Claims for Patent: 8,586,633

Title:Ophthalmologic irrigation solutions and method
Abstract: Solutions for perioperative intraocular application by continuous irrigation during ophthalmologic procedures are provided. These solutions include multiple agents that act to inhibit inflammation, inhibit pain, effect mydriasis (dilation of the pupil), and/or decrease intraocular pressure, wherein the multiple agents are selected to target multiple molecular targets to achieve multiple differing physiologic functions, and are included in dilute concentrations in a balanced salt solution carrier.

Assignee: Omeros Corporation (Seattle, WA)
Application Number:13/420,456
Patent Claims: 1. A composition for use in perioperatively inhibiting ocular inflammation and maintaining mydriasis during an intraocular ophthalmologic procedure, comprising ketorolac and phenylephrine in a physiologic balanced salt solution for intraocular delivery, wherein the ketorolac and the phenylephrine are included at concentrations less than that used for conventional topical or systemic delivery and in a therapeutically effective amount for the maintenance of mydriasis during the procedure and the reduction of postoperative pain when delivered intraocularly during the intraocular ophthalmologic procedure.

2. The composition of claim 1, wherein the ketorolac is included in the solution at a concentration of no more than 100,000 nanomolar and the phenylephrine is included in the solution at a concentration of no more than 500,000 nanomolar.

3. The composition of claim 1, wherein the balanced salt solution liquid irrigation carrier further comprises an adjuvant selected from a cellular energy source, a buffering agent, a free-radical scavenger and mixtures thereof.

4. The composition of claim 3, wherein: the balanced salt solution includes electrolytes comprising from 50 to 500 millimolar sodium ions, from 0.1 to 50 millimolar potassium ions, from 0.1 to 5 millimolar calcium ions, from 0.1 to 5 millimolar magnesium ions, from 50 to 500 millimolar chloride ions, and from 0.1 to 10 millimolar phosphate.

5. The composition of claim 4, wherein the liquid irrigation carrier further comprises bicarbonate at a concentration of from 10 to 50 millimolar; a cellular energy source selected from dextrose and glucose at a concentration of from 1 to 25 millimolar; and a free-radical scavenger comprising glutathione at a concentration of from 0.05 to 5 millimolar.

6. The composition of claim 1, wherein the pH of the irrigation solution is between 5.5 and 8.0.

7. A composition for use during an intraocular ophthalmologic procedure, comprising ketorolac and phenylephrine in a physiologic solution for intraocular delivery, wherein the ketorolac and the phenylephrine are included at concentrations less than that used for conventional topical or systemic delivery and in a therapeutically effective amount for the maintenance of mydriasis during the procedure and the reduction of postoperative pain when delivered intraocularly during the intraocular ophthalmologic procedure.

8. A composition for use during an intraocular ophthalmologic procedure, comprising ketorolac and phenylephrine in a physiologic solution for intraocular delivery, wherein the ketorolac is included at a concentration of no more than 100,000 nanomolar and the phenylephrine is included at a concentration of no more than 500,000 nanomolar.
