Abstract

The invention specifically relates to a novel potassium sodium dehydroandrographolide succinate compound and a pharmaceutical composition thereof, belonging to the technical field of medicines. The novel potassium sodium dehydroandrographolide succinate compound is a crystal. In an X-ray powder diffraction pattern obtained after measurement of the crystal with Cu-Kalpha rays, characteristic peaks appear when 2theta is equal to 7.3 DEG, 9.6 DEG, 12.0 DEG, 13.4 DEG, 15.9 DEG, 17.5 DEG, 18.0 DEG, 19.8 DEG, 23.4 DEG, 23.8 DEG, 24.6 DEG and 27.1 DEG. The pharmaceutical composition comprises the novel potassium sodium dehydroandrographolide succinate compound, glutamine, potassium sorbate and injection water. The dosage form of the pharmaceutical composition is a freeze-dried powder injection. The freeze-dried powder injection of potassium sodium dehydroandrographolide succinate has better stability and superior drug effect.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a new yanhuning compound and its pharmaceutical composition. Background technique [0002] Yanyuning, the chemical name is: 14-dehydroxyl-11,12-didehydroandrographolide-3,19-disuccinic acid half ester potassium sodium salt-hydrate, and the molecular formula is: C 28 h 34 KNaO 10 ·H 2 O. Yanhuning is a diterpene compound andrographolide extracted from the traditional Chinese medicine Andrographis paniculata, which is dehydrated andrographolide half-ester potassium succinate sodium salt, which is obtained by esterification, dehydration, and salt formation. Function and sedative effect, it is one of the commonly used drugs in TCM emergency. [0003] Yanhuning can inhibit early capillary permeability increase and inflammatory exudation edema, can specifically stimulate the pituitary-adrenal cortex function, promote the release of ACTH, and increase the biosynthesis...
