Pharmacotherapy Group

Antitumor agent, antimetabolite

Условия хранения

The drug should be stored out of the reach of children, protected from light, at a temperature not exceeding 25 ° C.

Expiration date

Shelf life is 4 years. Do not use after the expiration date indicated on the package.

Pharmacological action

The antitumor effect is due to a violation of the synthesis of DNA and RNA. The fluorouracil formed as a result of hydrolysis inhibits the enzyme thymidylate synthetase and DNA synthesis, is introduced into the structure of RNA instead of uracil, making it defective, and inhibits cell proliferation.

In tumor cells, it is converted to 5-fluorodeoxyuridine-5-monophosphate, which is then phosphorylated into triphosphate and incorporated into RNA, and phloxuridine monophosphate, which inhibits thymidylate synthetase. It is less toxic and better tolerated by patients than 5-fluorouracil.

Показания

colon and rectal cancer;

stomach cancer;

breast cancer;

atopic dermatitis;

cutaneous lymphomas.

Method of application, course and dosage

The drug is taken orally. The daily dose of Fluorafur® is 20-30 mg / kg body weight (1.2-1.6 g) in 2-4 doses, but not more than 2 g / day.

The course dose is 30-40 g. The interval between courses is 4 weeks.

The dose of Fluorafur® can be reduced in elderly patients and at a late stage of the disease.

Overdose

Symptoms: increased toxic effects from the gastrointestinal tract, central nervous system and inhibition of hematopoiesis.

Treatment: control of hematopoiesis function for at least 4 weeks, if necessary, symptomatic therapy is performed. The specific antidote to tegafur is unknown.

Drug interaction

Tegafur increases the effectiveness of other chemotherapeutic agents (oxaliplatin, raltitrexide, cyclophosphamide, methotrexate, doxorubicin, mitomycin) and radiation therapy (possibly increasing the risk of adverse events).

The tolerability of tegafur improves with simultaneous administration of calcium folinate.

When used concomitantly with phenytoin, it enhances the effect of the latter.

Inhibitors of microsomal oxidation in the liver increase the toxicity of tegafur.

Use during pregnancy and lactation

The drug is contraindicated for use during pregnancy and lactation (breastfeeding).

The drug is used with caution in patients with impaired hematopoiesis, impaired liver and kidney function of mild to moderate degree, as well as impaired glucose metabolism.

Special instructions

The blood count and the functional state of the liver and kidneys should be monitored regularly.

With prolonged use of the drug, its side effect increases.

It should be borne in mind that the drug inhibits the reproductive function of the patient.

Dizziness, nausea, and vomiting decrease when the daily dose is divided into several doses.

The effect on hematopoiesis may occur 8-14 days after the end of treatment.

During treatment, careful oral care is necessary.
