Zusammenfassung:Novel crystal forms of the fluoroquinolone, [S-(R*,S*)]-1-cyclopropyl-6-fluoro-1,4-dihydro-8-methoxy-7-[3-[1-(methylamino)ethyl]-1-pyrrolidinyl]-4-oxo-3-quinolinecarboxylic acid are disclosed. The forms are characterized by one methanol solvate form, and three anhydrous polymorphic forms, of which, Form III exhibits greatest stability and decreased hygroscopicity.
