Production method of pregabalin-containing composition and pregabalin-containing composition |
| abstract |
Provided are a production method of a pregabalin-containing composition, which suppresses crystallization of pregabalin, and a pregabalin-containing composition that shows suppressed crystallization of Pregabalin. The production method of the pregabalin-containing composition of the present invention contains steps of:n (1) dissolving pregabalin in an aqueous solution of an acid to prepare an aqueous solution of a salt of pregabalin; (2) mixing the aqueous solution of pregabalin salt and a hydrophilic resin to prepare a mixture thereof; and (3) concentrating the mixture; wherein the acid has an acid dissociation constant lower than that of pregabalin. |
