Small-volume oral transmucosal dosage forms
Small-volume oral transmucosal dosage forms or NanoTabs® comprising a predetermined amount of a pharmaceutically active drug are provided. Exemplary applications include use of the NanoTabs® to administer a drug for the treatment of acute, post-operative or breakthrough pain.
1. A dosage form for oral transmucosal administration to a subject, comprising: from about 0.25 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 wherein after administration of the dosage form to the subject, the dosage form provides a Tmax with a coefficient of variation less than 40%, wherein said Tmax is from about 19.8 minutes to about 60 minutes.
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 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 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 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 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.
7. The dosage form of claim 1 , wherein the oral transmucosal administration is to the sublingual membrane.
8. The dosage form of claim 1 , wherein the administration is to the buccal membrane.
9. 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%.
10. 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%.
11. 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%.
12. The dosage form of claim 1 , wherein the dosage form comprises one or more hydrogel forming excipients.
13. The dosage form of claim 12 , wherein the one or more hydrogel forming excipients is hydroxypropyl methylcellulose.
14. A drug delivery device comprising the dosage form of claim 1 .
15. A dosage form for oral transmucosal administration to a subject, comprising: a bioadhesive dosage form of from about 0.25 micrograms to about 200 micrograms sufentanil with a volume of less than 30 microliters or a mass of less than 30 mg wherein the administration of the dosage form to the subject results in a dose-normalized C max of 2.72+/−0.84 pg/mL per mcg of sufentanil dosed and a T max with a coefficient of variation less than 40%.
16. The dosage form of claim 15 , wherein after administration of the dosage form to the subject, the dosage form provides a T max of from 19.8 minutes to 60 minutes.
