The invention provides a tranexamic acid injection and a preparation method of the same. In the preparation technology, the added active carbon for needles is preprocessed as follows: washing the active carbon for needles with acetone, alcohol and edetic acid water solution, and drying to remove residual metals and other impurities in the added active carbon for needles. The preprocessed active carbon for needles is used for preparing the tranexamic acid injection, thus, the generation of impurity-Z-isomer can be reduced, and the quality of the tranexamic acid injection is guaranteed. |
