BROMFENAC OPHTHALMIC FORMULATIONS AND METHODS OF USE
The present invention discloses a stability enhanced aqueous liquid preparation containing 2-amino-3-(4-bromobenzoyl)phenylacetic acid or its pharmacologically acceptable salt or a hydrate thereof, an alkyl aryl polyether alcohol type polymer such as tyloxapol, or a polyethylene glycol fatty acid ester such as polyethylene glycol monostearate. The present invention further discloses new bromfenac ophthalmic compositions which can potentially treat a broader patient population, and have greater stability properties, and may require a lower concentration or less doses of bromfenac then previously known bromfenac compositions. The present invention further comprises a method for treating inflammation and/or pain of the eye in a patient which method comprises topical application to the eye of a patient in need thereof of a therapeutically effective amount of a topical ophthalmic composition comprising bromfenac at a concentration of about 0.05% w/v to about 0.24% w/v.

15 . The method of claim 13 , wherein said inflammation in the eye is caused by surgical trauma.
16 . The method of claim 15 , wherein said surgical trauma is the result of cataract surgery.
17 . The method of claim 15 , wherein said surgical trauma is the result of a refractive eye surgery.
18 . The method of claim 17 , wherein said refractive eye surgery is photorefractive keratectomy (PRK) or laser epithelial keratomileusis (LASEK) refractive eye surgery.
19 . A method of treating an eye wherein its normal condition has been disrupted or changed comprising:
administering the formulation of claim 1 to said eye one time daily.
20 . The method of claim 19 , wherein the disruption or change is due to blepharitis, conjunctivitis, scleritis, or postoperative inflammation.
21 . The method of claim 19 , wherein said formulation is administered to treat or alleviate pain and/or inflammation associated with said disrupted or changed condition of the eye.
22 . A method for treating a patient for pain and/or inflammation associated with eye surgery comprising:
pre-dosing the patient for up to 48 hours before the eye surgery with the formulation of claim 1;
wherein the formulation is applied once daily; and
applying said formulation once daily post surgery for about 14 days or until condition has been alleviated.
23 . The method of claim 22 , wherein said eye surgery is cataract surgery.
24 . The method of claim 22 , wherein said eye surgery is any refractive eye surgery.
25 . The method of claim 24 , wherein said refractive surgery is photorefractive keratectomy (PRK) surgery or laser epithelial keratomileusis (LASEK) refractive eye surgery.
26 . The method of claim 22 , wherein the pain and/or inflammation is due to postoperative eye surgery.
27 . The method of claim 9 , wherein said formulation is administered twice per day.
28 . The method of claim 27 , wherein the ocular disease, injury, or disorder is caused by surgery, physical damage to the eye, glaucoma, diabetic retinopathy, and/or macular degeneration.
29 . The method of claim 27 , wherein the ocular disease, injury, or disorder is one which results in vascular leakage in the eye or inflammation in the eye.
30 . The method of claim 29 , wherein the inflammation in the eye is caused by surgical trauma; dry eye; allergic, viral, or bacterial conjunctivitis; injury from a chemical, radiation, or thermal burn; and/or penetration of a foreign body.
31 . The method of claim 30 , wherein the inflammation in the eye is caused by allergic, viral, or bacterial conjunctivitis.
32 . The method of claim 30 , wherein the inflammation in the eye is caused by surgical trauma.
33 . The method of claim 32 , wherein said surgical trauma is the result of cataract surgery.
34 . The method of claim 32 , wherein said surgical trauma is the result of refractive eye surgery.
35 . The method of claim 34 , wherein said refractive eye surgery is photorefractive keratectomy (PRK) or laser epithelial keratomileusis (LASEK) refractive eye surgery.
