Dosing Considerations
Hepatic Impairment

Specific guidelines for dosage adjustments in hepatic impairment are not available; it appears that no dosage adjustments are needed.

Renal Impairment

Oral tranexamic acid (e.g., Lysteda):
SCr 1.4 mg/dL or less: No dosage adjustment needed.
SCr 1.5 to 2.8 mg/dL: 1,300 mg PO twice daily for a maximum of 5 days during menstruation.
SCr 2.9 to 5.7 mg/dL: 1,300 mg PO once daily for a maximum of 5 days during menstruation.
SCr more than 5.7 mg/dL: 650 mg PO once daily for a maximum of 5 days during menstruation.[37613]
 
Intravenous tranexamic acid (e.g., Cyklokapron):

Drug Interactions

Alteplase: (Contraindicated) Antifibrinolytic agents, including tranexamic acid, can antagonize the actions of thrombolytic agents. Although antifibrinolytic agents can be beneficial in the treatment of thrombolytic-induced hemorrhage, the safety of concomitant administration of these agents has not been confirmed.
Anti-inhibitor Coagulant Complex: (Major) Use of tranexamic acid within approximately 6 to 12 hours after the administration of anti-inhibitor coagulant complex (human) is not recommended, due to the increased risk of thrombosis.
Conjugated Estrogens: (Contraindicated) Tranexamic acid is contraindicated in women who are using combination hormonal contraception containing an estrogen and a progestin. Use with other estrogens is also not recommended. Estrogens increase the hepatic synthesis of prothrombin and factors VII, VIII, IX, and X and decrease antithrombin III; estrogens also increase norepinephrine-induced platelet aggregability. A positive relationship of estrogens to thromboembolic disease has been demonstrated, and the US FDA has suggested class labeling of combined OCs and non-oral combination contraceptives in accordance with this data. OC products containing >= 50-mcg ethinyl estradiol are associated with the greatest risk of thromboembolic complications. Therefore, do not coadminister estrogens, combined hormonal oral contraceptives, or non-oral combination contraceptives together with tranexamic acid. Tranexamic acid is an antifibrinolytic agent, and concomitant use can further exacerbate the thrombotic risk associated with these estrogen-containing hormonal products; in post-market use of tranexamic acid, cases of thromboembolic events have been reported, with cases occurring in those patients concomitantly receiving combined hormonal contraceptives containing both an estrogen and a progestin.

Lithium: (Moderate) Moderate to significant dietary sodium changes, or changes in sodium and fluid intake, may affect lithium excretion. Systemic sodium chloride administration may result in increased lithium excretion and therefore, decreased serum lithium concentrations. In addition, high fluid intake may increase lithium excretion. For patients receiving sodium-containing intravenous fluids, symptom control and lithium concentrations should be carefully monitored. It is recommended that patients taking lithium maintain consistent dietary sodium consumption and adequate fluid intake during the initial stabilization period and throughout lithium treatment. Supplemental oral sodium and fluid should be only be administered under careful medical supervision.

Mechanism Of Action

Tranexamic acid is a hemostatic agent and is a synthetic derivative of the amino acid lysine. Tranexamic acid binds to the lysine binding site for fibrin on the plasminogen/plasmin molecule. Plasminogen has 4 to 5 binding sites with low affinity for tranexamic acid and 1 high-affinity binding site. The high-affinity binding site is involved with the binding of plasminogen to fibrin. Saturation of this high-affinity binding site by tranexamic acid displaces plasminogen from the surface of fibrin. This prevents the binding of fibrin to plasmin and preserves and stabilizes the matrix structure of fibrin and diminishes the ability of plasmin to lyse fibrin clots. Tranexamic acid is about 10 times more potent in vitro than aminocaproic acid, binding more strongly to both the high and low-affinity binding sites of plasminogen.
 
Elevated concentrations of endometrial, uterine, and menstrual blood tissue plasminogen activator (tPA) are observed in women with heavy menstrual bleeding compared to women with normal menstrual blood loss. In women with heavy menstrual bleeding and after receiving oral doses of 2 to 3 g/day for 5 days, the effect of tranexamic acid on lowering endometrial tPA concentrations and menstrual fluid fibrinolysis is observed.
 
At blood concentrations as low as 1 mg/mL, tranexamic acid can prolong the thrombin time. However, at blood concentrations up to 10 mg/mL, tranexamic acid has no effect on platelet count, coagulation time, or various coagulation factors in whole blood or citrated blood in healthy subjects.

Pharmacokinetics

Tranexamic acid is administered orally and intravenously. Tranexamic acid is minimally bound to plasma proteins (3%) and binds exclusively to plasminogen (no apparent binding to albumin).[37613] [56752] Apparent steady-state Vd is 0.39 L/kg.[37613] Tranexamic acid distributes into various tissues. It diffuses rapidly into joint fluid and the synovial membrane. Concentrations in the joint fluid are similar to those seen in the serum.[56752] It is also distributed in both the cerebrospinal fluid and the aqueous humor of the eye at one-tenth the plasma concentration.[37613] [56752] Only a small amount of tranexamic acid is metabolized. Tranexamic acid is eliminated by urinary excretion primarily via glomerular filtration. Overall clearance is equivalent to plasma clearance (110 to 116 mL/minute) with more than 95% of the dose excreted unchanged.[37613] [56752] The biological half-life of tranexamic acid in synovial fluid is approximately 3 hours.[56752] The elimination half-life of tranexamic acid is approximately 2 hours, and the mean terminal half-life is approximately 11 hours.[37613] Antifibrinolytic concentrations remain in tissues for about 17 hours and in the serum for 7 to 8 hours.[56752]
 
Affected cytochrome P450 isoenzymes and drug transporters: none

Oral Route

Peak plasma concentration is attained approximately 3 hours after a single oral dose. Absolute bioavailability is approximately 45%. Cmax increases approximately 19% after 5 days of multiple doses (13.83 to 16.41 mcg/mL), while AUC remains unchanged (77.96 and 77.67 mcg/mL x hour). Food does not significantly affect absorption. At in vitro concentrations of 25 to 100 micromolar, tranexamic acid reduces the maximal rate of plasmin lysis of fibrin catalyzed by tissue plasminogen activator (tPA) by 20% to 60%. After receiving oral doses of 2 to 3 g/day for 5 days, endometrial tPA concentrations are lowered and menstrual fluid fibrinolysis is observed in women with heavy menstrual bleeding.[37613]

Intravenous Route

After an intravenous dose of 10 mg/kg, excretion of tranexamic acid is approximately 90% at 24 hours, with most elimination occurring during the first 10 hours.

Pregnancy And Lactation
Pregnancy

Available data with tranexamic acid use in pregnant women in the second and third trimesters and at the time of delivery have not clarified whether there is a drug-associated risk of miscarriage or adverse maternal or fetal outcomes. Tranexamic acid is known to pass the placenta and appears in cord blood at concentrations approximately equal to maternal concentration. Clinical studies in fetuses and infants exposed to tranexamic acid in utero describe fetal and/or neonatal functional issues, such as low Apgar score, neonatal sepsis, cephalohematoma, and alterations to growth, including low birth weight and preterm birth at 22 to 36 weeks of gestation. Also, there are 2 (0.02%) infant cases with structural abnormalities that resulted in death when tranexamic acid was used during conception or the first trimester of pregnancy; however, due to other confounding factors, the risk of major birth defects with the use of tranexamic acid during pregnancy is not clear. Consider the potential risk of tranexamic acid administration on the fetus along with the mother's clinical need for tranexamic acid during pregnancy; an accurate risk-benefit evaluation should drive the decision to use tranexamic acid.[56752]

Tranexamic acid is present in the mother's milk at a concentration about one-hundredth of the corresponding serum concentration. The amount of tranexamic acid a breast-feeding infant would absorb is not known. There are no data available on the effects of tranexamic acid on the breast-fed infant or milk production. Consider the developmental and health benefits of breast-feeding along with the mother's clinical need for tranexamic acid and any potential adverse effects on the breast-fed infant from tranexamic acid or the underlying maternal condition. [56752] An international consensus panel recommends against using tranexamic acid during breast-feeding in patients with hereditary angioedema caused by C1 inhibitor deficiency.[48655]
