Abstract

The invention relates to an ozagrel sodium injection and a preparation method thereof, in particular to an ozagrel sodium injection for treating acute thrombotic cerebral infarction and movement disorders concomitant with cerebral infarction, preferably injection solution and lyophilized powder injection. The ozagrel sodium injection mainly comprises ozagrel serving as an active component and sodium hydroxide and citric acid serving as auxiliary materials. Solvent in the injection solution is water for injection. Excipient in the lyophilized powder injection is mannitol and/or sorbitol which can be combined in any one or two optional medicinal proportions, or no excipient is added.

Description

technical field [0001] The invention relates to an ozagrel sodium injection and a preparation method thereof, in particular to an injection used for treating acute thrombotic cerebral infarction and the motor disorder accompanied by cerebral infarction, and belongs to the technical field of pharmaceutical preparations. Background technique [0002] Ozagrel sodium, English name: Sodium Ozagrel, chemical name: trans-3-[4-(1H-imidazolyl-1-methyl)phenyl]-2-sodium acrylate, its chemical formula: [0003] [0004] Sodium ozagrel is the first thromboxane synthetase inhibitor listed in China, mainly used for the treatment of acute thrombotic cerebral infarction and the accompanying motility disorder of cerebral infarction, and for the improvement of cerebral vasospasm after subarachnoid hemorrhage surgery Contraction and concurrent cerebral ischemic symptoms. It can not only dissolve the thrombosis protein, but also prevent the formation of thrombus. [0005] Although ozagrel s...
