Systematic Review of Tranexamic Acid Adverse Reactions

Abstract

Background Tranexamic acid is a synthetic lysine derivate that exerts its antifibrinolytic effect by reversible blocking lysine binding sites on plasminogen preventing fibrin degradation. It is widely used for haemorrhage or risk of haemorrhage in increased fibrinolysis or fibrinogenolysis. Aim The aim of our work was to review the literature regarding the best evidence on tranexamic adverse reactions and to describe them according to the apparatus involved. Methods The literature was searched for publications on tranexamic acid adverse reactions, adverse events, using MEDLINE, Scopus, Embase, Web of Science and Google Scholar. Results In the light of the results, seems to be clear that tranexamic acid causes several adverse reactions involving different apparatus. Hypersensitivity reactions, cerebrovascular infarction, myocardial infarction and pulmonary embolism seem to be the more common tranexamic acid adverse reactions. Conclusion Despite the wide use of tranexamic acid the number of cases reported for type of reaction is relatively low, thus causing a not easy understanding of mechanisms underlying the adverse reaction. Therefore, it would be appropriate to conduct epidemiological studies on a large scale in order to better understand risk factors favoring tranexamic acid adverse reactions and encourage pharmacovigilance in medical practice.

Trauma‐targeted delivery of tranexamic acid improves hemostasis and survival in rat liver hemorrhage model

“…In fact, free TXA‐treated rats showed signs of aggravating lung thrombosis. Interestingly, although several recent clinical trials have indicated safety and survival benefits of TXA in trauma, there also exist documented cases as well as retrospective study indications of thromboembolism risks associated with TXA use therefore, the optimal delivery strategies and dosing of TXA still remain to be further studied. To this end, our targeted nanoparticle‐based system can be a potential new and safe strategy.…”

Melasma Tipe Epidermal Diterapi Dengan Injeksi Asam Traneksamat Intradermal Serial Dan Tabir Surya

“…17 Beberapa efek samping TA 250 mg per hari antara lain fixed drug eruption, perdarahan, infark serebrovaskular, dan emboli paru. 18 Efektivitas TA topikal masih diperdebatkan dan diragukan, karena memiliki sifat larut air sehingga membatasi penyerapan transepidermal. 17 Pada kasus ini pemberian asam traneksamat secara injeksi intradermal setiap 2 minggu selama 1 bulan memberikan perbaikan klinis.…”

Leczenie farmakologiczne krwioplucia u pacjenta z rozpoznaniem guza płuca i utrwalonym migotaniem przedsionków

“…W literaturze opisano kilkunastu chorych, u których stwierdzono incydenty zakrzepowo-zatorowe obserwowane podczas leczenia kwasem traneksamowym [13]. Konieczne zatem było wykluczenie aktywnego krwawienia do pęcherza moczowego, ze względu na kilkukrotne operacje tego narządu u pacjenta.…”
