Abstract

Official abstract text for this publication.

Disclosed herein are non-irritating ophthalmic emulsion compositions useful for treating ocular disorders including dry eye. More specifically, the ophthalmic compositions disclosed herein combine a high HLB surfactant and a low HLB surfactant together with an omega-3 fatty acid-containing oil having non-polar aliphatic side chains to form a therapeutic non-irritating eye drop.

First claim

Opening claim text (preview).

I claim: 1. An ophthalmic oil-in-water emulsion composition comprising: an ophthalmically acceptable omega-3 fatty acid-containing oil, wherein the oil is from a botanical source selected from the group consisting of Chia, Kiwifruit, Perilla (shiso or Perilla frutescens), Flax seed, Lingonberry, Camelina, Purslane and Black Raspberry, or is an oil from cold water fish selected from the group consisting of cod liver oil, salmon oil, anchovy oil and tuna oil; a hydrophilic surfactant selected from the group consisting of polyethylene glycol esters of hydrogenated castor oil; a hydrophobic non-co-block surfactant from the group consisting of a polyoxyethylene(2) stearyl ether and a polyoxyethylene(2) oleyl ether; and water; and wherein said oil-in-water emulsion composition has an average particle size less than 1 μm in diameter. 2. The composition according to claim 1 wherein said hydrophilic surfactant and said hydrophobic non-co-block surfactant are present in a ratio of 10.0 to 4.9. 3. The composition according to claim 1 wherein said hydrophilic surfactant and said hydrophobic non-co-block surfactant are present in a ratio of 14.5 to 4.9. 4. The composition according to claim 1 wherein said hydrophilic surfactant and said hydrophobic non-co-block surfactant are present in a ratio of 10.0 to 2.0. 5. The composition according to claim 1 wherein said hydrophilic surfactant and said hydrophobic non-co-block surfactant are present in a ratio of 14.5 to 2.0. 6. The composition according to claim 1 wherein said omega-3 fatty acid-containing oil is from a botanical source selected from the group consisting of Chia, Kiwifruit, Perilla (shiso or Perilla frutescens) Flax seed, Lingonberry, Camelina, Purslane and Black Raspberry. 7. The composition according to claim 1 wherein said omega-3 fatty acid-containing oil is an oil from cold water fish selected from the group consisting of cod liver oil, salmon oil, anchovy oil and tuna oil. 8. The composition according to claim 1 further comprising excipients selected from the group consisting of buffers, microbicides, demulcents, viscosity modifying agents, metal salts, emulsion stabilizers and therapeutic agents. 9. An ophthalmic oil-in-water emulsion composition comprising: at least one ophthalmically acceptable omega-3 fatty acid-containing oil, wherein the oil is from a botanical source selected from the group consisting of Chia, Kiwifruit, Perilla (shiso or Perilla frutescens), Flax seed, Lingonberry, Camelina, Purslane and Black Raspberry, or is an oil from cold water fish selected from the group consisting of cod liver oil, salmon oil, anchovy oil and tuna oil; a hydrophilic surfactant selected from the group consisting of polyethylene glycol esters of hydrogenated castor oil; and a hydrophobic non-co-block surfactant selected from the group consisting of a polyoxyethylene(2) stearyl ether and a polyoxyethylene(2) oleyl ether, wherein the composition has an average particle size of less than 0.6 μm. 10. An ophthalmic oil-in-water emulsion composition consisting essentially of: water; at least one ophthalmically acceptable omega-3 fatty acid-containing oil, wherein the oil is from a botanical source selected from the group consisting of Chia, Kiwifruit, Perilla (shiso or Perilla frutescens), Flax seed, Lingonberry, Camelina, Purslane and Black Raspberry, or is an oil from cold water fish selected from the group consisting of cod liver oil, salmon oil, anchovy oil and tuna oil; a hydrophilic surfactant selected from the group consisting of polyethylene glycol esters of hydrogenated castor oil; and a hydrophobic non-co-block surfactant selected from the group consisting of a polyoxyethylene(2) stearyl ether and a polyoxyethylene(2) oleyl ether, wherein the composition has an average particle size of less than 0.6 μm. 11. An ophthalmic oil-in-water emulsion composition consisting essentially of water, flax seed oil, a polyethylene glycol ester of hydrogenated castor oil, and a polyoxyethylene(2) oleyl ether, wherein the composition has an average particle size of less than 0.6 μm. 12. An ophthalmic oil-in-water emulsion composition consisting essentially of water, flax seed oil, a polyethylene glycol ester of hydrogenated castor oil, a polyoxyethylene(2) stearyl ether or a polyoxyethylene(2) oleyl ether, and an amount of cyclosporine A effective to relieve dry eye symptoms, wherein the composition has an average particle size of less than 0.6 μm.
