A composition comprising D-glucitol, 1-deoxy-1-(methylamino)-, 1-(6-amino-3,5-difluoropyridin-2-yl)-8-chloro-6-fluoro-1,4-dihydro-7-(3-hydroxyazetidin-1-yl)-4-oxo-3-quinolinecarboxylate salt prepared by a process comprising the steps of:
- (1) combining 1-(6-amino-3,5-difluoropyridin-2-yl)-8-chloro-6-fluoro-1,4-dihydro-7-(3-hydroxyazetidin-1-yl)-4-oxo-3-quinolinecarboxylate and 1-deoxy-1-(methylamino)-D-glucitol in a solvent to provide a mixture;
- (2) filtering said mixture to provide a solid;
- and
- (3) drying said solid to provide said D-glucitol, 1-deoxy-1-(methylamino)-, 1-(6-amino-3,5-difluoropyridin-2-yl)-8-chloro-6-fluoro-1,4-dihydro-7-(3-hydroxyazetidin-1-yl)-4-oxo-3-quinolinecarboxylate salt.
A therapeutic composition comprising at least one excipient and D-glucitol, 1-deoxy-1-(methylamino)-, 1-(6-amino-3,5-difluoropyridin-2-yl)-8-chloro-6-fluoro-1,4-dihydro-7-(3-hydroxyazetidin-1-yl)-4-oxo-3-quinolinecarboxylate salt prepared by a process comprising the steps of:
- (1) combining 1-(6-amino-3,5-difluoropyridin-2-yl)-8-chloro-6-fluoro-1,4-dihydro-7-(3-hydroxyazetidin-1-yl)-4-oxo-3-quinolinecarboxylate and 1-deoxy-1-(methylamino)-D-glucitol in a solvent to provide a mixture;
- (2) filtering said mixture to provide a solid;
- and
- (3) drying said solid to provide said D-glucitol, 1-deoxy-1-(methylamino)-, 1-(6-amino-3,5-difluoropyridin-2-yl)-8-chloro-6-fluoro-1,4-dihydro-7-(3-hydroxyazetidin-1-yl)-4-oxo-3-quinolinecarboxylate salt.
