SOLID FORMS OF LINEZOLID AND PROCESSES FOR PREPARATION THEREOF

摘要

Novel crystalline forms of Linezolid, designated as Form TIII, Form V, Form VI, Form IX, Form X, Form XII, Form XIV, Form XVII, and Form XVIII, are disclosed. The novel crystalline forms are characterized by powder X-ray diffraction, FTIR and FTRaman spectroscopy, and differential scanning calorimetry. Methods of preparing the novel crystalline forms, pharmaceutical compositions comprising the novel crystalline forms, and methods of using the novel crystalline forms to treat gram positive bacterial infections are also described. Amorphous Linezolid is also disclosed.
