Tranexamic has a hemostatic, anti-inflammatory, anti-allergic effect.
Tranexamic acid is an antifibrinolytic agent specifically inhibiting the activation of profibrinolysin (plasminogen) and its conversion into fibrinolysin (plasmin).
It has local and systemic hemostatic action in bleeding associated with increased fibrinolysis as well as anti-inflammatory, anti-allergic, anti-infective and
anti-tumor action due to suppression of formation of kinins and other active peptides involved in allergic and inflammatory reactions.
The intrinsic analgesic activity of tranexamic acid was confirmed in the experiment, as well as the supersumptive andotensive effect with respect to the analgesic activity of opiates.
Pharmacokinetics
The distribution in tissues is relatively uniform (exception is cerebrospinal fluid, where the concentration is 1/10 of the plasma concentration); penetrates through the placental and blood-brain barrier,
into breast milk (about 1% of the concentration in maternal plasma). It is found in seminal fluid, where it reduces fibrinolytic activity, but does not affect sperm migration.
The initial volume of distribution is 9-12 liters. Binding with plasma proteins (profibrinolysin) is less than 3%. In the blood about 3% is bound to protein (plasminogen).
The concentration in cerebrospinal fluid is 1/10 of plasma. Total renal clearance is equal to plasma clearance. Antifibrinolytic concentration in various tissues persists for 17 hours, in plasma – up to 7-8 hours.
A small part is metabolized. The concentration-time curve has a three-phase shape with a half-life of -2 hours in the terminal phase. Total renal clearance is equal to plasma clearance (7 l/h).
Extracted by the kidneys (main route – glomerular filtration) – more than 95% unchanged in the first 12 hours.
Two metabolites of tranexamic acid have been identified: N-acetylated and deaminated derivatives. There is a risk of cumulation of tranexamic acid in impaired renal function.
Indications
Short-term treatment of bleeding associated with increased fibrinolysis in the following pathological conditions: Prostatectomy; surgical interventions on the bladder; Menorrhagia; Nosebleed; Conization of the cervix; Traumatic hyphema (hemorrhage into the anterior chamber of the eye). Prevention and treatment of bleeding in patients with hemophilia who undergo minor surgery (including tooth extraction). Hereditary angioedema (prevention of exacerbations of the disease). Bleeding during pregnancy.
Pharmacological effect
Tranexam has a hemostatic, anti-inflammatory, antiallergic effect.
Tranexamic acid is an antifibrinolytic agent that specifically inhibits the activation of profibrinolysin (plasminogen) and its conversion to fibrinolysin (plasmin).
It has a local and systemic hemostatic effect in case of bleeding associated with increased fibrinolysis, as well as anti-inflammatory, anti-allergic, anti-infective and
antitumor effects due to suppression of the formation of kinins and other active peptides involved in allergic and inflammatory reactions.
The experiment confirmed the intrinsic analgesic activity of tranexamic acid, as well as the super-total ioteniating effect on the analgesic activity of opiates.
Pharmacokinetics
Distributed relatively evenly in tissues (with the exception of cerebrospinal fluid, where the concentration is 1/10 of the plasma concentration); penetrates the placental and blood-brain barrier,
into breast milk (about 1% of the concentration in maternal plasma). It is found in seminal fluid, where it reduces fibrinolytic activity, but does not affect sperm migration.
The initial volume of distribution is 9-12 l. Communication with plasma proteins (profibrinolysin) – less than 3%. In the blood, about 3% is associated with protein (plasminogen).
The concentration in the cerebrospinal fluid is 1/10 of the plasma concentration. Total renal clearance is equal to plasma clearance. Antifibrinolytic concentration in various tissues lasts 17 hours, in plasma – up to 7-8 hours.
A small part is metabolized. The concentration-time curve has a triphasic shape with a half-life in the terminal phase of -2 hours. Total renal clearance is equal to plasma (7 l/h).
Excreted by the kidneys (the main route is glomerular filtration) – more than 95% unchanged during the first 12 hours.
Two metabolites of tranexamic acid have been identified: N-acetylated and deaminated derivatives. In case of impaired renal function, there is a risk of accumulation of tranexamic acid.
Special instructions
In patients with hereditary angioedema, before starting treatment, consultation with an ophthalmologist is necessary (determining visual acuity, color vision, condition of the fundus). During treatment, regular ophthalmological examination is necessary (including assessment of visual acuity and color perception, examination of the fundus with a slit lamp, measurement of intraocular pressure, assessment of visual fields). If visual impairment occurs during treatment with tranexamic acid, the drug must be discontinued. In patients with hereditary angioedema who have been receiving tranexamic acid for a long time, regular laboratory monitoring of liver function is necessary. Tranexamic acid preparations should be used with caution in hematuria caused by diseases of the renal parenchyma, since intravascular fibrin deposition is often observed in these conditions, which can aggravate renal damage. In addition, in cases of massive bleeding of any etiology from the upper urinary tract, antifibrinolytic therapy increases the risk of blood clots in the renal pelvis and/or ureter and, accordingly, secondary mechanical obstruction of the urinary tract and the development of anuria. Although clinical studies have not revealed a significant increase in the incidence of thrombosis, the risk of thrombotic complications cannot be completely excluded. Cases of the development of venous and arterial thrombosis and thromboembolism in patients receiving tranexamic acid have been described. In addition, cases of occlusion of the central retinal artery and central retinal vein have been reported. Several patients developed intracranial thrombosis during treatment with tranexamic acid. Accordingly, in patients with a high risk of developing thrombosis (history of thromboembolic complications, cases of thromboembolism in relatives, verified diagnosis of thrombophilia), tranexamic acid should be used only if absolutely necessary and under strict medical supervision. Before using tranexamic acid, an examination should be performed to identify risk factors for thromboembolic complications. The presence of blood in cavities, such as the pleural cavity, joint cavities and urinary tract (including the renal pelvis and bladder) can lead to the formation of an “insoluble clot” due to extravascular coagulation, which may be resistant to physiological fibrinolysis. Patients with irregular menstrual bleeding should not be prescribed tranexamic acid until the cause of dysmenorrhea is determined. If the amount of menstrual bleeding is inadequately reduced during treatment with tranexamic acid, alternative treatment should be considered. There is insufficient data on the effectiveness and safety of the use of tranexamic acid in the treatment of menorrhagia in patients under 15 years of age, so the drug should be used with caution. Tranexamic acid should be used with caution in women concomitantly taking combined oral contraceptives due to the increased risk of thrombosis (See section “Interaction with other drugs”). In patients with DIC who require treatment with tranexamic acid, therapy should be carried out under the close supervision of a physician experienced in treating this disease. Due to the lack of adequate clinical studies, the simultaneous use of tranexamic acid with anticoagulants should be under the close supervision of a specialist experienced in the treatment of bleeding disorders. If vision impairment occurs while taking tranexamic acid, you should stop taking the drug and consult a doctor.

Pregnancy
In preclinical studies, tranexamic acid did not have a teratogenic effect. Adequate and strictly controlled studies of the effectiveness and safety of tranexamic acid in pregnant women have not been conducted. Tranexamic acid crosses the placenta and may be present in cord blood in concentrations close to maternal levels. Because animal reproduction studies do not always predict reactions in humans, tranexamic acid should be used during pregnancy only when absolutely necessary. Tranexamic acid passes into breast milk (the concentration of the drug in milk is about 1% of the concentration in the mother’s blood plasma). The development of an antifibrinolytic effect in an infant is unlikely. However, caution should be exercised when using tranexamic acid in nursing mothers.
