Prevention and treatment of haemorrhages due to general or local fibrinolysis in adults and children from one year.
Specific indications include:
- Haemorrhage caused by general or local fibrinolysis such as:
| - Menorrhagia and metrorrhagia, - Gastrointestinal bleeding, - Haemorrhagic urinary disorders, further to prostate surgery or surgical procedures affecting the urinary tract, |
- Ear Nose Throat surgery (adenoidectomy, tonsillectomy, dental extractions),
- Gynaecological surgery or disorders of obstetric origin,
- Thoracic and abdominal surgery and other major surgical intervention such as cardiovascular surgery,
- Management of haemorrhage due to the administration of a fibrinolytic agent.
Posology
Adults
Unless otherwise prescribed, the following doses are recommended:
1. Standard treatment of local fibrinolysis:
0.5 g (1 ampoule of 5 ml) to 1 g (1 ampoule of 10 ml or 2 ampoules of 5 ml) Lunex by slow intravenous injection (= 1 ml/minute) two to three times daily
2. Standard treatment of general fibrinolysis:
1 g (1 ampoule of 10 ml or 2 ampoules of 5 ml) Lunex by slow intravenous injection (= 1 ml/minute) every 6 to 8 hours, equivalent to 15 mg/kg BW
Renal impairment
In renal insufficiency leading to a risk of accumulation, the use of Lunex is contraindicated in patients with severe renal impairment. For patients with mild to moderate renal impairment, the dosage of Lunex should be reduced according to the serum creatinine level:
| Serum creatinine | Dose IV | Administration | |
| μmol/l | mg/10 ml | ||
| 120 to 249 | 1.35 to 2.82 | 10 mg/kg BW | Every 12 hours |
| 250 to 500 | 2.82 to 5.65 | 10 mg/kg BW | Every 24 hours |
| > 500 | > 5.65 | 5 mg/kg BW | Every 24 hours |
Hepatic impairment
No dose adjustment is required in patients with hepatic impairment.
Paediatric Population:
The efficacy, posology and safety of Lunex in children undergoing cardiac surgery have not been fully established.
Elderly:
No reduction in dosage is necessary unless there is evidence of renal failure.
Method of administration
The administration is strictly limited to slow intravenous injection.
Posology
Adults
Unless otherwise prescribed, the following doses are recommended:
1. Standard treatment of local fibrinolysis:
0.5 g (1 ampoule of 5 ml) to 1 g (1 ampoule of 10 ml or 2 ampoules of 5 ml) Lunexic acid by slow intravenous injection (= 1 ml/minute) two to three times daily
2. Standard treatment of general fibrinolysis:
1 g (1 ampoule of 10 ml or 2 ampoules of 5 ml) Lunexic acid by slow intravenous injection (= 1 ml/minute) every 6 to 8 hours, equivalent to 15 mg/kg BW
Renal impairment
In renal insufficiency leading to a risk of accumulation, the use of Lunexic acid is contraindicated in patients with severe renal impairment. For patients with mild to moderate renal impairment, the dosage of Lunexic acid should be reduced according to the serum creatinine level:
| Serum creatinine | Dose IV | Administration | |
| μmol/l | mg/10 ml | ||
| 120 to 249 | 1.35 to 2.82 | 10 mg/kg BW | Every 12 hours |
| 250 to 500 | 2.82 to 5.65 | 10 mg/kg BW | Every 24 hours |
| > 500 | > 5.65 | 5 mg/kg BW | Every 24 hours |
Hepatic impairment
No dose adjustment is required in patients with hepatic impairment.
Paediatric Population:
The efficacy, posology and safety of Lunexic acid in children undergoing cardiac surgery have not been fully established.
Elderly:
No reduction in dosage is necessary unless there is evidence of renal failure.
Method of administration
The administration is strictly limited to slow intravenous injection.
Acute venous or arterial thrombosis.
Fibrinolytic conditions following consumption coagulopathy except in those with predominant activation of the fibrinolytic system with acute severe bleeding.
Severe renal impairment (risk of accumulation).
History of convulsions
Intrathecal and intraventricular injection, intracerebral application (risk of cerebral oedema and convulsions)
The indications and method of administration indicated above should be followed strictly:
- Intravenous injections should be given very slowly.
- Lunex should not be administered by the intramuscular route.
Convulsions
Cases of convulsions have been reported in association with Lunex treatment.In coronary artery bypass graft (CABG) surgery, most of these cases were reported following intravenous (i.v.) injection of Lunex in high doses. With the use of the recommended lower doses of TXA, the incidence of post-operative seizures was the same as that in untreated patients.
Visual disturbances
Attention should be paid to possible visual disturbances including visual impairment, vision blurred, impaired colour vision and if necessary the treatment should be discontinued. With continuous long-term use of TXA solution for injection, regular ophthalmologic examinations (eye examinations including visual acuity, colour vision, fundus, visual field etc.) are indicated. With pathological ophthalmic changes, particularly with diseases of the retina, the physician must decide after consulting a specialist on the necessity for the long-term use of TXA solution for injection in each individual case.
Haematuria
In case of haematuria from the upper urinary tract, there is a risk for urethral obstruction.
Thromboembolic events
Before use of TXA, risk factors of thromboembolic disease should be considered. In patients with a history of thromboembolic diseases or in those with increased incidence of thromboembolic events in their family history (patients with a high risk of thrombophilia), Lunex solution for injection should only be administered if there is a strong medical indication after consulting a physician experienced in hemostaseology and under strict medical supervision.
Lunex should be administered with care in patients receiving oral contraceptives because of the increased risk of thrombosis.
Disseminated intravascular coagulation
Patients with disseminated intravascular coagulation (DIC) should in most cases not be treated with Lunex. If Lunex is given it must be restricted to those in whom there is predominant activation of the fibrinolytic system with acute severe bleeding. Characteristically, the haematological profile approximates to the following: reduced euglobulin clot lysis time; prolonged prothrombin time; reduced plasma levels of fibrinogen, factors V and VIII, plasminogen fibrinolysin and alpha-2 macroglobulin; normal plasma levels of P and P complex; i.e. factors II (prothrombin), VIII and X; increased plasma levels of fibrinogen degradation products; a normal platelet count. The foregoing presumes that the underlying disease state does not of itself modify the various elements in this profile. In such acute cases a single dose of 1 g Lunex is frequently sufficient to control bleeding. Administration of Lunex in DIC should be considered only when appropriate haematological laboratory facilities and expertise are available.

- Intravenous injections should be given very slowly.
- Lunexic acid should not be administered by the intramuscular route.

Healthcare professionals are asked to report any suspected adverse reactions via Yellow Card Scheme Website: www.mhra.gov.uk/yellowcard.
No case of overdose has been reported.
Signs and symptoms may include dizziness, headache, hypotension, and convulsions. It has been shown that convulsions tend to occur at higher frequency with increasing dose.
Management of overdose should be supportive.
Pharmacotherapeutic group: Antihemorrhagics, Antifibrinolytics, Aminoacids
ATC code: B02AA02
Lunex exerts an anti haemorrhagic activity by inhibiting the fibrinolytic properties of plasmin.
A complex involving Lunex, plasminogen is constituted; the Lunex being linked to plasminogen when transformed into plasmin.
The activity of the Lunex-plasmin complex on the activity on fibrin is lower than the activity of free plasmin alone.
In vitro studies showed that high tranexamic dosages decreased the activity of complement.
Paediatric population
In children over one year old:
Literature review identified 12 efficacy studies in paediatric cardiac surgery which have included 1073 children, 631 having received Lunex. Most of them were controlled versus placebo. Studied population was heterogenic in terms of age, surgery types, dosing schedules. Study results with Lunex suggest reduced blood loss and reduced blood product requirements in paediatric cardiac surgery under cardiopulmonary bypass (CPB) where there is a high risk of haemorrhage, especially in cyanotic patients or patients undergoing repeat surgery.The most adapted dosing schedule appeared to be:
- first bolus of 10 mg/kg after induction of anaesthesia and prior to skin incision,
- continuous infusion of 10 mg/kg/h or injection into the CPB pump prime at a dose adapted on the CPB procedure, either according to a patient weight with a dose of 10 mg/kg dose, either according to CPB pump prime volume, last injection of 10 mg/kg at the end of CPB.
While studied in very few patients, the limited data suggest that continuous infusion is preferable, since it would maintain therapeutic plasma concentration throughout surgery.
No specific dose-effect study or PK study has been conducted in children.

Absorption
Peak plasma concentrations of Lunex are obtained rapidly after a short intravenous infusion after which plasma concentrations decline in a multi-exponential manner.
Distribution
The plasma protein binding of Lunex is about 3% at therapeutic plasma levels and seems to be fully accounted for by its binding to plasminogen. Lunex does not bind to serum albumin. The initial volume of distribution is about 9 to 12 litres.
Lunex passes through the placenta. Following administration of an intravenous injection of 10 mg/kg to 12 pregnant women, the concentration of Lunex in serum ranged 10-53 μg/mL while that in cord blood ranged 4-31 μg/mL. Lunex diffuses rapidly into joint fluid and the synovial membrane. Following administration of an intravenous injection of 10 mg/kg to 17 patients undergoing knee surgery, concentrations in the joint fluids were similar to those seen in corresponding serum samples. The concentration of Lunex in a number of other tissues is a fraction of that observed in the blood (breast milk, one hundredth; cerebrospinal fluid, one tenth; aqueous humor, one tenth). Lunex has been detected in semen where it inhibits fibrinolytic activity but does not influence sperm migration.
Excretion
It is excreted mainly in the urine as unchanged drug. Urinary excretion via glomerular filtration is the main route of elimination. Renal clearance is equal to plasma clearance (110 to 116 mL/min). Excretion of Lunex is about 90% within the first 24 hours after intravenous administration of 10 mg/kg body weight. Elimination half-life of Lunex is approximately 3 hours.
Special populations
Plasma concentrations increase in patients with renal failure.
No specific PK study has been conducted in children.
