering an initial dose of the oromucosal formulation of dexmedetomidine or a pharmaceutically acceptable salt thereof to the human subject, wherein the initial dose is 60 mcg, 80 mcg, 90 mcg, 120 mcg, or 180 mcg of dexmedetomidine; and, after at least two hours, administering a second dose of the oromucosal formulation of dexmedetomidine or a pharmaceutically acceptable salt thereof to the human subject, wherein the agitation of the human subject is persistent, and wherein the second dose is 40 mcg, 60 mcg, 80 mcg, or 90 mcg of dexmedetomidine, and wherein the human subject has a corrected OT interval using Fridericia's correction method (QTcF) of less than 470 msec. 2. The method of claim 1, wherein the initial dose is 60 mcg, 80 mcg, or 90 mcg. 3. The method of claim 2, wherein the second dose is 40 mcg, 60 mcg, or 80 mcg. 4. The method of claim 1, wherein the initial dose is 120 mcg or 180 mcg. 5. The method of claim 4, wherein the second dose is 60 mcg. 6. The method of claim 4, wherein the second dose is 40 mcg, 60 mcg, or 80 mcg. 7. The method of claim 1, wherein the second dose is 40 mcg, 60 mcg, or 80 mcg. 8. The method of claim 1, wherein the second dose is 60 mcg or 90 meg. 9. The method of claim 1, wherein the second dose is 60 mcg. 10. The method of claim 1, wherein the initial dose is 120 mcg and the second dose is 60 mcg. 11. The method of claim 1, wherein the initial dose is 180 mcg and the second dose is 90 mcg. 12. The method of claim 1, wherein the second dose is administered to a subject having a change in PEC score of less than or equal to 40% following the initial dose. 13. The method of claim 1, wherein the second dose is administered to a subject having a systolic/diastolic blood pressure greater than 90/60, and a heart rate greater than 60 bpm. 14. The method of claim 1, wherein the human subject has a QTcF of less than 450 msec. 15. A method of treating an agitation of a human subject using an oromucosal formulation of dexmedetomidine, the method comprising: administering an initial dose of the oromucosal formulation of dexmedetomidine or a pharmaceutically acceptable salt thereof to the human subject, wherein the initial dose is 120 mcg of dexmedetomidine; and, after at least two hours, administering a second dose of the oromucosal formulation of dexmedetomidine or a pharmaceutically acceptable salt thereof to the human subject, wherein the second dose is 60 mcg of dexmedetomidine, and wherein the human subject has a corrected QT interval using Fridericia's correction method (QTcF) of less than 470 msec. 16. The method of claim 15, wherein the human subject has a QTcF of less than 450 msec. 17. A method of treating an agitation of a human subject using an oromucosal formulation of dexmedetomidine, the method comprising: administering an initial dose of the oromucosal formulation of dexmedetomidine or a pharmaceutically acceptable salt thereof to the human subject, wherein the initial dose is 180 mcg of dexmedetomidine; and, after at least two hours, administering a second dose of the oromucosal formulation of dexmedetomidine or a pharmaceutically acceptable salt thereof to the human subject, wherein the second dose is 90 mcg of dexmedetomidine, and wherein the human subject has a corrected OT interval using Fridericia's correction method (QTcF) of less than 470 msec. 18. The method of claim 17, wherein the human subject has a QTcF of less than 450 msec.
