pharmachologic effect

A group of antimetabolites, in which the analogue is folic acid. It has an antitumor effect and additionally has an immunosuppressive effect.
The medicine slows DNA repair and its synthesis, inhibits the mitosis of cells. The influence of Methotrexate is most sensitive to tissues that are capable of high proliferation: tumor tissue, embryonic cells, bone marrow, epithelium of mucous membranes.
In the proliferation of malignant cells, which outstrips those in normal cells, Methotrexate leads to a disruption in the growth of malignant tumors without harming healthy tissues.
In the therapy of rheumatoid arthritis, the effect is presumably associated with the mechanism of immunosuppression. Methotrexate in rheumatoid arthritis can reduce inflammation and its symptoms - swelling, pain, stiffness.
In the treatment of psoriasis, Methotrexate acts on keratinocytes of plaques, in which the growth rate is increased in comparison with the normal proliferation of skin cells.

Pharmacodynamics and pharmacokinetics

The maximum concentration in the blood of Methotrexate occurs in 30-60 minutes. Patients with leukemia may have fluctuations of up to 3 hours.
In blood plasma binds to albumins. With simultaneous administration with salicylates, chloramphenicols, sulfonamides, tetracyclines, phenytoin, there may be a competitive substitution.
Methotrexate does not penetrate the blood-brain barrier, for this it must be administered intrathecally.
The half-life of Methotrexate is about 6-7 hours, in the case of high doses - increases to 17 hours.
It is excreted mainly (90%) by the kidneys during the day. About 10% is excreted with bile.
In the case of severe renal impairment, excretion is prolonged.
Methotrexate can accumulate in the liver, kidney and spleen as metabolic products.

Other side effects that may occur are: fever, malaise, chills, rarely - poor wound healing. In the case of intramuscular injection, there may be tissue damage at the site of administration (abscess, destruction), cysts and polyps, and lymphomas. An unknown frequency can cause metabolic disorders, diabetes.
In the case of intrathecal administration of Methotrexate, arachnoiditis (headache, rigidity of the neck muscles, fever) may sharply arise. In the future, there may be paresis and plethysm, a disorder of the cerebellar functions. Chronic reactions to intrathecal administration may be leukoencephalopathy, which is manifested by confusion, convulsions, dementia, coma, and rarely a fatal outcome.

Instructions for use Methotrexate (Method and dosage)

It is possible to administer Methotrexate - Ebwe intramuscularly, intraarterially, intravenously or intrathecally. Tablets are not chewed, before meals.
The instruction on Methotrexate warns that the choice of dose and treatment regimens for each specific pathology should be strictly in accordance with the special literature.
In the case of trophoblastic tumors, daily up to 30 mg of intramuscular injection is administered in 5 days. The courses are repeated after 1 week, until a dose of 400 mg is reached.
Lymphomas and leukemias suggest an intravenous injection of 200-500 mg per m2 once a month.
Neuroleukemia: injected intrathecally 1 - 2 times in 7 days at a dose of 12 mg per m2.
Children are prescribed the following doses:
    younger than 1 year of 6 mg;
    age 1 year - 8 mg;
    up to 2 years 10 mg are used;
    over 3 years, 12 mg are administered.
Methotrexate in rheumatoid arthritis is prescribed, starting at a dose of 7.5 mg, once a week. According to the indications, the dose is increased, but not more than 20 mg per week.
In psoriasis, a dose of up to 25 mg per week, intramuscularly or intravenously, is given.
With mushroom mycosis injected 50 mg per week once or in 2 divided doses, intramuscularly.


The main symptoms of overdose are signs of oppression of the hematopoiesis system. Antidote is calcium folinate, which is administered no later than 60 minutes, with the dose should be equal to or higher than the dose of Methotrexate. In severe cases, urine alkalization and hydration are used.
In case of exceeding the dose with intrathecal administration, along with the administration of an antidote, rapid drainage of cerebrospinal fluid is provided.


With alcohol abuse and the use of hepatotoxic drugs, the toxic effect of Methotrexate on the liver is increasing.
Simultaneous reception with leflunamide increases the incidence of pancytopenia and cases of hepatotoxicity.
Chloramphenicol, tetracycline for oral administration reduces the absorption of Methotrexate.
Ciprofloxacin, glycopeptides, penicillins, loop diuretics, phenylbutazone reduce the clearance of the drug in the kidneys, which increases its concentration in the blood and increases toxicity on the hematopoiesis.
Also the toxicity of Methotrexate is increased when used simultaneously with salicylates and non-steroidal anti-inflammatory drugs.
Chloramphenicol, sulfonamides, pyrimethamine have a negative effect on the bone marrow, so the combination with Methotrexate exacerbates hematologic disorders.
Trimethoprim and sulfamethoxazole, which cause folate deficiency, as well as hypolipidemic drugs and indirect anticoagulants, can increase the toxic effect of Methotrexate.
It is necessary to avoid during the treatment of increased consumption of coffee, tea and sugary drinks with caffeine, as the clearance of theophylline can decrease.
With simultaneous admission with cytostatics, the clearance of Methotrexate is reduced.
Combination with radiotherapy increases the likelihood of tissue necrosis.
Methotrexate inhibits the immune response to vaccination, and in the case of administration of live vaccines, severe antigenic reactions are likely.
The use of amiodarone contributes to the appearance of skin ulcers.
With the introduction of acyclovir and simultaneous use of Methotrexate, the risk of neurologic damage is intrathecal.
