Abstract

The presently described technology provides compositions comprising aryl carboxylic acids chemically conjugated to hydrocodone (morphinan-6-one, 4,5-alpha-epoxy-3-methoxy-17-methyl) to form novel prodrugs/compositions of hydrocodone, including benzoates and heteroaryl carboxylic acids, which have a decreased potential for abuse of hydrocodone. The present technology also provides methods of treating patients, pharmaceutical kits and methods of synthesizing conjugates of the present technology.

Claims (28)

1. A composition comprising a conjugate, wherein the conjugate is nicotinate-hydrocodone (nicotinate-HC) having the following structure:

2. The composition of claim 1 , wherein the conjugate is used to treat narcotic or opioid abuse; to reduce narcotic or opioid withdrawal; to treat moderate to severe pain; to reduce oral, intranasal or intravenous drug abuse; or to provide oral, intranasal or parenteral drug abuse resistance.

3. The composition of claim 1 , wherein the conjugate exhibits an improved AUC and rate of release over time when compared to unconjugated hydrocodone over the same time period; exhibits less variability in the oral PK profile when compared to unconjugated hydrocodone; or has reduced side effects when compared with unconjugated hydrocodone.

4. The composition of claim 1 , wherein the conjugate is provided in a dosage form selected from the group consisting of: a tablet, a capsule, a caplet, a suppository, a troche, a lozenge, an oral powder, a solution, an oral film, a thin strip, a slurry, and a suspension.

5. The composition of claim 1 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC when compared to unconjugated hydrocodone.

6. The composition of claim 1 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC and C max when compared to an equivalent molar amount of unconjugated hydrocodone.

7. The composition of claim 1 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC and a lower C max when compared to an equivalent molar amount of unconjugated hydrocodone.

8. A composition comprising a conjugate, wherein the conjugate is 2-aminobenzoate-hydrocodone (2-ABz-HC) having the following structure:

9. The composition of claim 8 , wherein the conjugate is used to treat narcotic or opioid abuse; to reduce narcotic or opioid withdrawal; to treat moderate to severe pain; to reduce oral, intranasal or intravenous drug abuse; or to provide oral, intranasal or parenteral drug abuse resistance.

10. The composition of claim 8 , wherein the conjugate exhibits an improved AUC and rate of release over time when compared to unconjugated hydrocodone over the same time period; exhibits less variability in the oral PK profile when compared to unconjugated hydrocodone; or has reduced side effects when compared with unconjugated hydrocodone.

11. The composition of claim 8 , wherein the conjugate is provided in a dosage form selected from the group consisting of: a tablet, a capsule, a caplet, a suppository, a troche, a lozenge, an oral powder, a solution, an oral film, a thin strip, a slurry, and a suspension.

12. The composition of claim 8 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC when compared to unconjugated hydrocodone.

13. The composition of claim 8 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC and C max when compared to an equivalent molar amount of unconjugated hydrocodone.

14. The composition of claim 8 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC and a lower C max when compared to an equivalent molar amount of unconjugated hydrocodone.

15. A composition comprising a conjugate, wherein the conjugate is 3-hydroxybenzoate-hydrocodone (3-OH-Bz-HC) having the following structure:

16. The composition of claim 15 , wherein the conjugate is used to treat narcotic or opioid abuse; to reduce narcotic or opioid withdrawal; to treat moderate to severe pain; to reduce oral, intranasal or intravenous drug abuse; or to provide oral, intranasal or parenteral drug abuse resistance.

17. The composition of claim 15 , wherein the conjugate exhibits an improved AUC and rate of release over time when compared to unconjugated hydrocodone over the same time period; exhibits less variability in the oral PK profile when compared to unconjugated hydrocodone; or has reduced side effects when compared with unconjugated hydrocodone.

18. The composition of claim 15 , wherein the conjugate is provided in a dosage form selected from the group consisting of: a tablet, a capsule, a caplet, a suppository, a troche, a lozenge, an oral powder, a solution, an oral film, a thin strip, a slurry, and a suspension.

19. The composition of claim 15 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC when compared to unconjugated hydrocodone.

20. The composition of claim 15 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC and C max when compared to an equivalent molar amount of unconjugated hydrocodone.

21. The composition of claim 15 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC and a lower C max when compared to an equivalent molar amount of unconjugated hydrocodone.

22. A composition comprising a conjugate, wherein the conjugate is 4-methoxybenzoate-hydrocodone (4-MeO-Bz-HC) having the following structure:

23. The composition of claim 22 , wherein the conjugate is used to treat narcotic or opioid abuse; to reduce narcotic or opioid withdrawal; to treat moderate to severe pain; to reduce oral, intranasal or intravenous drug abuse; or to provide oral, intranasal or parenteral drug abuse resistance.

24. The composition of claim 22 , wherein the conjugate exhibits an improved AUC and rate of release over time when compared to unconjugated hydrocodone over the same time period; exhibits less variability in the oral PK profile when compared to unconjugated hydrocodone; or has reduced side effects when compared with unconjugated hydrocodone.

25. The composition of claim 22 , wherein the conjugate is provided in a dosage form selected from the group consisting of: a tablet, a capsule, a caplet, a suppository, a troche, a lozenge, an oral powder, a solution, an oral film, a thin strip, a slurry, and a suspension.

26. The composition of claim 22 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC when compared to unconjugated hydrocodone.

27. The composition of claim 22 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC and C max when compared to an equivalent molar amount of unconjugated hydrocodone.

28. The composition of claim 22 , wherein the conjugate is provided in an amount sufficient to provide a therapeutically bioequivalent AUC and a lower C max when compared to an equivalent molar amount of unconjugated hydrocodone.
