Assignee:	Alcon Pharmacueticals Ltd. (Fribourg, CH)
Application Number:	13/745,062
Patent Claims:	1. An aqueous ophthalmic composition, comprising: 0.4 w/v %--less than 1.0 w/v % moxifloxacin; sodium chloride in an amount that provides a weight/volume ratio of sodium chloride to moxifloxacin that is between 1.0 and 1.7; 0.02 w/v %--less than 0.1 w/v % surfactant, wherein the surfactant comprises a polyether alcohol; 0.2 w/v %--less than 1 w/v % total of a borate and a polyol; 0.3 w/v %--less than 1.2 w/v % xanthan gum; and water; wherein the composition has a turbidity less than 13 NTU. 2. The composition of claim 1 wherein the total concentration of the borate and the polyol is at least 0.5 w/v % but less than 0.7 w/v %. 3. The composition of claim 1 wherein the concentration of the surfactant is at least 0.04 w/v % but less than 0.1 w/v %. 4. The composition of claim 1 wherein the composition is packaged in an eye drop container. 5. The composition of claim 1 wherein the polyol includes sorbitol and the borate includes boric acid. 6. The composition of claim 1 wherein the composition has a turbidity less than 10 NTU. 7. The composition of claim 1 wherein the composition has a pH of 6.4 to 7.5. 8. An aqueous pharmaceutical composition, comprising: 0.4 w/v %--less than 1.0 w/v % moxifloxacin; sodium chloride in an amount that provides a weight/volume ratio of sodium chloride to moxifloxacin that is between 1.1 and 1.4; 0.04 w/v %--less than 0.07 w/v % surfactant, wherein the surfactant comprises an alkyl aryl polyether alcohol; 0.5 w/v %--less than 1 w/v % total of a borate and a polyol; 0.6 w/v %--less than 0.75 w/v % xanthan gum; and water; wherein the composition has a turbidity less than 10 NTU and a pH of 6.7-7.5. 9. The composition of claim 8 wherein the composition is packaged in an eye drop container. 10. The composition of claim 8 wherein the polyol includes sorbitol and the borate includes boric acid. 11. An aqueous pharmaceutical composition, consisting essentially of: 0.4 w/v %--less than 1.0 w/v % moxifloxacin; sodium chloride in an amount that provides a weight/volume ratio of sodium chloride to moxifloxacin that is between 1.1 and 1.4; 0.04 w/v %--less than 0.07 w/v % surfactant, wherein the surfactant comprises an alkyl aryl polyether alcohol; 0.5 w/v %--less than 1 w/v % total of a borate and a polyol; 0.6 w/v %--less than 0.75 w/v % xanthan gum; and water; wherein the composition has a turbidity less than 10 NTU, a pH of 6.7-7.5 and an osmolality of 200 to 400 mOsm/kg.
