Improved synthesis of lysine acetylsalicylate · glycine particles |
| abstract |
The invention relates to a method for the production of acetylsalicylic acid lysinate, optionally lysine acetylsalicylate · glycine, comprising the following steps: a) providing a solution of acetylsalicylic acid in ethanol; b) providing an aqueous solution of lysine; c) combining the solutions of step a) and b) to form a mixture; d) optionally stirring the mixture; e) adding acetone to the mixture; f) incubating the mixture, to allow the formation of a acetylsalicylic acid lysinate product; g) isolating the acetylsalicylic acid lysinate product; wherein acetylsalicylic acid is used in excess compared to lysine and wherein no seed crystals are added to the mixture; and optionally the following further steps: h) providing a recrystallized glycine; wherein the glycine has been recrystallized with the following steps: h1) dissolving glycine in water; h2) adding acetone to the glycine solution; h3) stirring the mixture until a precipitate is obtained; i) combining the recrystallized glycine of step h) with the acetylsalicylic acid lysinate product of step g) to obtain lysine acetylsalicylate · glycine (LASAG) particles. |
