An analysis comparing TXA at varying doses (high and low dose) found that a plasma concentration of 20 mcg/mL is sufficient for 80% fibrinolysis inhibition, while 100 mcg/mL offers 100% inhibition of fibrinolysis.11 The clinical difference may not be significant, but given that cardiac surgery with cardiopulmonary bypass creates a hyperfibrinolytic state, a higher plasma concentration may indeed offer improved efficacy.

However, given the dynamic fibrinolytic process, empiric administration in these clinical conditions should transition to guided-use by viscoelastic testing (unless laboratory markers of fibrinolysis such as D-dimers or fibrin degradation products are promptly available) on hospital arrival. 2019;30:110. 63.

Experts recommend that providers consider TXA as a therapeutic adjunct for treating PPH after vaginal or cesarean delivery and that future studies examine goal-directed treatment protocols using functional coagulation assays.24,81,82 Clinicians based in developing countries or hospitals with limited access to blood products and other resources may have a lower threshold for using TXA than those based in well-resourced and well-staffed hospitals.

With respect to seizure risk, TXA doses utilized in orthopedic surgery (1020 mg/kg) do not appear to be associated with an increased risk of seizure.107, Pharmacokinetic studies have established that the optimal serum TXA concentration in orthopedic surgery is >10 g/mL.98,108,109 Therapeutic levels can be achieved via oral, topical, or IV administration by different pharmacokinetic profiles.108,110,111 Current evidence demonstrates that there is no difference in the effect of TXA on reduced blood loss, transfusion, or incidence of thrombotic complications when assessing studies that utilized different routes of TXA administration for major joint arthroplasty.102,105,112115 Use of 10 to 20 mg/kg of TXA intravenously, in single or divided doses, remains one of the most common doses and methods of drug administration.13,14 One analysis suggested that combining IV and intraarticular use was superior to IV TXA alone at reducing blood loss and transfusion.100. WebMedscape - Indication-specific dosing for Cyklokapron (tranexamic acid injection), frequency-based adverse effects, comprehensive interactions, contraindications, WebCSTs should know the precautions to be taken when ICS is used as well as contraindications. No increased risk of venous thrombosis or myocardial infarction was observed in those patients who received TXA.106 However, in the absence of a large prospective randomized-controlled trial, the potential risk of thrombosis must be weighed against the benefit of minimizing blood loss in each patient at high thrombosis risk (eg, patients with recent coronary artery stents, recent stroke, or hypercoagulability). 1978;6:8388.

Sentilhes L, Madar H, Mattuizzi A, et al. With a growing emphasis on patient blood management, TXA has become an integral aspect of perioperative blood conservation strategies. A recent study examining TXA dosing in cardiac surgical patients with chronic kidney disease (CKD) reported prolonged elevation in therapeutic concentrations of TXA in CKD stages 3, 4, or 5 when compared to stages 1 or 2.53 To account for these elevated concentrations, which could be associated with a higher risk of adverse events, the authors created an optimized dosing regimen based on CKD stage and glomerular filtration rate (lower doses with worsening renal function). 2015;123:214221.

Classification of examinations and tests needed before POP initiation. TXA in cases of subarachnoid hemorrhage has been limited due to previous concerns for cerebral ischemia and infarction; however, investigations of efficacy and safety continue in this setting.
