Abstract
The invention relates to 1-[2-(4-benzyl-4-hydroxy-piperidin-1-yl)-ethyl]-3-(2-methyl-quinolin-4-yl)-urea as a crystalline, stoichiometrically defined and non-hygroscopic sulfate salt and a process for its preparation. Further, the present invention relates to the use of said 1-[2-(4-benzyl-4-hydroxy-piperidin-1-yl)-ethyl]-3-(2-methyl-quinolin-4-yl)-urea as a crystalline, stoichiometrically defined and non-hygroscopic sulfate salt alone or in combination with other compounds. Further, the present invention relates to formulations of said 1-[2-(4-benzyl-4-hydroxy-piperidin-1-yl)-ethyl]-3-(2-methyl-quinolin-4-yl)-urea as a crystalline, stoichiometrically defined and non-hygroscopic sulfate salt in the preparation of pharmaceutical compositions. The invention also relates to the use of such sulfate salts in formulations as neurohormonal antagonists.
