Tranexamic acid - Wikipedia, the free encyclopedia

Tranexamic acid is a synthetic analog of the amino acid lysine. It is used to treat or prevent excessive blood loss during surgery and in various medical.

Tranexamic acid is marketed in the U.S. and Australia in tablet form as Lysteda and in IV form as Cyklokapron and Transamin, in the UK as Cyclo-F and Femstrual, in Asia as Transcam, in Bangladesh as Traxyl, in South America as Espercil, in Japan as Nicolda, in France and Romania as Exacyl and in Egypt as Kapron.In the Philippines, its capsule form is marketed as Hemostan. M : MYL.

TXA has been included in the WHO list of essential medicines. TXA is inexpensive and treatment would be considered highly cost effective in high, middle and low income countries.

Tranexamic acid is used in orthopedic surgery to reduce blood loss, to the extent of reducing or altogether abolishing the need for perioperative blood collection.

Mechanism of Action. Tranexamic acid is a synthetic lysine amino acid derivative, which diminishes the dissolution of hemostatic fibrin by plasmin.

The effect of LYSTEDA on QT interval was evaluated in a randomized, single-dose, 4-way crossover study in 48 healthy females aged 18 to 49 years. Subjects received (1) LYSTEDA 1300 mg (two 650 mg tablets), (2) LYSTEDA 3900 mg (six 650 mg tablets; three times the recommended single dose), (3) moxifloxacin 400 mg, and (4) placebo. There was no significant increase in the corrected QT interval at any time up to 24 hours after the administration of either dose of LYSTEDA. Moxifloxacin, the active control, was associated with a maximum 14.11 msec mean increase in corrected QT interval (moxifloxacin – placebo) at 3 hours after administration.

Tranexamic acid for trauma patients a critical review of the literature

Mechanism
Tranexamic acid for trauma patients a critical review of the literature

BACKGROUND: Tranexamic acid (TXA) is an antifibrinolytic that inhibits both Further research on possible alternate mechanisms of action and dosing.

Tranexamic acid (TXA) is an antifibrinolytic that inhibits both plasminogen activation and plasmin activity, thus preventing clot break-down rather than promoting new clot formation. TXA has been used around the world to safely control bleeding since the 1960s. A large randomized trial recently conducted in >20,000 trauma patients adds to the large body of data documenting the usefulness of TXA in promoting hemostasis.

This inexpensive and safe drug should be incorporated into trauma clinical practice guidelines and treatment protocols. Further research on possible alternate mechanisms of action and dosing regimens for TXA should be undertaken. Concurrent to these endeavors, TXA should be adopted for use in bleeding trauma patients because it is the only drug with prospective clinical evidence to support this application.

TXA has been safely used across a wide range of clinical settings to control hemorrhage. The results of a large, randomized, placebo-controlled trial support the use of TXA to treat bleeding trauma patients.

We reviewed the literature describing use of TXA in a variety of settings including trauma.
