Application Number:	15/092,127
Patent Claims:	1. A dosage form for oral transmucosal administration to a subject, comprising: from about 2 micrograms to about 200 micrograms sufentanil, wherein said dosage form is bioadhesive and has a volume of less than 30 microliters or a mass of less than 30 mg. 2. The dosage form of claim 1, wherein the dosage form has a volume of less than 10 microliters or a mass of less than 10 mg. 3. The dosage form of claim 1, wherein after oral administration of the dosage form to the subject, at least 50% of the drug delivery of sufentanil occurs via the oral transmucosal route. 4. The dosage form of claim 3, wherein after oral administration of the dosage form to the subject, at least 55% of the drug delivery of sufentanil occurs via the oral transmucosal route. 5. The dosage form of claim 3, wherein after oral administration of the dosage form to the subject, at least 60% of the drug delivery of sufentanil occurs via the oral transmucosal route. 6. The dosage form of claim 1, wherein after oral administration of the dosage form to the subject, the dosage form provides a Tmax of from about 19.8 minutes to about 60 minutes. 7. The dosage form of claim 1, wherein after oral administration of the dosage form to the subject results in a dose-normalized Cmax of about 2.72+/-0.84 pg/mL per mcg dosed. 8. The dosage form of claim 1, wherein after oral administration of the dosage form to the subject, the dosage form provides a Tmax of from about 19.8 minutes to about 60 minutes and a dose-normalized Cmax of about 2.72+/-0.84 pg/mL per mcg dosed. 9. The dosage form of claim 8, wherein the oral transmucosal administration is to the sublingual membrane. 10. The dosage form of claim 8, wherein the oral administration is to the buccal membrane. 11. The dosage form of claim 1, wherein after oral administration of the dosage form to the subject, the dosage form provides a Tmax with a coefficient of variation less than 40%. 12. The dosage form of claim 1, wherein a single oral transmucosal administration of the dosage form to the subject results in a bioavailability of greater than 65%. 13. The dosage form of claim 1, wherein a single oral transmucosal administration of the dosage form to the subject results in a bioavailability of greater than 75%. 14. The dosage form of claim 1, wherein a single oral transmucosal administration of the dosage form to the subject results in a bioavailability of greater than 80%. 15. The dosage form of claim 1, wherein sufentanil is sufentanil citrate. 16. A drug delivery device comprising the dosage form of claim 1. 17. A dosage form for oral transmucosal administration to a subject, comprising: a bioadhesive dosage form for delivery of sufentanil with a volume of less than 30 microliters or a mass of less than 30 mg wherein the oral administration of the dosage form to the subject results in a dose-normalized Cmax of about 2.72+/-0.84 pg/mL per mcg of sufentanil dosed.
