Abstract

The invention belongs to the field of pharmaceutical preparations and particularly discloses a tranexamic acid external semisolid preparation and a preparation method thereof. The semisolid preparation is one of gels, suppositories and ointments prepared from tranexamic acid serving as an active ingredient and other pharmaceutically acceptable auxiliary materials. The tranexamic acid external semisolid preparation disclosed by the invention has high physiological skin compatibility, and the haemostatic effect of the tranexamic acid is effectively improved.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a semi-solid preparation of tranexamic acid for external use and a preparation method thereof. Background technique [0002] Tranexamic acid is also known as tranexamic acid, tranexamic acid, the chemical name is trans-4-(aminomethyl)cyclohexanecarboxylic acid, molecular formula: C 8 h 15 NO 2 , molecular weight: 157.21. Trans-4-(aminomethyl)cyclohexanecarboxylic acid (abbreviated as trans-AMCA or AMCA), has significant anti-fibrinolytic activity, can stabilize fibrin, and is effective for coagulation factors, platelets, vascular factors and tissue factor disorders. It is an effective hemostatic agent and has been widely used clinically in China, and it is included in the new edition of the Chinese Pharmacopoeia. [0003] The external preparation can directly act on the target site, avoid the first-pass effect of the liver, increase the local concentration of the drug at the...
