CHITOSAN ADDUCT WITH TRANEXAMIC ACID AND ITS HAEMOSTATIC EFFECT
Chitosan is a cationic polymer capable of binding acidic drugs. In addition, it has haemostatic and antimicrobial activity. Chitosan derivatives withanti-fibrinolytic properties may present increased effectiveness, especially when the added substance forms an adduct with chitosan. The aim of this work was to study the haemostatic action of the chitosan–tranexamic acid complex. Two chitosan solutions (molecularweight of 250 and 625 kDa at pH 5.7 and 6.2, and after tranexamic acid had been added to chitosan solutions) werestudied. Haemostatic evaluation was performed on white outbred mice. The time to complete cessation of bleeding from the tail was determined. Chitosan 625 kDa at pH 6.2 had the best haemostatic properties. Adding tranexamic acid to the chitosan solution reduced the bleeding time. This phenomenon was more pronounced for chitosan 625 kDa. Compared with control animals, this chitosan reduced bleeding arrest time by 30% and the chitosan–tranexamic acid adduct reduced the bleeding arrest time by 75%.
期刊介绍：
Progress in the Chemistry and Application of Chitin and its Derivatives is an annual journal focused on all aspects of production, modification, enzymology and application of chitin and its many derivatives, including chitosan. The journal publishes full-length papers as well as invited reviews. To be considered, papers must present original research that has not been published or accepted for publication elsewhere. The language of the journal will be English.
