Abstract

The invention provides a bortezomib pharmaceutic composition, and aims to solve the technical problem that the stability and dissolubility of the bortezomib are poor. The pharmaceutic composition contains bortezomib and amino acid in the mass ratio of 1:(2-100). By using the bortezomib pharmaceutic composition for injection, the dissolubility of the bortezomib can be effectively improved, and the effect is equivalent or superior to that of the products in the market. The bortezomib pharmaceutic composition is safe and non-irritant, the preparation cost is low, the preparation method is simple, and the stability is superior to that of the existing bortezomib preparation. The bortezomib pharmaceutic composition is favorable for industrial production.

Description

technical field [0001] The invention belongs to the field of medicine, in particular to the field of pharmaceutical preparations. The invention relates to a bortezomib pharmaceutical composition for injection. Background technique [0002] Bortezomib is a dipeptidyl boronic acid compound, which was approved by the FDA for marketing on May 19, 2003. Its trade name is "Velcade" and it is a freeze-dried powder for injection. For the treatment of relapsed and refractory multiple myeloma. The solubility of the bortezomib raw material in water is only 0.076mg / ml, the solubility of the raw material drug is low, and the direct preparation cannot reach a suitable concentration. Appropriate solubilization techniques need to be employed. [0003] [0004] The listed product "Wanke" adopts the technology of patents WO02059130 and WO2002059131. This patent employs complexes of bortezomib and sugars, including condensed sugars such as mannitol and sorbitol. This patent mixes bortez...
