Abstract

The present invention relates to a method for solubilizing poorly water-soluble dietary supplements and pharmaceutically active agents, to the solubilisate produced by this method and respective uses as a dietary supplement or pharmaceutical dosage form. A phosphatidylcholine-based solubilization method is disclosed.

Claims (19)

1. A method for solubilizing a poorly water-soluble pharmaceutically active agent or dietary supplement, comprising the following steps:

a) Providing one or more poorly water-soluble pharmaceutically active agents or dietary supplements in the-range of 0.5 to 25 weight percent at room temperature and a pressure of 0.2 bar to 1 bar,

wherein “poorly water-soluble” designates a pharmaceutically active agent or dietary supplement that requires more than 250 ml of aqueous media over the pH range of 1-7.5 for their highest dose to be dissolved;

b) Adding in any sequence all the following solubilization agents to form a mixture:

one or more phosphatidylcholines in the range of 20 to 80 weight percent,

one or more medium-chain triglycerides in the range of 10 to 70 weight percent,

one or more lysophosphatidylcholines in the range of 1 to 15 weight percent,

one or more C 2 to C 4 alcohols in the range of 1 to 20 weight percent, and

one or more saturated or unsaturated C 14 to C 20 fatty acids in the range of 0.5 to 10 weight percent,

wherein the relative weight percentages of all ingredients add up to 100% and all solubilization agents are independently from one another a food additive, a pharmaceutically acceptable excipient, or both;

c) Heating the resulting mixture by continuously increasing the temperature with a continuous temperature increment of 0.5° C./min to 3° C./min over a period of 20 to 60 minutes;

d) Stopping the temperature increase in a temperature range of 30° C. to 125° C. as soon as a clear solution is reached to form a solubilisate; and

e) Allowing a resulting solubilisate to cool down to room temperature.

2. The method according to claim 1 , wherein said one or more saturated or unsaturated C 14 to C 20 fatty acids are oleic acid.

3. The method according to claim 1 , wherein said one or more C 2 to C 4 alcohols are ethanol.

4. The method according to claim 1 , wherein additionally in step b) one or more antioxidants in the overall range of 0.01 to 10 weight percent are added, said one or more antioxidants being a food additive, a pharmaceutically acceptable excipient, or both.

5. The method according to claim 4 , wherein said one or more antioxidants are is ascorbyl palmitate, at least one tocopherol, or both.

6. The method according to claim 1 , wherein the resulting solubilisate is used to mask a bitter or unpleasant taste and/or odor of the pharmaceutically active agent or dietary supplement.

7. The method according to claim 1 , wherein said one or more saturated or unsaturated C 14 to C 20 fatty acids is glyceryl stearate.
