During TXA administration, what is the specified rate and duration?

• A. 1 g in 100 mL Over 1 Minute
• B. 2 g in 100 mL, 10 drop-set, 3 drops a second over 5 minutes
• C. 2 g IV Bolus Over 1 Minute
• D. 5 g in 500 mL Over 30 Minutes

Answer: (B)

Dosing strategy and infusion rate for tranexamic acid are chosen to achieve a rapid, predictable antifibrinolytic effect without causing unsafe drug peaks. The best option administers 2 g in 100 mL as an IV infusion over 5 minutes using a controlled drip (3 drops per second). This delivers the full, effective dose quickly enough to aid hemostasis, while the controlled rate reduces the risk of high peak concentrations that could occur with a quick bolus and avoids delaying effect that would come with a slower, longer infusion. The other approaches either change the total dose, the method of administration, or the infusion duration in ways that would delay onset or increase risk, making them less appropriate for achieving prompt hemostasis.
