Vicasol, tablets 15 mg 20 pcs

Vicasol is a synthetic water-soluble analogue of vitamin K (vitamin K3), promotes the synthesis of prothrombin and proconvertin, increases blood clotting by increasing the synthesis of II, VII, IX, X clotting factors.

It has a hemostatic effect (with a deficiency of vitamin K occurs increased bleeding).

In the blood, prothrombin (factor II) in the presence of thromboplastin and calcium, with the participation of proconvertin (factor VII), factors IX (Christmass factor), X (Stuart-Prouwer factor) is converted into thrombin, which converts fibrinogen to fibrin, which is the basis of the blood clot (thrombus).

The substrate stimulates K-vitamin reductase, which activates vitamin K and ensures its participation in hepatic synthesis of K-vitamin-dependent plasma factors of hemostasis.

The onset of effect is 8 to 24 hours.

Pharmacokinetics

After intramuscular administration, it is easily and quickly absorbed. In small amounts it accumulates in tissues. Passing the cycle of metabolic activation, it is oxidized to the diol form.

It is excreted by the kidneys (up to 70%) and in the bile only as metabolites.

High concentrations of vitamin K in the feces are due to its synthesis by the intestinal microflora.

Indications

Active ingredient

Composition

Active ingredient:

15 mg sodium bisulfite menadione.

How to take, the dosage

Adults Vicasol is prescribed orally in 15-30 mg per day.

Children under 1 year of age – 2-5 mg per day, 1 to 2 years – 6 mg per day, 3-4 years – 8 mg per day, 5-9 years – 10 mg per day, 10-14 years – 15 mg per day. Frequency of administration – 2-3 times a day.

The maximum daily dose of the drug for newborns is 4 mg.

The duration of treatment is 3-4 days.

The course of treatment is repeated after a 4-day break.

Interaction

Antacids decrease absorption due to precipitation of bile acid salts in the initial part of the small intestine.

It does not affect the anticoagulant activity of heparin.

Concomitant administration with broad-spectrum antibiotics, quinidine, quinine, salicylates in high doses, antibacterial sulfonamides requires increasing the dose of vitamin K.

Colestyramine, colestipol, mineral oils, sucralfate, dactinomycin reduce absorption of vitamin K, which requires increasing its dose.

The concomitant administration with hemolytic drugs increases the risk of side effects

The concomitant administration with hemolytic drugs increases the risk of side effects.

Special Instructions

In diseases leading to bile outflow disorder parenteral administration is recommended. In hemophilia and Verlhof disease the drug is ineffective.

Limits the effects of indirect anticoagulants.

Fitonadion is preferred over sodium bisulfite menadione for the prevention of hemorrhagic disease in newborns because it is less likely to cause hyperbilirubinemia and hemolytic anemia in newborns (including premature babies).

Impact on driving and operating machinery

When treating with the drug, one should refrain from driving and engaging in other potentially dangerous activities requiring increased concentration and quick psychomotor reactions.

Contraindications

With caution:-6-phosphate dehydrogenase deficiency, hepatic insufficiency.

Side effects

Overdose

Rarely – hypervitaminosis K, manifested by hyperprothrombin and hyperthrombinemia, hyperbilirubinemia, increased blood clotting, thromboembolism. Treatment is symptomatic.
