Abstract
Polymorphs Form B, Form C, and amorphous of 6-[4-(1-cyclohexyl-1H-tetrazol-5-yl)butoxy]-3,4-dihydro-2(1H)-quinolinone, commonly known as cilostazol, have been identified. These polymorphs may be formed in pure form, in combination with each other, in combination with other polymorphs of cilostazol, or together with other pharmaceutical agents. Processes for preparing these polymorphs, and combinations of these polymorphs, as well as methods of use and unit dosages of these polymorphic forms, and their combinations, are described.
