Abstract

The invention relates to a fludarabine phosphate composition for injection, which contains fludarabine phosphate and mannitol. A preparation method for the fludarabine phosphate composition comprises the following steps of: 1) preparation: putting the fludarabine phosphate and the mannitol in a preparation tank in a weight ratio of 1:1, adding water for injection into the tank, stirring the mixture, adjusting the pH to 7.7 by using 0.1mol/L phosphoric acid solution and 0.1mol/L sodium hydroxide solution to fully dissolve the mixture, and continuously stirring the solution for uniform mixing; 2) sterile filtration, packing and half plugging; and 3) vacuum freezing drying. The fludarabine phosphate composition has the advantages of simple formula, advanced process, good appearance formation, uniform and stable quality, uniform and accurate content, thorough moisture drying and better stability.

Description

technical field [0001] The present invention relates to a fludarabine phosphate composition for injection and a preparation method thereof, and the fludarabine phosphate composition prepared by the method can be used for B-cell chronic lymphocytic leukemia (CLL) patients treat. Background technique [0002] The chemical name of fludarabine phosphate is chemical name: 9-β-D-arabinofuranyl-2-fluoroadenine-5'-phosphate. [0003] Chemical Structure: [0004] [0005] Molecular formula: C 10 h 13 FN 5 o 7 P [0006] Molecular weight: 365.21. [0007] Chronic lymphocytic leukemia (CLL) is the most common leukemia in adults. 95% of CLL patients originate from B cells (B-CLL), and only a very small number belong to malignant transformation of T cells. B-CLL is classified as non-Hodgkin Lymphoma. In the past, chronic lymphocytic leukemia (CLL) was regarded as an incurable disease, and palliative and symptomatic treatment was adopted clinically. The nucleotide congener fl...
