Embodiment 1

[0034] Example 1 Preparation of 100mg / ml Fulvestrant Injection

[0035]

[0036]

[0037] Preparation: Get the prescribed amount of fulvestrant, ethanol (95%), benzyl alcohol, and medium-chain triglycerides, stir and mix at room temperature until fulvestrant is completely dissolved, add castor oil to the final volume (10ml), stir and mix uniform. Filter the mixed solution through a 0.2 micron filter 1-2 times to achieve the purpose of sterilization. Under sterile conditions, dispense the sample into injection vials or pre-filled injection devices, and obtain it after visual inspection.

Abstract

The invention relates to a pharmaceutical composition of fulvestrant. The pharmaceutical composition comprises: (1) fulvestrant; (2) at least one pharmaceutically acceptable alcohol; (3) medium-chain triglyceride; and (4) a castor oil matrix.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and relates to a fulvestrant preparation suitable for injection administration, as well as a preparation method and application of the preparation. Background technique [0002] According to the global tumor statistics report published in 2011, there were about 12.7 million cancer cases and 7.6 million cancer deaths in 2008, of which 56% were cases and 64% were deaths in developing countries. Breast cancer is the cancer with the highest morbidity and mortality among women, accounting for about 23% of the total cancer cases and 14% of the cancer deaths. In developing countries, breast cancer ranks first among female cancer deaths, surpassing cervical cancer, and breast cancer seriously endangers human health. [0003] There are estrogen receptors (ER) in many breast cancer cells. After estrogen binds to these receptors, it will promote cell proliferation and stimulate tumor growth throu...
