Abstract
The invention discloses a tranexamic acid freeze-dried powder injection and a preparation method thereof, comprising the following components in parts by weight: 0.05-10 parts of tranexamic acid, 1-100 parts of freeze-dried powder proppant, and a proper mount of pH regulator. The invention belongs to hemostasis curative, is a freeze-dried powder injection, has stable performance to light, heat, oxygen, water and the like, and has no pollution as well as convenient operation, transportation and storage. The tranexamic acid freeze-dried powder injection is suitable for various haemorrhages caused by acute, chronic, local, systemic and primary fibrinolysis, trauma or operation haemorrhages of organs rich in plasminogen activators, such as prostate and the like and is used as an antagonist of tectotype plasminogen activators (t-PA), streptokinase and urokinase. The tranexamic acid freeze-dried powder injection is also suitable for thrombolytic haemorrhage caused by abortion and amniotic fluid embolism, is used for preventing or lightening haemorrhage of a haemophile after exelcymosis or oral cavity operation, haemorrhage caused by light diseases of nervous centralis pathological changes, and is used for treating hereditary angioneuroticedema and active hemorrhage of haemophile.
Description
Technical field: [0001] The invention belongs to hemostatic medicine, in particular to a tranexamic acid freeze-dried powder injection, and also relates to a preparation method of the injection. Background technique: [0002] The present invention is mainly used for treating various hemorrhages caused by acute or chronic, localized or generalized hyperfibrinolysis, such as bleeding in oral cavity, surgical operation, trauma, obstetrics and gynecology, and gastrointestinal tract. At present, the preparation of this product is a water injection, and there are many inconveniences in the process of use: 1. The liquid needs to be pumped many times in the actual operation, and the preparation is easily contaminated by bacteria, resulting in unqualified heat source. 2. In actual clinical practice, many diseases require reducing the amount of fluid infusion, but water acupuncture cannot solve the problem. 3. In the cold season, especially in the north and alpine regions, there are ...
