Abstract

Compositions, methods and systems for administration of small volume sufentanil-containing drug dosage forms to the oral mucosa of a subject are disclosed.

Claims

1. A dosage form for oral transmucosal administration to a subject, comprising:

from about 5 to about 100 micrograms (mcg) of sufentanil and a bioadhesive material, wherein said bioadhesive material provides for adherence to the oral mucosa of said subject and said dosage form has a volume of less than 30 microliters or a mass of less than 30 mg.

2. The drug dosage form according to claim 1, wherein said dosage form comprises a dose of sufentanil selected from the group consisting of 5 mcg, 10 mcg, 15 mcg, 20 mcg, 30 mcg, 40 mcg, 50 mcg, 60 mcg, 70 mcg, 80 mcg and 100 mcg.

3. The dosage form according to claim 1, wherein said dosage form has a mass of less than 10 mg or a volume of less than 10 μ

l.

4. The dosage form according to claim 1, wherein said oral transmucosal administration is sublingual or buccal administration.

6. The dosage form according to claim 1, wherein the erosion time of said dosage form is from 30 seconds up to a time selected from the group consisting of 5 minutes, 10 minutes, 15 minutes and 30 minutes.

8. The drug dosage form according to claim 4, wherein said dosage form delivers at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 98% or at least 99% of the total amount of sufentanil in said dosage form via the sublingual route.

9. The drug dosage form according to claim 4, wherein a single sublingual administration of said dosage form to a subject results in a bioavailability of greater than 50%.

10. The dosage form according to claim 4, wherein a single sublingual administration of said dosage form to a subject results in a bioavailability of greater than 60%.

11. The dosage form according to claim 4, wherein a single sublingual administration of said dosage form to a subject results in a bioavailability of greater than 70%.

14. The drug dosage form according to claim 4, wherein a single sublingual administration of said dosage form to a subject results in a T_max with a coefficient of variation of less than 40%.

17. The drug dosage form according to claim 4, wherein following repeated sublingual administrations of said dosage form to a subject, the bioavailability is greater than the bioavailability following a single sublingual administration to said subject.

18. The drug dosage form according to claim 4, wherein the difference between the T_max following repeated sublingual administrations and the time of the previous sublingual administration is shorter than the T_max following a single sublingual administration to said subject.

19. The drug dosage form according to claim 4, wherein repeated sublingual administration of said dosage form to a subject results in a T_max with a coefficient of variation of less than 40%.

20. The formulation according to claim 1, wherein said dosage form is selected from the group consisting of a lozenge, a pill, a tablet, a membrane and a strip.

21. The dosage form according to claim 20, wherein said dosage form is a tablet.

22. A single dose applicator (SDA), comprising a dosage form according to claim 1.

64. The use of a single dose applicator (SDA) according to claim 1, for the treatment of pain.

65. The use according to claim 64, wherein said pain is acute pain, breakthrough pain or post-operative pain.

66. The use according to claim 65, wherein said pain is acute inpatient pain.
