Problems solved by technology

[0009] The object of the present invention is to provide a pharmaceutical composition of bortezomib, which can quickly dissolve bortezomib, thereby rapidly reacting with polyalcohol excipients such as mannitol to form a more stable borate ester, However, when the pharmaceutical composition is prepared into a freeze-dried powder injection, there is no need to add additional antioxidants, which can well solve the stability problem of the bortezomib freeze-dried powder injection itself and the problem of poor resolubility.

Abstract

The invention belongs to the technical field of medicines and particularly relates to a drug composition of bortezomib and a preparation method thereof. The drug composition disclosed by the invention contains bortezomib, tert butyl alcohol, sodium chloride and an excipient in the mass ratio of 1:0.5:(1-5):(5-20). The drug composition adopts freeze-dried powder injection or water injection, preferably the freeze-dried powder injection. The drug composition contains tert butyl alcohol and sodium chloride besides the conventional excipient; through adding tert butyl alcohol, bortezomib can be rapidly dissolved and rapidly reacted with polyalcohol excipients such as mannitol to form more stable borate, so that the stability problem of the bortezomib freeze-dried powder injection per se is solved; and through adding the drug active constituent i.e. sodium chloride, the normal physiological and biochemical activities and functions in vivo are fully guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a pharmaceutical composition of bortezomib and a preparation method thereof. Background technique [0002] Bortezomib (PS-341), trade name Velcade, is a new type of anti-tumor drug developed by Millennium Pharmaceutical Company of the United States. The drug leads to the death of tumor cells by blocking the degradation of various proteins that regulate apoptosis and signal transduction in cells. A large number of studies have found that bortezomib has strong anti-tumor activity against a variety of tumors, especially multiple myeloma, mantle cell lymphoma, other B-cell lymphomas, and Hodgkin's lymphoma in hematological tumors. [0003] Yi Wenyuan and others pointed out in "Research Progress of Proteasome Inhibitors Reversing Multidrug Resistance of Tumors" ("Foreign Medicine and Pharmacy Volume", April 2007, Volume 34, Issue 2) that boronic acid peptides include bor...
