Abstract

The invention belongs to the technical field of pharmaceutical preparation and relates to a pharmaceutical composition containing sodium ozagrel and a preparation method thereof. The pharmaceutical composition comprises, by weight, ozagrel: sodium hydroxide: mannitol: dextran: arabinose=(38-40):( 6-8):( 10-12): (10-12):(20-22). The pharmaceutical composition in the ozagrel prescription added with the appropriate amount of arabinose can greatly reduce the vascular irritation, and has a significant effect on relieving nausea, vomiting, diarrhea, loss of appetite, and fullness. The preparation method of the invention has the advantages of improving the stability of the drug after improving the process.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and relates to a pharmaceutical composition containing ozagrel sodium and a preparation method thereof. Background technique [0002] Ozagrel is a selective thrombosis A2 (TXA2) synthetase inhibitor, which has anti-platelet aggregation and blood vessel expansion effects, and can inhibit cerebral thrombosis and cerebral vasospasm. It can be used to improve the symptoms of vasospasm and cerebral ischemia after subarachnoid hemorrhage operation. It entered the market for the first time in Japan in 1988 as an antithrombotic drug. [0003] The deficiency of the existing ozagrel injection is that it has blood vessel irritation during injection, and even causes local pain. At the same time, because the existing ozagrel sodium is particularly stable in aqueous solution, in order to further improve the ozagrel sodium injection Stability, especially propose the present invention. Co...
