Abstract

The invention provides a ozagrel sodium freeze-dried powder for injection with double auxiliary materials, relates to the field of pharmaceutical preparations and preparation methods, and mainly solves the problem of existing production of excipients in the production formula of ozagrel sodium freeze-dried powder for injection in the prior art The disadvantages of long freeze-drying time, high drying temperature and high energy consumption. The ozagrel sodium freeze-dried powder for injection uses double excipients, the excipients include mannitol and hydroxyethyl starch 130/0.4, the main drug is ozagrel sodium, and the weight ratio of the main drug to the excipients is 100:100‑100:140 , the weight ratio between mannitol and hydroxyethyl starch 130/0.4 is 100:30‑100:50. The ozagrel sodium freeze-dried powder for injection is prepared by using the above-mentioned main drug and auxiliary materials. The ozagrel sodium freeze-dried powder for injection provided by the invention is stable in quality, safe and effective, simple in production process, short in freeze-drying time during production, low in drying temperature and low in energy consumption.

Description

Technical field: [0001] The invention relates to the field of pharmaceutical preparations and preparation methods, in particular to a ozagrel sodium freeze-dried powder for injection with double auxiliary materials and a preparation method thereof. Background technique: [0002] Ozagrel sodium freeze-dried powder for injection is a thromboxane (TX) synthase inhibitor, which can prevent prostate H2 (PGH2) from generating thromboxane A2 (TXA2), and promote platelet-derived PGH2 to turn to endothelial cells. Endothelial cells are used to synthesize PGI2, thereby improving the abnormal balance of TXA2 and prostaglandin PGI2. Play the role of inhibiting platelet aggregation and dilating blood vessels. [0003] This product can improve the movement disorder in the acute stage of cerebral thrombosis, improve the circulation disorder in the acute stage of cerebral ischemia and improve the abnormal energy metabolism in cerebral ischemia. Intravenous administration can reduce plasma...
