Patent Claims: |
1. A physically stable pharmaceutical composition comprising: 0.4 wt/wt % to 1.0 wt/wt % aprepitant; 13 wt/wt % to 15 wt/wt % egg yolk lecithin; 9 wt/wt % to 10 wt/wt %
soybean oil; and a pH modifier, wherein the pH modifier is sodium oleate; wherein the pH of the composition ranges from 7.5 to 9.0, wherein the ratio of egg yolk lecithin to aprepitant (wt %:wt %) ranges from about 18:1 to 22:1.
2. The composition according to claim 1, wherein the composition comprises 0.7 wt/wt % aprepitant. 3. The composition according to claim 1, wherein the composition comprises 14 wt/wt % egg yolk lecithin. 4. The composition according to claim 1, wherein the composition further comprises 3 wt/wt % to 8 wt/wt % sucrose. 5. The composition according to claim 1, wherein the composition further comprises 5 wt/wt % sucrose. 6. The composition according to claim 1, wherein the composition further comprises 2 wt/wt % to 6 wt/wt % ethanol. 7. The composition according to claim 1, wherein the composition further comprises less than 6 wt/wt % ethanol. 8. A physically stable pharmaceutical composition suitable for intravenous administration comprising: 0.7 wt/wt % aprepitant; 14 wt/wt % egg yolk lecithin; 9 wt/wt % to 10 wt/wt % soybean oil; and a pH modifier, wherein the pH modifier is sodium oleate; wherein the pH of the composition ranges from 7.5 to 9.0. 9. The composition according to claim 8, wherein the composition further comprises 5 wt/wt % sucrose. 10. The composition according to claim 8, wherein the composition further comprises 2 wt/wt % to 6 wt/wt % ethanol. 11. The composition according to claim 8, wherein the composition further comprises less than 4 wt/wt % ethanol. 12. A method for treating nausea and vomiting in a subject in need thereof comprising administering to the subject the pharmaceutical composition according to claim 1. 13. The method according to claim 12, wherein the nausea and vomiting is chemotherapy induced nausea and vomiting. 14. The method according to claim 13, wherein the chemotherapy induced nausea and vomiting is in response to highly emetic chemotherapy. 15. The method according to claim 13, wherein the chemotherapy induced nausea and vomiting is in response to moderately emetic chemotherapy. 16. The method according to claim 12, wherein the administering is intravenous. 17. A method for treating nausea and vomiting in a subject in need thereof comprising administering to the subject the pharmaceutical composition according to claim 8. 18. The method according to claim 17, wherein the nausea and vomiting is chemotherapy induced nausea and vomiting. 19. The method according to claim 18, wherein the chemotherapy induced nausea and vomiting is in response to highly emetic chemotherapy. 20. The method according to claim 18, wherein the chemotherapy induced nausea and vomiting is in response to moderately emetic chemotherapy. 21. The method according to claim 17, wherein the administering is intravenous. |
