Abstract

The invention relates to a pharmaceutical composition of dexamethasone sodium phosphate for injection and a preparation method of the pharmaceutical composition, and in particular relates to a freeze-dried powder injection pharmaceutical composition of dexamethasone sodium phosphate. The freeze-dried powder injection pharmaceutical composition comprises dexamethasone sodium phosphate and a freeze-dried excipient which is selected from one or more of mannitol, glycine, lactose and saccharose, wherein the weight ratio of dexamethasone sodium phosphate to mannitol is 1:(1-50). The freeze-dried powder injection pharmaceutical composition of dexamethasone sodium phosphate disclosed by the invention is applicable to treatment of irritability and autoimmunity-related diseases, is particularly used for connective tissue diseases, active rheumatism, rheumatoid arthritis, lupus erythematosus, severe bronchial asthma, severe dermatitis, ulcerative colitis, acute leukemia and the like, and also can be used for comprehensive treatment on serious infection and poisoning, and malignant lymphoma. The freeze-dried powder injection pharmaceutical composition of dexamethasone sodium phosphate disclosed by the invention has excellent pharmaceutical property as described in the specification.
