Pharmacology
Indication For use in patients with hemophilia for short term use (two to eight days) to reduce or prevent hemorrhage and reduce the need for replacement therapy during and following tooth extraction. It can also be used for excessive bleeding in menstruation, surgery, or trauma cases.
Mechanism of action Tranexamic acid competitively inhibits activation of plasminogen (via binding to the kringle domain), thereby reducing conversion of plasminogen to plasmin (fibrinolysin), an enzyme that degrades fibrin clots, fibrinogen, and other plasma proteins, including the procoagulant factors V and VIII. Tranexamic acid also directly inhibits plasmin activity, but higher doses are required than are needed to reduce plasmin formation.
Absorption Absorption of tranexamic acid after oral administration in humans represents approximately 30 to 50% of the ingested dose and bioavailability is not affected by food intake.
Protein binding The plasma protein binding of tranexamic acid is about 3% at therapeutic plasma levels and seems to be fully accounted for by its binding to plasminogen (does not bind serum albumin).
Biotransformation Only a small fraction of the drug is metabolized (less than 5%).
Route of elimination Urinary excretion is the main route of elimination via glomerular filtration.
Toxicity Oral LD50 in mice is >10 gm/kg. Symptoms of overdosage may be nausea, vomiting, orthostatic symptoms and/or hypotension.
