Abstract

The invention relates to a pharmaceutical composition of aminomethylbenzoic acid freeze-dried powder for injection. Specifically, in one aspect, the present invention relates to a pharmaceutical composition of lyophilized powder injection, which comprises aminotoluic acid, lyophilized excipients such as mannitol, and an optional acid-base regulator. The freeze-drying excipient is selected from sucrose, glucose, mannitol, lactose, sorbitol, and glycine, and the weight ratio of aminomethylbenzoic acid to the freeze-drying excipient is 100:50-500. On the other hand, the present invention also relates to a method for preparing the aminotoluic acid freeze-dried powder injection pharmaceutical composition, which is carried out by using a conventional freeze-dried powder injection preparation method. Aminomethylbenzoic acid freeze-dried powder for injection of the present invention can be used for hemorrhage caused by excessive primary fibrinolysis, including acute and chronic, localized or systemic hyperfibrinolytic hemorrhage, the latter is common in cancer, leukemia , obstetrics and gynecology accidents, severe liver disease bleeding, etc., and has good properties that are expected.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a hemorrhage that can be used for hemorrhage caused by excessive primary fibrinolysis, including acute and chronic, localized or systemic hyperfibrinolytic hemorrhage, which is common in cancer, leukemia, The pharmaceutical composition of freeze-dried powder injection for obstetrics and gynecology accidents, severe liver disease bleeding, etc., especially relates to a pharmaceutical composition of freeze-dried powder injection containing aminomethylbenzoic acid. The freeze-dried powder injection pharmaceutical composition of the present invention has expected good properties. Background technique [0002] Aminomethylbenzoic acid (Aminomethylbenzoic Acid), p-aminomethylbenzoic acid monohydrate, also known as anti-blood fibrinolytic aromatic acid, p-carboxybenzylamine, 4-(aminomethyl)benzoic acid, 4-aminomethylbenzoic acid , p-aminomethylbenzoic acid; 4-(Aminometmyl)benzoic acid, 4...
