Compositions for treating hyperemia
View Patent ↗The present compositions advantageously treat hyperemia with substantially no added irritation to the eye. In one embodiment, the compositions include an ophthalmically acceptable carrier component, a vasoconstrictor component in an amount effective to treat hyperemia when the composition is administered to an eye, and a polyanionic component in an amount effective to provide lubrication to an eye when the compositions are administered to the eye.
1. A composition comprising:
an ophthalmically acceptable carrier component;
a vasoconstrictor component in an amount effective to treat hyperemia when the composition is administered to an eye; and
a polyanionic component in an amount effective to provide lubrication to an eye when the composition is administered to an eye, the composition being a solution.
2. The composition of claim 1 wherein the vasoconstrictor component comprises an alpha-1-adrenergic agonist.
3. The composition of claim 1 wherein the vasoconstrictor component is selected from the group consisting of tetrahydrozoline, ephedrine, naphazoline, phenylephrine, salts thereof and mixtures thereof.
4. The composition of claim 1 wherein the vasoconstrictor component is selected from the group consisting of tetrahydrozoline, salts thereof and mixtures thereof.
5. The composition of claim 1 comprising about 0.001% to about 0.05% (w/v) of the vasoconstrictor component.
6. The composition of claim 1 wherein the polyanionic component is selected from the group consisting of anionic cellulosic derivatives and mixtures thereof.
7. The composition of claim 1 wherein the polyanionic component is selected from the group consisting of carboxy methyl celluloses and mixtures thereof.
8. The composition of claim 1 wherein the polyanionic component is selected from the group consisting of anionic homopolymers and copolymers comprising units of one or more of acrylic acid, methacrylic acid, metal acrylates and metal methacrylates, and mixtures thereof.
9. The composition of claim 1 comprising about 0.1% to about 5% (w/v) of the polyanionic component.
10. The composition of claim 1 wherein the carrier component comprises water.
11. The composition of claim 10 which has a pH in a range of about 6.7 to about 8.0.
12. The composition of claim 1 wherein the carrier component includes at least one of a potassium component and an alkaline earth metal component.
13. The composition of claim 12 wherein the alkaline earth metal component is present and is selected from the group consisting of calcium components, magnesium components and mixtures thereof.
14. The composition of claim 12 wherein the alkaline earth metal component is present in an amount in a range of about 0.001% to about 0.05% (w/v).
15. The composition of claim 1 wherein the carrier component includes at least one of an effective amount of a buffer component and an effective amount of a tonicity adjuster component.
16. The composition of claim 1 which further comprises a chlorine dioxide precursor component in an amount effective in preserving the composition.
17. The composition of claim 1 which is free of an ethylenediaminetetraacetic acid component.
