Composition

Active ingredient: dl-alpha-Tocopherol acetate - 300 g;
excipients: sunflower oil (refined deodorized "First grade") - up to 1 l.

Description of the dosage form

Transparent oily liquid from light yellow to dark yellow color without a rancid smell. A greenish tint is permissible.

Contraindications

Hypersensitivity to the drug, severe atherosclerosis of the coronary arteries, myocardial infarction, increased risk of thromboembolism.

With caution:

Hypoprothrombinemia (against the background of vitamin K deficiency - may be exacerbated with a dose of vitamin E over 400 IU).

Pregnancy and lactation:

As recommended by a doctor.

Special instructions

Tocopherols are found in the green parts of plants, especially in the young shoots of cereals; large amounts of tocopherols are found in vegetable oils (sunflower, cottonseed, corn, peanut, soybean, sea buckthorn). Some amount is present in meat, fat, eggs, and milk.

It should be noted that newborns with low birth weight may experience vitamin E deficiency due to the low permeability of the placenta (the blood of the fetus contains only 20-30% of the vitamin E concentration found in the mother's blood).

Effect on the ability to drive vehicles and operate machinery:
No effect.

Side effects

Possible allergic reactions.

Section: Overdose

Symptoms: with prolonged intake in doses of 400-800 IU/day (1 mg = 1.21 ME) - blurred vision, dizziness, headache, nausea, unusual fatigue, diarrhea, abdominal pain, asthenia; with intake of more than 800 IU/day for an extended period - increased risk of bleeding in patients with vitamin K deficiency, disruption of thyroid hormone metabolism, sexual function disorders, thrombophlebitis, thromboembolism, necrotizing colitis, sepsis, hepatomegaly, hyperbilirubinemia, renal failure, retinal hemorrhage, hemorrhagic stroke, ascites.

Treatment - symptomatic, discontinuation of the drug, administration of glucocorticoids.

Interaction

Enhances the effect of glucocorticosteroids and non-steroidal anti-inflammatory drugs, antioxidants. Increases the effectiveness and reduces the toxicity of vitamins A, D, and cardiac glycosides.

The administration of vitamin E in high doses may cause a deficiency of vitamin A in the body. Cholestyramine, colestipol, and mineral oils reduce the absorption of alpha-tocopherol acetate. High doses of iron enhance oxidative processes in the body, which increases the need for vitamin E.

Simultaneous use of vitamin E at a dose of more than 400 mg/day with anticoagulants (derivatives of coumarin and indandione) increases the risk of developing hypoprothrombinemia and bleeding.

When used simultaneously with cyclosporine, the absorption of the latter is increased.

Section: Pharmacodynamics

Fat-soluble vitamin. It has antioxidant properties (removes toxins from the body), prevents the formation of peroxides (removes and limits their formation from membrane lipids), provides protection for unsaturated fatty acids; participates in the formation of intercellular substance, collagen and elastic fibers of connective tissue, smooth muscle of blood vessels, and the digestive tract. It restores impaired capillary blood circulation, normalizes capillary and tissue permeability, and increases tissue resistance to hypoxia.

Pharmacokinetics

Absorption from the duodenum (requires the presence of bile salts, fats, normal pancreatic function) - 50-80%. Binds to beta-lipoproteins in the blood. In cases of protein metabolism disorders, transport is hindered. T max - 4 hours. Deposited in all organs and tissues, especially in adipose tissue. Passes through the placenta in insufficient amounts: 20-30% of the concentration in the mother's blood penetrates into the fetal blood. Enters breast milk. Metabolized in the liver to derivatives with a quinone structure (some of which have vitamin activity). Excreted in bile - more than 90% (some amount is reabsorbed and undergoes enterohepatic circulation), kidneys - 6% (in the form of glucuronides of tocopheronic acid and its gamma-lactone). Excreted slowly, especially in premature and newborn infants, where accumulation may occur.

Alpha-tocopherol acetate, known as vitamin E, is a fat-soluble vitamin.

This medication is recommended to be taken according to the doctor's prescription or instructions. Allergic reactions may occur.
