|Filing Date:||Jun 11, 2009|
|Claims:||1. A therapeutically effective aqueous ophthalmic composition for lowering intraocular pressure comprising: a solution containing 0.1% (w/v) of a compound selected from the group consisting of brimonidine, a salt of brimonidine, wherein the solution further comprises an oxy-chloro preservative and carboxymethylcellulose, wherein the composition has a pH between 7.0-8.0. |
2. The composition of claim 1 which comprises about 0.1% (w/v) of brimonidine tartrate.
3. The composition of claim 1 which comprises 0.1% (w/v) of brimonidine tartrate.
4. The composition of either of claim 3 wherein the carboxymethyl cellulose enhances the solubility of brimonidine tartrate in solution.
5. The composition of claim 3 wherein the oxy-chloro component is Purite.
6. The composition of claim 3 further comprising boric acid.
7. The composition of claim 3 further comprising sodium borate.
8. The composition of claim 3 further comprising hydrochloric acid.
9. The composition of claim 8 wherein the composition has a pH of 7.4-8.0.
