Stable micelles of fatty acid esters

摘要

Compositions including at least one Omega-3 fatty acid ester and at least one surface active agent are provided; wherein the compositions form micelles when in contact with an aqueous medium. Also provided is a method of administering to a subject such a composition, wherein the at least one Omega-3 fatty acid ester forms micelles when in contact with an aqueous medium, and the bioavailability of the at least one Omega-3 fatty acid ester is substantially independent of a food effect. The compositions are useful for treating cardiovascular conditions or disorders in a subject and for reducing side effects associated with the ingestion of Omega-3 fatty acid esters. Further provided are also various dosage forms for administering the compositions and use of the compositions in functional foods. Provided herein are also kits with instructions on how to administer the compositions.

1. A pharmaceutical composition which self-micellizes upon contact with an aqueous medium to form spherical micelles which have an average diameter of from about 1 μm to about 10 μm, or stable micelles pre-formed from said composition, and which provide for absorption of omega-3 fatty acid esters substantially free of any food effect, said pharmaceutical composition comprising:
a. from about 60% (wt/wt)-about 85% (wt/wt) of at least one omega-3 fatty acid ester, selected from the group consisting of (all-Z omega-3)-5,8,11,14,17-eicosapentaenoic acids (EPA) ester, (all-Z omega-3)-4,7,10,13,16,19-docosahexaenoic acids (DHA) ester, hexadecatrienoic acid (“HTA” or 16:3 (n-3), or all-Z-7,10,13-hexadecatrienoic acid), α-linolenic acid (“ALA” or 18:3 (n-3), or all-Z-9,12,15-octadecatrienoic acid), stearidonic acid (“SDA” or 18:4 (n-3) or all-Z-6,9,12,15-octadecatetraenoic acid), eicosatrienoic acid (“ETE” or 20:3 (n-3) or all-Z-11, 14, 17 eicosatrienoic acid), eicosatetraenoic acid (“ETA” or 20:4 (n-3), heneicosapentaenoic acid (“HPA” or 21:5 (n-3) or all-Z-6,9,12,15,18-heneicosapentaenoic acid), docosapentenoic acid (“DPA”, or clupanodonic acid or 22:5 (n-3) or all-Z-7, 10, 13, 16, 19-docosapentenoic acid), tetracosapentenoic acid (24:5 (n-3) or all-Z-9,12,15,18,21-tetracosapentenoic acid), and tetracosahexaenoic acid (nisinic acid or 24:6 (n-3) and all-Z-6,9,12,15,18,21-tetracosahexaenoic acid; and b. a surface active agent which comprises, in combination, at least one non-ionic polyoxyethylene glycol sorbitan alkyl ester (a polysorbate) selected from the group consisting of polyoxyethylene (20) sorbitan monolaurate (polysorbate 20), polyoxyethylene (20) sorbitan monopalmitate (polysorbate 40), (polyoxyethylene (20) sorbitan monostearate (polysorbate 60) and polyoxyethylene (20) sorbitan monooleate (polysorbate 80); and a block copolymer of polyethylene glycol and polypropylene glycol having the formula [(HO(C2H4O)64 (C3H6O)37 (C2H4O)64 H] (Poloxamer 237);
wherein said at least one polysorbate is present in an amount within the range of about 15% (wt/wt) to about 31% (wt/wt) of said composition; and said Poloxamer 237 is present in an amount within the range of about 0.5% (wt/wt) to about 5% (wt/wt) of said composition; whereby said combination of surface active agents are effective to form said stable micelles upon contact with said aqueous medium; wherein said composition is free of active ingredients other than omega-3 fatty acid esters; and wherein said composition when administered to a human at equal dosage strengths provides for substantially the same bioavailability when administered with or without food to said human in need of such administration; and whereby said pharmaceutical composition self-micellizes in an aqueous medium, thus forming spherical micelles having an average diameter of from about 1 μm to about 10 μm, which provide for absorption of said omega-3 fatty acid esters substantially free of any food effect.
