Ophthalmic compositions
Provided herein is an ophthalmic composition including a therapeutic active agent and an anti-inflammatory agent, in which the active agent is at least about 0.01% w/v of chlorhexidine, derivatives, or analogues of chlorhexidine, or a pharmaceutically acceptable salt, solvent, hydrate, or polymorph thereof. Methods for treating or preventing ocular disease or infection in a subject in need thereof are also provided. The method may include administering to an eye of a subject an ophthalmic composition including chlorhexidine, derivatives, or analogues of chlorhexidine, or a pharmaceutically acceptable salt, solvent, hydrate, or polymorph thereof, and an anti-inflammatory agent. The chlorhexidine, derivatives, or analogues of chlorhexidine, or a pharmaceutically acceptable salt, solvent, hydrate, or polymorph thereof and the anti-inflammatory agent are present in an amount effective to treat or prevent the ocular disease or infection in a subject in need thereof.
1. A method for treating an ocular disease or infection selected from the group consisting of conjunctivitis and blepharitis in a subject in need thereof comprising administering topically to an eye of the subject an ophthalmic formulation comprising chlorhexidine gluconate in an amount of from 0.05-0.20% w/v, prednisolone acetate, and an ophthalmically acceptable carrier, wherein the chlorhexidine gluconate and prednisolone acetate are combined in the same formulation.
2. The method of claim 1 , wherein the ophthalmic formulation is a solution, suspension, semi-liquid, emulsion, ointment, cream, or foam gel.
3. The method of claim 1 , wherein the ophthalmic formulation is effective to treat infection following an ophthalmic surgery or an ophthalmic procedure.
4. The method of claim 1 , wherein the ophthalmic formulation is administered to the eye in an amount of 50 μL to 80 μL per eye.
5. The method of claim 1 , wherein the ocular disease or infection is of bacterial, mycobacterial, fungal, viral, protozoan, or acanthamoebal origin, or combinations thereof.
6. The method of claim 1 , wherein the chlorhexidine gluconate is at a concentration of 0.1% w/v to 0.2% w/v.
7. The method of claim 1 , wherein the prednisolone acetate is at a concentration of 0.025% w/v to 2.0% w/v.
8. The method of claim 1 , wherein the ophthalmic formulation further comprises a preservative.
9. The method of claim 8 , wherein the preservative comprises benzalkonium chloride, thimerosal, chlorobutanol, methyl paraben, propyl paraben, phenylethyl alcohol, edetate disodium, sorbic acid, and combinations thereof.
10. The method of claim 1 , wherein the ophthalmic formulation further comprises a co-solvent.
11. The method of claim 10 , wherein the co-solvent comprises polysorbate 20, polysorbate 60, polysorbate 80, Pluronic F-68, Pluronic F-84, Pluronic P-103, cyclodextrin, and combinations thereof.
12. The method of claim 11 , wherein the co-solvent is present in an amount of 0.01% w/v to 2.0% w/v.
13. The method of claim 1 , wherein the ophthalmic formulation further comprises a viscosity agent.
14. The method of claim 13 , wherein the viscosity agent comprises polyvinyl alcohol, polyvinyl pyrrolidone, methyl cellulose, hydroxy propyl methylcellulose, hydroxyethyl cellulose, carboxymethyl cellulose, hydroxy propyl cellulose, and combinations thereof.
15. The method of claim 14 , wherein the viscosity agent is present in an amount of 0.01% w/v to 2.0% w/v.
16. The method of claim 1 , wherein the prednisolone acetate is present in an amount of 0.025% w/v to 2.0% w/v.
17. The method of claim 1 , wherein the prednisolone acetate is present in an amount of 0.05% w/v to 1.0% w/v.
18. The method of claim 1 , wherein the prednisolone acetate is 1.0% w/v.
19. The method of claim 1 , wherein the ophthalmic formulation is topically applied by placing one to two drops, or more, in each eye from 1 to 24 times daily until the ocular disease or infection has cleared.
20. The method of claim 19 , wherein the ophthalmic formulation is topically applied by placing one to two drops or more, in each eye from 4 to 18 times daily until the ocular disease or infection has cleared.
21. The method of claim 19 , wherein the ophthalmic formulation is topically applied by placing one to two drops in each eye once or twice daily until the ocular disease or infection has cleared.
22. The method of claim 1 , wherein the formulation further comprises a co-solvent and a viscosity agent.
23. The method of claim 22 , wherein the co-solvent is selected from the group consisting of polysorbate 20, polysorbate 60, polysorbate 80, Pluronic F-68, Pluronic F-84, Pluronic P-103, and cyclodextrin, or a combination thereof.
24. The method of claim 23 , wherein the viscosity agent is selected from the group consisting of polyvinyl alcohol, polyvinyl pyrrolidone, methyl cellulose, hydroxy propyl methylcellulose, hydroxyethyl cellulose, carboxymethyl cellulose, and hydroxy propyl cellulose, or a combination thereof.
25. The method of claim 24 , wherein the prednisolone acetate is at a concentration of 0.025% w/v to 2.0% w/v in the formulation.
26. The method of claim 22 , wherein the formulation comprises polysorbate 80 as a co-solvent and one or both of methyl cellulose and hydroxy propyl methylcellulose as a viscosity agent.
