Abstract

The invention relates to a composition of angiostatin or its medicinal salt, and a preparation method and a use thereof. The composition comprises 25-45wt% of angiostatin (a compound of formula I) or its pharmaceutically acceptable salt, and a medicinal excipient which can be used for treating over-proliferation diseases, such as cancers.

Description

technical field [0001] The invention relates to a composition containing erlotinib or a pharmaceutically acceptable salt thereof, a preparation method thereof and an application thereof in preparation of a medicine for treating hyperproliferative diseases. Background technique [0002] Erlotinib (also known as N-(3-ethynylphenyl)-6,7-bis(2-methoxyethoxy)-4-quinazolinamine), whether it is hydrochloride or methanesulfonic acid salt, are used in the treatment of hyperproliferative diseases such as cancer in mammals. [0003] Lung cancer is the most common malignant tumor in the world, and it is also the malignant tumor with the highest morbidity and mortality among urban residents in my country. With the influence of smoking and various environmental factors, the morbidity and mortality also show a continuous upward trend. In lung cancer, non-small cell lung cancer (Non-Small Cell Lung Cancer, NSCLC) accounts for about 80-85% of the total number of lung cancers. [0004] Non-...
