Tranexamic Acid for Upper GI Bleeding

Efficacy of TXA in Upper GI Bleeding

Meta-analyses have shown that tranexamic acid therapy appears to reduce the need for surgical intervention and tends to reduce mortality in ulcer bleeding patients, according to the American Gastroenterological Association 1, 2
Current guidelines do not recommend TXA as routine therapy for upper GI bleeding, stating that further studies are necessary before it can be recommended, as suggested by the American Gastroenterological Association 1, 2

Endoscopic therapy remains the first-line treatment for actively bleeding ulcers with high-risk stigmata, as recommended by the American College of Physicians 3
Following successful endoscopic therapy, high-dose proton pump inhibitor therapy is recommended, according to the American Gastroenterological Association 1, 2
H2-receptor antagonists are not recommended in the management of patients with acute upper GI bleeding, as stated by the American College of Physicians 4
Somatostatin and octreotide are not recommended in the routine management of patients with acute nonvariceal upper GI bleeding, as suggested by the American College of Physicians 3, 4

For patients with advanced malignancy and bleeding, TXA may be considered as part of a pragmatic approach, although this carries an increased risk of thrombosis, as noted by the European Society for Medical Oncology 5

While TXA shows promise in reducing surgical intervention and possibly mortality in upper GI bleeding, current guidelines do not recommend its routine use, as stated by the American Gastroenterological Association 1, 2
The standard of care for upper GI bleeding remains prompt endoscopic evaluation and therapy, followed by high-dose proton pump inhibitor therapy, as recommended by the American College of Physicians 3
For patients with active bleeding that cannot be controlled endoscopically, surgical intervention is indicated rather than relying on pharmacologic therapy alone, according to the American Gastroenterological Association 1, 2

Many studies on TXA for GI bleeding are considered historic and were conducted before the routine use of high-dose acid suppression and modern endoscopic therapy 6
The British Society of Gastroenterology suggests that use of tranexamic acid in acute lower GI bleeding should be confined to clinical trials 7, 6
Studies have been too small to adequately assess the effect of tranexamic acid on thromboembolic events in the context of GI bleeding 6

When TXA is used in trauma settings, it should be administered as soon as possible, with a loading dose of 1g over 10 minutes, followed by an intravenous infusion of 1g over 8 hours 8

Loading dose: 1g IV over 10 minutes 8
Maintenance: 1g IV over 8 hours 8
Administration should ideally be within 3 hours of bleeding onset for maximum benefit 8
