Abstract

The present disclosure relates to compositions and methods for treating ocular diseases with antibiotics. In particular, the disclosure relates to non-blurring, antibiotic-containing hydrogel compositions that have an extended contact time on the eye and do not interfere with wound healing.

Claims (34)

1. An ocular composition, comprising:

a shear-thinning hydrogel comprising a thiolated hyaluronic acid (HA), wherein the thiolated HA is at a concentration of about 3 to about 8 mg/ml and is covalently crosslinked, and a thiol modification of the thiolated HA is between about 0.05 to about 0.15 μmol thiol/mg; and

an antibiotic at a concentration of about 1 to about 10 mg/ml,

wherein the ocular composition is in the form of an eyedrop.

2. The ocular composition of claim 1 , wherein the thiolated hyaluronic acid is at a concentration of about 3, 4, 5, 6, 7, or 8 mg/ml.

3. The ocular composition of claim 1 , wherein the antibiotic is at a concentration of 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 mg/ml.

4. The ocular composition of claim 1 , wherein the antibiotic has a solubility in water of about 1 mg/ml or greater.

5. The ocular composition of claim 1 , wherein the antibiotic is a fluoroquinolone.

6. The ocular composition of claim 5 , wherein the antibiotic is moxifloxacin or a salt of moxifloxacin.

7. The ocular composition of claim 6 , wherein the antibiotic is moxifloxacin hydrochloride.

8. The ocular composition of claim 5 , wherein the antibiotic is a salt of besifloxacin.

9. The ocular composition of claim 8 , wherein the antibiotic is besifloxacin hydrochloride.

10. The ocular composition of claim 1 , wherein the antibiotic is an aminoglycoside.

11. The ocular composition of claim 10 , wherein the antibiotic is tobramycin.

12. The ocular composition of claim 1 , wherein the thiolated hyaluronic acid is thiolated carboxymethyl hyaluronic acid.

13. The ocular composition of claim 1 , wherein the hydrogel is disulfide crosslinked.

14. The ocular composition of claim 12 , wherein the hydrogel is disulfide crosslinked.

15. An ocular composition, comprising:

a shear-thinning hydrogel comprising thiolated hyaluronic acid (HA), wherein the thiolated HA is at a concentration of about 3 to about 8 mg/ml and is disulfide crosslinked, and a thiol modification of the thiolated HA is between about 0.05 to about 0.15 μmol thiol/mg; and

an antibiotic at a concentration of about 1 to about 10 mg/ml,

wherein upon application, the shear-thinning hydrogel resides on an eye of a patient for between about 30 minutes and about 2 hours, and

wherein the ocular composition is in the form of an eyedrop.

16. The ocular composition of claim 15 , wherein the thiolated hyaluronic acid is at a concentration of 3, 4, 5, 6, 7, or 8 mg/ml.

17. The ocular composition of claim 15 , wherein the antibiotic is at a concentration of 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 mg/ml.

18. The ocular composition of claim 15 , wherein the thiolated hyaluronic acid is at a concentration of about 6.5 to about 8.0 mg/ml.

19. The ocular composition of claim 15 , wherein the antibiotic is a fluoroquinolone.

20. The ocular composition of claim 19 , wherein the antibiotic is a salt of moxifloxacin.

21. The ocular composition of claim 20 , wherein the antibiotic is moxifloxacin hydrochloride.

22. The ocular composition of claim 15 , wherein the thiolated HA is thiolated carboxymethyl HA (CMHA-S).

23. The ocular composition of claim 22 , which upon application remains in contact with an eye surface for at least 30 minutes and up to two hours.

24. The ocular composition of claim 22 , wherein the CMHA-S is at a concentration of about 7 to about 8 mg/ml.

25. The ocular composition of claim 1 , wherein the thiolated HA is at a concentration of about 7 to about 8 mg/ml.

26. The ocular composition of claim 1 , wherein the thiolated HA is thiolated carboxymethyl HA (CMHA-S), and wherein the hydrogel has a viscosity of 0.9-3.6 Pa.s, measured at a shear rate of 2.5 Hz.

27. The ocular composition of claim 22 , wherein the hydrogel has a viscosity of 0.9-3.6 Pa.s, measured at a shear rate of 2.5 Hz.
