Abstract

The present invention relates to Chinese medicine preparation, and is especially freeze dried injection powder preparation for treating coronary heart disease and its preparation process. The freeze dried injection powder preparation is prepared with red sage and Chuanxiong rhizome as main material, and through the steps of water extraction, precipitating to eliminate impurity, refining with macroporous resin, filtering, compounding the refined extract and freeze drying excipient with injection water to form solution, refining, packing and low temperature freeze drying. Each injection contains protocatechuic aldehyde 10-15mg, total phenolic acid 300-350mg and ligustrazine 10-15mg. The present invention has the advantages of simple preparation process, low cost, high stability, obvious curative effect, etc.

Description

technical field [0001] The invention belongs to traditional Chinese medicine preparations, in particular to a freeze-dried powder injection preparation for treating coronary heart disease and a preparation method thereof. Background technique [0002] Guanxinning Injection is a compound composed of Danshen and Chuanxiong. It has the effects of promoting blood circulation and removing blood stasis, dredging the meridians and nourishing the heart. It is used for angina pectoris of coronary heart disease. Modern pharmacological studies have confirmed that it has the functions of dilating coronary arteries, increasing coronary blood flow, improving myocardial ischemia, inhibiting blood coagulation, promoting fibrinolysis, and improving blood rheology. In recent years, it has been used more clinically. [0003] Guanxinning injection currently used clinically has a low drug concentration, but the clinical dosage is large (50-100ml), and the stability of Guanxinning injection is p...
