Tranexamic Acid Chemical Properties, Uses, Production
Description
Tranexamic acid is a derivative of aminomethylbenzoic acid, and a kind of antifibrinolytic drugs to stop bleeding. The hemostasis mechanism of tranexamic acid is similar to aminocaproic acid and aminomethylbenzoic acid, but the effect is stronger. The strength is 7 to 10 times of aminocaproic acid, 2 times of aminomethylbenzoic acid, but toxicity is similar.
The chemical structure of tranexamic acid is similar to lysine, competitive inhibition of plasmin original in fibrin adsorption, to prevent their activation, protection fiber protein not to degrade by plasmin and dissolve, eventually achieve hemostasis. Applicable in the treatment of acute or chronic, localized or systemic primary fiber fibrinolytic hyperthyroidism caused by bleeding, such as obstetric hemorrhage, renal hemorrhage, hemorrhage of hypertrophy of the prostate, hemophilia, pulmonary tuberculosis hemoptysis, stomach bleeding, after operation of liver, lung, spleen and other viscera hemorrhage; also can be used in surgery when abnormal bleeding etc..
Clinical tranexamic acid has effect significantly to insect bites disease, dermatitis and eczema, simple purpura, chronic urticaria, artificial sex urticaria, toxic eruption and eruption. And also has a certain effect on erythroderma, scleroderma, systemic lupus erythematosus (SLE), Erythema multiforme, shingles and alopecia areata. Treatment of hereditary angioedema effect is also good. In the treatment of Chloasma, general medicine is effective about 3 weeks, markedly effective 5 weeks, a course of 60 days. Given orally in doses of 0.25 ~ 0.5 g, a day 3 ~ 4 times. A few patients can nausea, fatigue, pruritus, abdominal discomfort, and diarrhea side effects after withdrawal symptoms disappear.
Chemical Properties
Tranexamic acid is a White or almost white, crystalline powder. It is freely soluble in water and in glacial acetic acid and is very slightly soluble in ethanol and practically insoluble in ether.
Originator
Anvitoff,Knoll,W. Germany,1967
Uses
Fibrinolysis, the cleavage of fibrin by plasmin, is a normal step in the dissolution of fibrin clots after wound repair. Tranexamic acid is an inhibitor of fibrinolysis that blocks the interaction of plasmin with fibrin (IC50 = 3.1 μM). It is a lysine mimetic that binds the lysine binding site in plasmin. Antifibrinolytic agents have value when fibrinolytic activity is abnormally high or when coagulation is impaired.
Indications
Various bleedings caused by acute or chronic, localized or systemic primary hyperfibrinolysis; secondary hyperfibrinolytic state caused by disseminated intravascular coagulation. Generally do not use this product before heparinization.
Trauma or surgical bleeding in tissue and organs with abundant plasminogen activators such as prostate, urethra, lung, brain, uterus, adrenal glands, and thyroid.
An antagonist of tissue plasminogen activator (t-PA), streptokinase, and urokinase.
Fibrinolytic hemorrhage caused by artificial abortion, early placental detachment, stillbirth and amniotic fluid embolism; and increased menorrhagia caused by pathological intrauterine fibrinolysis.
Cerebral neuropathy mild bleeding, such as subarachnoid hemorrhage and intracranial aneurysm hemorrhage, the effect of Amstat in this condition is better than that of other anti-fibrinolytic agents. Special attention must be paid to the risk of cerebral edema or cerebral infarction.For severe patients with surgical indications, this product can only be used as an adjuvant drug.
For the treatment of hereditary angioneurotic edema, it can reduce the number and severity of episodes.
Used in patients with hemophilia for their active hemorrhage in combination with others drug.
Hemophilia patients with factor VIII or factor IX deficiency in their tooth extraction or oral surgery in case of operating bleeding.
Definition
ChEBI: Tranexamic acid is a monocarboxylic acid. It has a role as an antifibrinolytic drug and a hematologic agent. It is functionally related to a cyclohexanecarboxylic acid.
Manufacturing Process
In an autoclave, 2 grams of a mixture of cis- and trans-4- aminomethylcyclohexane-1-carboxylic acid, which is obtained by catalytic reduction of p-aminomethylbenzoic acid in the presence of platinum catalyst and contains 60% by weight of cis-isomer was reacted at 200°C, for 8 hours with 20 ml of ethyl alcohol in which 0.44 gram of sodium metal had been dissolved. After cooling, the reaction solution was concentrated under a reduced pressure to give a white residue. This residue was dissolved in 40 ml of water and passed through a column of a strongly acidic cation ion_x0002_exchanger resin (NH4+). The eluate was concentrated under reduced pressure to form a white mass. An adequate amount of acetone was added thereto and 1.95 grams of white powder was obtained. This powder was recrystallized from water-acetone to give 1.85 grams (yield, 92.5%) of white crystalline powder having a melting point of 380° to 390°C (decomposition). This product was identified as trans-4-aminomethylcyclohexane-1-carboxylic acid by means of infrared spectrum.
Therapeutic Function
Coagulant
General Description
Tranexamic acid is an antifibrinolytic agent and is commonly used for heavy menstrual bleeding.
Mechanism of action
Tranexamic acid is a 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 fibrin’s matrix structure. This agent has a longer half-life, is approximately ten times more potent, and is less toxic than aminocaproic acid, which possesses similar mechanisms of action.
Clinical Use
Haemostatic agent
Side effects
Tranexamic acid is mostly well-tolerated.
Common
nausea (upset stomach)
vomiting (throwing up)
diarrhea
headache
Occasional
dizziness
giddiness
vision changes
Rare
stroke
blood clots in undesired areas
deep vein thrombosis
Synthesis
Tranexamic acid, trans-4-(aminomethyl)cyclohexane carboxylic acid (24.4.5), is synthesized from 4-methylbenzonitrile. Oxidation of the methyl group gives the mononitrile of terephthalic acid 24.4.2. The cyano group in this compound is reduced by hydrogen using Raney nickel as a catalyst. The benzene ring of the resulting 4- aminomethylbenzoic acid (24.4.3) is reduced to a cyclohexane moiety by hydrogen and a platinum catalyst, which forms an isomeric mixture of 4-aminomethylcyclohexane carboxylic acids (24.4.4), and the desired trans-isomer 24.4.5 is isolated by crystallization of the mixture of its sodium salts.
target
GABA Receptor
Metabolism
Tranexamic acid is excreted as unchanged drug mainly by urinary excretion via glomerular filtration.
Pharmacokinetics
Tranexamic acid 1 g was given intravenously to three healthy volunteers. Plasma concentrations decayed in three monoexponential phases. Most elimination occurred during the first eight hours, giving an apparent elimination half-life of approximately two hours. Plasma clearance ranged between 110-116 ml/min. The urinary recovery of tranexamic acid exceeded 95% of the dose. The oral bioavailability of tranexamic acid, calculated from 24-hour urinary excretion after oral and intravenous administration, was 34% of the dose[1].
