Hepatoprotective agent

Pharmacotherapeutic Group

Metabolic agent

Pharmacological Action

An essential amino acid necessary for maintaining body growth and nitrogen balance. It contains a methyl group, which is involved in the process of transmethylation and is necessary for the synthesis of choline. Through this, it normalizes the synthesis of phospholipids from fats and reduces the deposition of neutral fat in the liver.

It participates in the metabolism of sulfur-containing amino acids, in the synthesis of epinephrine, creatinine, and other biologically active substances, activates the action of hormones, vitamins (B12, ascorbic acid, folic acid), enzymes, proteins, and the reactions of transmethylation, deamination, and decarboxylation. It is necessary for the detoxification of xenobiotics.

In atherosclerosis, it reduces the concentration of cholesterol and increases the concentration of blood phospholipids.

Pharmacokinetics

Easily absorbed from the intestine. Excreted in the urine in small amounts.

Indications

As part of complex therapy for liver diseases occurring with fatty infiltration of hepatocytes: toxic hepatitis, hepatosis (including alcoholic), cirrhosis, liver dystrophy; intoxications.

Prevention of toxic liver damage caused by arsenic, chloroform, benzene, and alcohol.

As part of combination therapy: protein deficiency of various origins, atherosclerosis, diabetes mellitus.

Dosage Regimen

The method of application and dosage regimen for a specific drug depend on its form of release and other factors. The optimal dosage regimen is determined by the doctor. It is necessary to strictly adhere to the compliance of the dosage form of a specific drug with the indications for use and dosage regimen.

Administer tablets orally.

Determine the dose, frequency, and duration of therapy individually based on the indication, clinical situation, and patient age.

For adults, the recommended single dose is 0.5 to 1.5 grams.

For children over 6 years of age, the recommended single dose is 250 to 500 mg.

Take the prescribed dose three to four times daily.

Do not administer to children under 6 years of age; use is contraindicated in this age group.

In patients with renal impairment, use with caution due to the risk of increased hyperazotemia.

Prescribe in balance with other amino acids; unbalanced use in large doses may be damaging to hepatocytes and other organs.

When used concomitantly with levodopa, be aware that methionine may reduce its effectiveness.

Adverse Reactions

Possible allergic reactions.

In some cases nausea, vomiting (due to unpleasant odor and taste).

Contraindications

Hypersensitivity to methionine; severe hepatic insufficiency, hepatic encephalopathy, viral hepatitis; children under 6 years of age.

With caution renal failure (risk of increased hyperazotemia).

Use in Pregnancy and Lactation

During pregnancy, it should be used only after consultation with a doctor, in cases where the intended benefit to the mother outweighs the potential risk to the fetus.

If it is necessary to use during lactation, the issue of discontinuing breastfeeding should be decided.

Use in Renal Impairment

Use with caution in renal failure (risk of increased hyperazotemia).

Pediatric Use

Special Precautions

When methionine is used in patients with atherosclerosis, a decrease in blood cholesterol content and an increase in phospholipid levels have been noted.

It should be prescribed in balance with other amino acids. Unbalanced use of methionine in large doses can have a damaging effect on liver cells and other organs.

Drug Interactions

When used concomitantly with levodopa, its effectiveness is reduced.

Storage Conditions

Store at 2°C (36°F) to 25°C (77°F). Keep in original packaging, protected from light. Keep out of reach of children.
