Pharmaceutical compositions and related methods of delivery
View Patent ↗The pharmaceutical compositions described herein include a suspension which comprises an admixture in solid form of a therapeutically effective amount of a therapeutic agent and at least one salt of a medium chain fatty acid and a hydrophobic medium, e.g. castor oil or glyceryl tricaprylate or a mixture thereof. The pharmaceutical compositions described herein contain medium chain fatty acid salts and are substantially free of alcohols. The pharmaceutical compositions may be encapsulated in a capsule. Methods of treating or preventing diseases by administering such compositions to affected subjects are also disclosed.

4. The capsule of claim 1 , wherein the medium chain fatty acid salt has a chain length from about 6 to about 14 carbon atoms.
5. The capsule of claim 4 , wherein the medium chain fatty acid salt is sodium hexanoate, sodium heptanoate, sodium octanoate, sodium nonanoate, sodium decanoate, sodium undecanoate, sodium dodecanoate, sodium tridecanoate or sodium tetradecanoate, or a corresponding potassium or lithium or ammonium salt or a combination thereof.
6. The capsule of claim 5 , wherein the medium chain fatty acid salt is sodium octanoate.
7. The capsule of claim 1 , wherein the medium chain fatty acid salt is present in the capsule at an amount of 12% to 18% by weight.
8. The capsule of claim 1 , wherein the hydrophobic oily medium comprises a mineral oil, a paraffin, a fatty acid a monoglyceride, a diglyceride, a triglyceride, an ether or an ester, or a combination thereof.
9. The capsule of claim 1 , wherein the medium chain fatty acid salt is a lithium, potassium or ammonium salt.
10. The capsule of claim 1 , wherein the hydrophobic oily medium comprises glyceryl tricaprylate.
11. The capsule of claim 1 , wherein the composition further comprises a surfactant.
12. The capsule of claim 1 , wherein the composition comprises a therapeutically effective amount of octreotide and about 12-21% of sodium octanoate, about 5-10% of polyvinylpyrrolidone with a molecular weight of about 3000, about 20-80% of glyceryl tricaprylate, about 0-50% castor oil, about 3-10% surfactant and about 1% water.
13. The capsule of claim 1 , wherein the composition comprises a therapeutically effective amount of octreotide and about 12-21% of sodium octanoate, about 5-10% of polyvinylpyrrolidone with a molecular weight of about 3000, about 20-80% of glyceryl tricaprylate, about 3-10% surfactant and about 1% water.
14. The capsule of claim 13 , wherein the octreotide is present at an amount of less than 33%.
15. The capsule of claim 14 , wherein the composition comprises about 15% of sodium octanoate, about 10% of polyvinylpyrrolidone with a molecular weight of about 3000, about 30-70% glyceryl tricaprylate and about 6% of surfactant.
16. The capsule of claim 15 , wherein the surfactant is glyceryl monocaprylate and polyoxyethylene sorbitan monooleate.
17. The capsule of claim 1 , wherein the solid form comprises a particle or a plurality of particles.
18. The capsule of claim 1 , wherein the solid form further comprises a stabilizer.
19. The capsule of claim 16 , wherein the solid form further comprises a stabilizer.
20. The capsule of claim 1 , which is additionally enteric coated.
21. The capsule of claim 19 , which is additionally enteric coated.
22. The capsule of claim 8 , wherein the fatty acid is octanoic acid.
23. The capsule of claim 13 , wherein the octreotide is present at an amount of less than 25%.
