Abstract:
The invention relates to a process for the preparation of a cyclodextrin/alpha-lipoic acid complex, wherein in a first step, an alpha-lipoic acid and a cyclodextrin are dissolved in an aqueous alkaline solution having a pH above pH 7, and in a second step an acid is added to lower the pH of the solution to a pH below pH 7.
