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 (23)

1. A method of treating pain in a subject, comprising administering a dosage form to the oral mucosa of a subject, wherein said dosage form comprises:

from about 5 to about 100 micrograms (mcg) of sufentanil, and a bioadhesive material, wherein:

(i) said bioadhesive material adheres the dosage form to the oral mucosa of said subject during the period of drug delivery;

(ii) said dosage form has a volume of less than 30 microliters or a mass of less than 30 mg; and

(iii) after administration of said dosage form to said subject, said dosage form provides a minimal saliva response and minimal swallowing of sufentanil;

at least 55% of drug delivery of sufentanil occurs via the oral transmucosal route;

said dosage form provides a dose-normalized mean C max of 1.59-2.75 pg/mL per mcg dosed;

said dosage form provides a T max of from about 19.8 minutes to about 60 minutes; and

said dosage form provides a T max with a coefficient of variation of less than 40%.

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

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

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

6. The method according to claim 4 , wherein said dosage form delivers at least 60% of the total amount of sufentanil in said dosage form via the sublingual route.

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

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

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

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

11. The method 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.

12. The method according to claim 11 , wherein said dosage form is a tablet.

13. The method according to claim 1 , wherein said pain is acute pain, breakthrough pain or post-operative pain.

14. The method according to claim 13 , wherein said pain is acute inpatient pain.

15. The method according to claim 13 , wherein said pain is post-operative pain.
