Description

technical field [0001] The invention relates to the technical field of medicine, and specifically provides an antibacterial drug cefoxitin sodium compound entity and its composition, preparation method and application. Background technique [0002] Polymorphic forms of chemical drugs play an important role in drug research. In the field of pharmacology, the research work on drug crystal forms and drug hydrates or drug solvates has been listed in the research scope of the National Twelfth Five-Year Major New Drug Innovation Science and Technology Major Project. Solvents of compounds, including hydrates, have been prepared and used in medicines for a long time. For example, the antineoplastic drug cyclophosphamide recorded in the 36th edition of the US Pharmacopoeia, the 6.1th edition of the European Pharmacopoeia, and the 2010 edition of the Chinese Pharmacopoeia was prepared in a solid form at room temperature. It exists in the form of hydrate, and the compound entity begin...
