Abstract

The invention relates to a potassium sodium dehydroandroandrographolide succinate and a composition thereof. The composition contains andrographolide as pharmaceutically-active component, mannitol, calcium sodium EDTA, vitamin C and phosphate buffer. The composition for injection contains, per 1000, 20-200g of potassium sodium 14-dehydro-11,12- didehydroandrographolide-3,19-succinate, 3.868g of disodium hydrogen phosphate, 0.449g of sodium dihydrogen phosphate, 20-200g of mannitol, 0.5-5g of calcium sodium EDTA and 0.2-2g of vitamin C.

Description

Technical field: [0001] The invention relates to a pharmaceutical composition, in particular to a freeze-dried pharmaceutical composition of Yanhuning for injection. Background technique: [0002] Yanhuning, the chemical name is: 14-dehydro-11,12-didehydroandrographolide-3,19-disuccinic acid half ester sodium potassium salt, abbreviation: andrographolide succinic acid half ester sodium potassium salt, It is a medicine made from pure traditional Chinese medicine after extraction and synthesis, and has the characteristics of good solubility. It has pungent and cool solution, cool and detoxification, antiviral and antibacterial effects. [0003] The already-marketed Yanhuning injection is a freeze-dried powder injection, which is stabilized by adding sodium bicarbonate to adjust the pH value to achieve a potassium-sodium balance. However, low-temperature storage is still required to avoid discoloration of the drug during use. In the production process, adding activated carbon...
