The present disclosure relates to pharmaceutical compositions comprising a gonadotropin-releasing hormone (GnRH) antagonist and methods of preparing and using such compositions. The disclosure also relates to methods of facilitating release of a GnRH antagonist from a pharmaceutical composition.
1. A pharmaceutical composition comprising:
from about 20 to about 60% by weight of sodium 4-((R)-2-[5-(2-fluoro-3-methoxy-phenyl)-3-(2-fluoro-6-trifluoromethyl-benzyl)-4-methyl-2,6-dioxo-3,6-dihydro-2H-pyrimidin-1-yl]-1-phenyl-ethylamino)butanoate (“elagolix sodium”);
from about 10 to about 30% by weight of sodium carbonate; and
a first filler in an amount from about 20% to about 50% by weight and a second filler in an amount from about 1% to about 20% by weight,
wherein the first filler is mannitol and the second filler is pregelatinized starch,
wherein each weight percentage is on the basis of the total weight of the pharmaceutical composition, and
wherein said composition is in the form of a stable immediate release tablet.
2. The pharmaceutical composition of claim 1 , wherein the first filler is present in the pharmaceutical composition in an amount of from about 25% to about 40% by weight.
3. The pharmaceutical composition of claim 1 , wherein the first filler is present in the pharmaceutical composition in an amount of about 32% by weight.
4. The pharmaceutical composition of claim 1 , wherein the second filler is present in the pharmaceutical composition in an amount of from about 5% to about 15% by weight.
5. The pharmaceutical composition of claim 1 , wherein the second filler is present in the pharmaceutical composition in an amount of about 9% by weight.
6. The pharmaceutical composition of claim 1 , wherein the sodium carbonate is present in the pharmaceutical composition as sodium carbonate monohydrate.
7. The pharmaceutical composition of claim 1 , wherein the elagolix sodium is present in the pharmaceutical composition in an amount equivalent to about 150 mg of Compound A.
8. The pharmaceutical composition of claim 1 , wherein the elagolix sodium is present in the pharmaceutical composition in an amount equivalent to about 200 mg of Compound A.
9. The pharmaceutical composition of claim 1 , wherein the elagolix sodium is present in the pharmaceutical composition in an amount equivalent to about 300 mg of Compound A.
10. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition further comprises a binder, wherein the binder is present in the pharmaceutical composition in an amount of from about 2 to about 5% by weight.
11. The pharmaceutical composition of claim 10 , wherein the binder comprises polyvinylpyrrolidone.
12. The pharmaceutical composition of claim 1 , wherein the pharmaceutical composition further comprises a lubricant, wherein the lubricant is present in the pharmaceutical composition in an amount of from about 1 to about 5% by weight.
13. A pharmaceutical composition comprising:
from about 20 to about 60% by weight of sodium 4-((R)-2-[5-(2-fluoro-3-methoxy-phenyl)-3-(2-fluoro-6-trifluoromethyl-benzyl)-4-methyl-2,6-dioxo-3,6-dihydro-2H-pyrimidin-l-yl]-1-phenyl-ethylamino)butanoate (“elagolix sodium”);
from about 10 to about 30% by weight of sodium carbonate;
a first filler in an amount from about 20% to about 50% by weight and a second filler in an amount from about 1% to about 20% by weight,
wherein the first filler is mannitol and the second filler is pregelatinized starch;
a binder in an amount of from about 2 to about 5% by weight; and
a lubricant in an amount from about 1 to about 5% by weight;
wherein each weight percentage is on the basis of the total weight of the pharmaceutical composition, and
wherein said composition is in the form of a stable immediate release tablet.
14. The pharmaceutical composition of claim 13 , wherein the elagolix sodium is present in the pharmaceutical composition in an amount equivalent to about 150 mg of Compound A.
15. The pharmaceutical composition of claim 13 , wherein the elagolix sodium is present in the pharmaceutical composition in an amount equivalent to about 200 mg of Compound A.
