Most common adverse reactions are nausea, vomiting, diarrhea, allergic dermatitis, giddiness, hypotension, and thromboembolic events (6).To report SUSPECTED ADVERSE REACTIONS, contact [Enter Company Name] or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Postmarketing Experience The following adverse reactions have been identified during postapproval use of tranexamic acid. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.Gastrointestinal disturbances (nausea, vomiting, diarrhea) may occur and may resolve with dose-reduction. Allergic dermatitis and giddiness have been reported. Hypotension has been reported when intravenous injection is too rapid.Thromboembolic events (e.g., deep vein thrombosis, pulmonary embolism, cerebral thrombosis, acute renal cortical necrosis, and central retinal artery, vein obstruction and cases associated with concomitant use of combination hormonal contraceptives) have been rarely reported in patients receiving tranexamic acid for indications other than hemorrhage prevention in patients with hemophilia. Convulsion, cromatopsia, and visual impairment have also been reported.Anaphylaxis or anaphylactoid reactions have been reported that are suggestive of causal relationship.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility An increased incidence of leukemia in male mice receiving tranexamic acid in food at concentration of 4.8% (equivalent to doses as high as g/kg/day) may have been related to treatment. Female mice were not included in this experiment.Hyperplasia of the biliary tract and cholangioma and adenocarcinoma of the intrahepatic biliary system have been reported in one strain of rats after dietary administration of doses exceeding the maximum tolerated dose for 22 months. Hyperplastic, but not neoplastic, lesions were reported at lower doses. Subsequent long-term dietary administration studies in different strain of rat, each with an exposure level equal to the maximum level employed in the earlier experiment, have failed to show such hyperplastic/neoplastic changes in the liver. No mutagenic activity has been demonstrated in several in vitro and in vivo test systems.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Tranexamic acid is synthetic lysine amino acid derivative, which diminishes the dissolution of hemostatic fibrin by plasmin. In the presence of tranexamic acid, the lysine receptor binding sites of plasmin for fibrin are occupied, preventing binding to fibrin monomers, thus preserving and stabilizing fibrins matrix structure.The antifibrinolytic effects of tranexamic acid are mediated by reversible interactions at multiple binding sites within plasminogen. Native human plasminogen contains to lysine binding sites with low affinity for tranexamic acid (Kd 750 umol/l) and with high affinity (Kd 1.1 umol/L). The high affinity lysine site of plasminogen is involved in its binding to fibrin. Saturation of the high affinity binding site with tranexamic acid displaces plasminogen from the surface of fibrin. Although plasmin may be formed by conformational changes in plasminogen, binding to and dissolution of the fibrin matrix is inhibited.. 12.2 Pharmacodynamics Tranexamic acid in concentrations of mg/mL and 10 mg/mL prolongs the thrombin time. An antifibrinolytic concentration of tranexamic acid remains in different tissues for about 17 hours, and in the serum, up to seven or eight hours.Tranexamic acid in concentrations up to 10 mg/mL blood has no influence on the platelet count, the coagulation time or various coagulation factors in whole blood or citrated blood from healthy subjects.. 12.3 Pharmacokinetics DistributionThe initial volume of distribution is about to 12 liters. 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. Tranexamic acid does not bind to serum albumin.EliminationAfter an intravenous dose of g, the plasma concentration time curve shows triexponential decay with half-life of about hours for the terminal elimination phase.ExcretionUrinary excretion is the main route of elimination via glomerular filtration. Overall renal clearance is equal to overall plasma clearance (110 to 116 mL/min) and more than 95% of the dose is excreted in the urine as the unchanged drug. Excretion of tranexamic acid is about 90% at 24 hours after intravenous administration of 10 mg/kg body weight.Specific PopulationsRenal ImpairmentThe effect of renal impairment on the disposition of Tranexamic Acid in Sodium Chloride Injection has not been evaluated. Urinary excretion following single intravenous injection of tranexamic acid declines as renal function decreases. Following single 10 mg/kg intravenous injection of tranexamic acid, the 24-hour urinary fractions of tranexamic acid with serum creatinine concentrations 1.4 2.8, 2.8 5.7, and greater than 5.7 mg/dL were 51, 39, and 19%, respectively. The 24-hour tranexamic acid plasma concentrations for these patients demonstrated direct relationship to the degree of renal impairment. Therefore, dose adjustment is needed in patients with renal impairment [see Dosage and Administration (2.2) and Use in Specific Populations (8.6)]. Drug Interaction StudiesNo studies of interactions between Tranexamic Acid in Sodium Chloride Injection and other drugs have been conducted.

PREGNANCY SECTION.

8.1 Pregnancy Risk SummaryAvailable data from published studies, case series and case reports with tranexamic acid use in pregnant women in the second and third trimester and at the time of delivery have not identified drug-associated risk of miscarriage or adverse maternal or fetal outcomes. There are no reports regarding the use of tranexamic acid during the first trimester of pregnancy; therefore, there are no data regarding the risk of major birth defects with use of tranexamic acid during pregnancy. However, tranexamic acid is known to pass the placenta and appears in cord blood at concentrations approximately equal to maternal concentration (see Data). Reproduction studies performed in mice, rats, and rabbits have not revealed any adverse effects on the fetus due to tranexamic acid.The estimated background risk for major birth defects and miscarriage for the indicated population is unknown. All pregnancies have background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in the clinically recognized pregnancies is 2-4% and 15-20%, respectively.DataHuman DataTranexamic acid passes through the placenta. The concentration in cord blood after an intravenous injection of 10 mg/ kg to pregnant women is about 30 mg/liter, as high as in the maternal blood.

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk SummaryAvailable data from published studies, case series and case reports with tranexamic acid use in pregnant women in the second and third trimester and at the time of delivery have not identified drug-associated risk of miscarriage or adverse maternal or fetal outcomes. There are no reports regarding the use of tranexamic acid during the first trimester of pregnancy; therefore, there are no data regarding the risk of major birth defects with use of tranexamic acid during pregnancy. However, tranexamic acid is known to pass the placenta and appears in cord blood at concentrations approximately equal to maternal concentration (see Data).

All pregnancies have background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in the clinically recognized pregnancies is 2-4% and 15-20%, respectively.DataHuman DataTranexamic acid passes through the placenta. The concentration in cord blood after an intravenous injection of 10 mg/ kg to pregnant women is about 30 mg/liter, as high as in the maternal blood.. 8.2 Lactation Risk SummaryPublished literature reports the presence of tranexamic acid in human milk. There are no data on the effects of tranexamic acid on the breastfed child or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for Tranexamic Acid in Sodium Chloride Injection and any potential adverse effects on the breastfed child from Tranexamic Acid in Sodium Chloride Injection or from the underlying maternal condition.. 8.3 Females and Males of Reproductive Potential ContraceptionConcomitant use of Tranexamic Acid in Sodium Chloride Injection, which is an antifibrinolytic, with hormonal contraceptives may increase the risk for thromboembolic adverse reactions. Advise patients to use an effective alternative (nonhormonal) contraceptive method [see Warnings and Precautions (5.5) and Drug Interactions (7.1)]. 8.4 Pediatric Use There are limited data concerning the use of tranexamic acid in pediatric patients with hemophilia who are undergoing tooth extraction. The limited data suggest that there are no significant pharmacokinetic differences between adult and pediatric patients.. 8.5 Geriatric Use Clinical studies of tranexamic acid did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function [Dosage and Administration (2.2) and Clinical Pharmacology (12.3)]. 8.6 Renal Impairment Reduce the dosage of Tranexamic Acid in Sodium Chloride Injection in patients with renal impairment, based on the patients serum creatinine [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3)].

Discontinue use if visual or ocular symptoms occur (5.4).oDizziness may occur. Advise patients not to drive if dizziness occurs (5.5).. oRisk of Thrombosis with concomitant use of Factor IX: Avoid concomitant use (5.1).. oSeizures: Inadvertent injection into neuraxial system may result in seizures (5.2).. oHypersensitivity Reactions: In case of severe reaction, discontinue use seek immediate medical attention (5.3).. oVisual Disturbances: Visual or ocular adverse effects may occur. Discontinue use if visual or ocular symptoms occur (5.4).. oDizziness may occur. Advise patients not to drive if dizziness occurs (5.5).. 5.1 Thromboembolic Risk Tranexamic Acid in Sodium Chloride Injection is contraindicated in patients with active intravascular clotting.Tranexamic acid is an antifibrinolytic and may increase the risk of thromboembolic events. Venous and arterial thrombosis or thromboembolism has been reported in patients treated with tranexamic acid. Avoid concomitant use of Tranexamic Acid in Sodium Chloride Injection and medical products that are pro-thrombotic, as the risk of thrombosis may be increased. These medications include, but are not limited to, Factor IX Complex concentrates, Anti-inhibitor Coagulant concentrates, and hormonal contraceptives [see Drug Interactions (7.1) and Use in Specific Populations (8.3)].. 5.2 Seizures Tranexamic acid may cause seizures, including focal and generalized seizures. The most common setting for tranexamic acid-induced seizures has been during cardiovascular surgery (a setting in which Tranexamic Acid in Sodium Chloride Injection is not FDA approved and which uses doses of up to ten-fold higher than the recommended human dose and in patients inadvertently given tranexamic acid into the neuraxial system). Tranexamic Acid in Sodium Chloride Injection is not approved and not recommended for neuraxial administration. Consider dose reduction during surgery and dose adjustments for patients with clinical conditions such as renal dysfunction. Closely monitor the patient during surgery. Consider EEG monitoring for patients with history of seizures or who experience myoclonic movements, twitching, or show evidence of focal seizures. Discontinue Tranexamic Acid in Sodium Chloride Injection if seizures occur.. 5.3 Hypersensitivity Reactions Cases of hypersensitivity reactions, including anaphylactic reactions, have occurred with use of intravenous tranexamic acid. Discontinue treatment with Tranexamic Acid in Sodium Chloride Injection if serious reaction occurs, provide appropriate medical management, and do not restart treatment. Tranexamic Acid in Sodium Chloride Injection is contraindicated in patients with history of hypersensitivity to tranexamic acid.. 5.4 Visual Disturbances Although not seen in humans, focal areas of retinal degeneration have been observed in cats, dogs and rats following oral or intravenous tranexamic acid at doses between 250 to 1600 mg/kg/day (6 to 40 times the recommended usual human dose) from days to year. No retinal changes have been observed in eye examinations of patients treated with tranexamic acid for up to years. Patients expected to be treated for greater than months may consider ophthalmic monitoring including visual acuity and optical coherence tomography at regular intervals. Discontinue Tranexamic Acid in Sodium Chloride Injection if changes in ophthalmological examination occurs.. 5.5 Dizziness Tranexamic acid may cause dizziness. Concomitant use of other drugs that may also cause dizziness may worsen this effect. Advise patients to avoid driving or using machines until they know how Tranexamic Acid in Sodium Chloride Injection affects them.
