Therapeutic ophthalmic compositions containing retinal friendly excipients and related methods
First Claim
1. A therapeutic ophthalmic composition useful for injection into a posterior segment of an eye of an individual, comprising a therapeutic component present in an amount effective in providing a desired therapeutic effect to an individual when the composition is administered to the interior of an eye of the individual;
- and an excipient component comprising an excipient agent other than polysorbate 80 or benzyl alcohol, the excipient component present in an amount that is less toxic to retinal pigment epithelial cells relative to an equal amount of an excipient selected from the group consisting of polysorbate 80 and benzyl alcohol.

Abstract
Pharmaceutical compositions suitable for administration into the interior of an eye of a person or animal are described. The present compositions include one or more components which are effective in providing a reduced toxicity relative to existing intraocular ophthalmic compositions. The present compositions include one or more therapeutic agents in amounts effective in providing a desired therapeutic effect when placed in an eye, and one or more retinal friendly excipients that have a reduced toxicity relative to benzyl alcohol or polysorbate 80. In certain compositions, the excipient component of the compositions comprises one or more cyclodextrins or cyclodextrin derivatives. Methods of using the compositions to treat ocular conditions are also described.

a therapeutic component present in an amount effective in providing a desired therapeutic effect to an individual when the composition is administered to the interior of an eye of the individual; - and
an excipient component effective in reducing the toxicity of the ophthalmic composition to retinal pigment epithelial cells of the eye of the individual relative to a second substantially identical composition which comprises at least one excipient selected from the group consisting of polysorbate 80 and benzyl alcohol, when the ophthalmic composition is administered to the interior of the eye of the individual. - View Dependent Claims (13, 19)
