Title:	Compositions for delivery of therapeutics into the eyes and methods for making and using same
Abstract:	The present invention provides for compositions for administering a therapeutically effective amount of a therapeutic component. The compositions may include an ophthalmically acceptable carrier component; a therapeutically effective amount of a therapeutic component; and a retention component which may be effective to reduce wettability, induce viscosity, increase muco-adhesion, increase meniscus height on a cornea of an eye and/or increase physical apposition to a cornea of an eye of a composition.

Assignee:	Allergan, Inc. (Irvine, CA)
Application Number:	10/911,966
Patent Claims:	1. A topical ophthalmic solution for administering an anti-inflammatory to a human or animal suffering from ophthalmic inflammation, the solution consisting of: water; ketorolac, in a range of 0.01% to 1.0% w/v; a retention component in an amount effective to provide the topical ophthalmic composition with a viscosity greater than human tear fluid wherein the retention component consists of a mixture of medium molecular weight carboxymethyl cellulose and high molecular weight carboxymethyl cellulose wherein the medium and high molecular weight carboxymethyl cellulose have a weight ratio between 0.25 and 4 and is present in an amount of 0.1% to 2.0% w/v; sodium hydroxide and hydrochloric acid to adjust the pH; sodium chloride; a buffer; and having a pH in a range of about 6 to about 8. 2. The topical ophthalmic composition of claim 1 wherein the medium and high molecular weight carboxymethyl cellulose is sodium carboxymethyl cellulose. 3. A topical ophthalmic solution for administering an anti-inflammatory to a human or animal suffering from ophthalmic inflammation, the solution consisting of: water as the carrier component; ketorolac in the amount of 0.01% to 1.0% w/v of the solution; 0.1% to 2.0% w/v of a mixture of medium molecular weight carboxymethyl cellulose and high molecular weight carboxymethyl cellulose wherein the medium and high molecular weight carboxymethyl cellulose have a weight ratio between 0.25 and 4 and are present in an amount of 0.1% to 2.0% w/v; sodium chloride; a buffer; and sodium hydroxide and hydrochloric acid to adjust the solution to a pH in a range of about 6 to about 8. 4. A topical ophthalmic solution for treatment of pain and inflammation for ocular administration to a human consisting of: water; ketorolac in an amount of 0.01% to 1.0% w/v of the solution; 0.1% to 2.0% w/v of a mixture of medium molecular weight carboxymethyl cellulose and high molecular weight carboxymethyl cellulose wherein the medium and high molecular weight carboxymethyl cellulose have a weight ratio between 0.25 and 4 and is present in an amount of 0.1% to 2.0% w/v; sodium chloride; a buffer; and sodium hydroxide and hydrochloric acid to adjust the solution to a pH in a range of about 6 to about 8. 5. The solution of claim 3 wherein the sodium hydroxide and hydrochloric acid are 1 N. 6. The topical ophthalmic solution of claim 4 wherein the solution has a pH of about 6.8.
