Inventor(s): | Perry; Jason M. (Waltham, MA), Hickey; Magali B. (Waltham, MA), Remenar; Julius F. (Waltham, MA), Vandiver; Jennifer (Waltham, MA) |
Assignee: | ALKERMES PHARMA IRELAND LIMITED (Dublin, IE) |
Application Number: | 13/801,344 |
Patent Claims: | 1. A pharmaceutical composition consisting of: (a) compound A-7: ##STR00026## (b) 1.5-3% benzyl alcohol; (c) 0.1-0.8% polysorbate 20; and (d) an aqueous vehicle
selected from the group consisting of sterile water, bacteriostatic water for injection, sterile saline solution, Ringer's solution, dextrose solution, phosphate buffer, citrate buffer, tartrate buffer, and acetate buffer; wherein the composition forms
an aqueous, flocculated, injectable suspension.
2. The composition of claim 1, wherein (b) and (c) are present at a ratio that results in flocs comprising component (a) wherein the flocs settle to greater than a predetermined sediment bed height, such that components (a), (b) and (c) can be resuspended for injection. 3. The composition of claim 2, wherein the bed height has at least a 20 to 80% higher sediment height compared to a non-flocculated composition after 24 hours of undisturbed sitting. 4. The composition of claim 2, wherein the ratio of (b) to (c) is such that the composition can be injected using a 20 or greater gauge needle. 5. The composition of claim 2, wherein the ratio of (b) to (c) is approximately 4.5 to 1, by weight. 6. The composition of claim 2, wherein the concentration of (a) is approximately 15-35%. 7. An injectable pharmaceutical composition consisting of: (a) approximately 15-35% compound A-7: ##STR00027## (b) approximately 1.5-3% benzyl alcohol; (c) approximately 0.1-0.8% polysorbate 20; and (d) an aqueous carrier selected from the group consisting of sterile water, bacteriostatic water for injection, sterile saline solution, Ringer's solution, dextrose solution, phosphate buffer, citrate buffer, tartrate buffer, and acetate buffer. 8. A method for treating disorders of the central nervous system, comprising administering an effective amount of the composition of claim 1 to an individual in need of such treatment. 9. A pharmaceutical composition consisting of: (a) 15-35% compound A-7: ##STR00028## (b) 1.5-3% benzyl alcohol; (c) 0.1-0.8% polysorbate 20; and (d) an aqueous vehicle selected from the group consisting of sterile water, bacteriostatic water for injection, sterile saline solution, Ringer's solution, dextrose solution, phosphate buffer, citrate buffer, tartrate buffer, and acetate buffer. 10. The composition of claim 1, wherein the sterile saline solution is phosphate-buffered saline. 11. The composition of claim 7, wherein the sterile saline solution is phosphate-buffered saline. 12. The composition of claim 9, wherein the sterile saline solution is phosphate-buffered saline. |
