Pharmacological action
Pharmacodynamics
Antitumor drug from the group of vinca alkaloids (pink vinca alkaloid obtained semisynthetically). The drug blocks cell mitosis at the stage of G2-M metaphase, causing cell death during interphase or subsequent mitosis. At the molecular level, it affects the dynamic equilibrium of tubulin in the cell microtubule apparatus. Navelbin inhibits tubulin polymerization by binding primarily to mitotic microtubules, and at higher concentrations it also affects axonal microtubules. Induction of tubulin spiralization under the influence of Navelbin is less pronounced than with vincristine.
Pharmacokinetics
Absorption and distribution of
After oral administration, it is rapidly absorbed from the digestive tract. Cmax of vinorelbine is achieved after 1.5-3 hours. The absolute bioavailability is on average 40%. Eating does not affect the degree of absorption.
After iv administration, the kinetics of vinorelbine is a three-phase exponential process.
Plasma protein binding is 13.5%. Intensively binds to blood cells and especially to platelets (78%). It penetrates well into tissues and lingers in them for a long time. High concentrations of vinorelbine are determined in the spleen, liver, kidneys, lungs, and thymus gland, moderate in the heart and muscles, and minimal in adipose tissue and bone marrow. The concentration in the lungs is 300 times the concentration in the plasma. It does not penetrate the BBB.
Metabolism and excretion of
Biotransformed in the liver, mainly under the influence of the isoenzyme CYP3A4 with the formation of a number of metabolites, the main one that is detected in the blood is diacetylvinorelbin, which retains antitumor activity. It is excreted mainly with bile. The average T1 / 2 in the terminal phase is 40 hours (27.7-43.6 hours).
Pharmacokinetics in special clinical cases
Pharmacokinetic parameters of Navelbin (administered at a dose of 20 mg / m2 weekly) do not depend on the age of the patients and do not change in moderate or severe liver failure.
Indications
Non-small cell lung cancer
breast cancer
prostate cancer resistant to hormone therapy (in combination with small doses of corticosteroids for oral administration).
Contraindications
Neutrophil count less than 1,500 / μl
platelet count less than 75,000 / μl (for iv administration) and less than 100,000 / μl (for oral administration)
severe infections during the start of therapy or transferred during the last two weeks
marked liver failure, not associated with the tumor process
need for continuous oxygen therapy in patients with lung tumor
diseases and conditions leading to decreased absorption from the gastrointestinal tract (for oral administration)
pregnancy sr dlkp lactation (breastfeeding)
hypersensitivity to the drug and to other vinca alkaloids.
With caution: prescribe the drug for respiratory failure, inhibition of bone marrow hematopoiesis (including after previous chemo- or radiation therapy), constipation or history of intestinal obstruction in history, neuropathy in history.
Use during pregnancy and lactation
Navelbin is contraindicated in pregnancy and lactation (breastfeeding).
Composition
1 capsule contains:
Active substances: vinorelbine tartrate 41.55 mg, which corresponds to the content of vinorelbine 30 mg.
Excipients: anhydrous ethanol - 7.5 mg, purified water - 18.75 mg, glycerol - 3 mg, macrogol 400 - qs up to 262.5 mg.
Capsule shell composition: gelatin, glycerol 85%, anidrisorb 85/70 (D-sorbitol, 1,4-sorbitan, mannitol, higher polyols), medium chain triglycerides PHOSAL 53 MST (phosphatidylcholine, glycerides, ethanol), red iron oxide (E172 ), titanium dioxide (E171).
Dosage and administration of
Navelbin is used both as monotherapy and in combination with other antitumor drugs. When choosing a dose and mode of administration in each individual case, you should consult the specialized literature.
Navelbin Concentrate is administered strictly iv in the form of a 6-10 minute infusion.
Capsules are taken orally as a whole, washed down with water without chewing or dissolving them in the mouth.
In monotherapy mode, the usual dose of the drug for iv administration is 25-30 mg / m2 of the body surface once a week. Navelbin is diluted in 0.9% sodium chloride solution or 5% dextrose solution to a concentration of 1.0-2.0 mg / ml (an average of 50 ml). After administration of the drug, the vein should be flushed, introducing an additional at least 250 ml of 0.9% sodium chloride solution or 5% dextrose solution.
For patients with a body surface area of 2 m2 or more, a single dose of Navelbin for iv administration should not exceed 60 mg.
The recommended single dose of Navelbin for oral administration is 60 mg / m2 of body surface once a week. After the third dose, it is recommended to increase the dose to 80 mg / m2.
An increase in the dose from 60 mg / m2 to 80 mg / m2 can be achieved if, during three weeks of taking Navelbin, grade 4 neutropenia (less than 500 / μl) is observed, or there is one episode of grade 3 neutropenia (less than 1000 / μl, but more than 500 / μl), and the number of neutrophils before the next dose is not lower than 1500 / μl.

For patients with a BSA of 2 m2 or more, the total single dose of Navelbin for oral administration should never exceed 120 mg per week when prescribing the drug at a dose of 60 mg / m2 and 160 mg per week at a dose of 80 mg / m2.
The use of Navelbin orally in doses of 60 mg / m2 and 80 mg / m2 corresponds to the iv administration of Navelbin in doses of 25 mg / m2 and 30 mg / m2.
With polychemotherapy, the dose and frequency of administration of Navelbin (both with iv and oral administration) depend on the specific antitumor therapy program.
With a decrease in the number of neutrophils less than 1,500 / μl or platelets less than 75,000 / μl (with iv) or less than 100,000 / μl (when taken orally), the next administration or intake of Navelbin is postponed for 1 week. If due to hematological toxicity it was necessary to refrain from 3 weekly injections or doses of the drug, it is recommended to discontinue the use of Navelbin.
Patients with severe hepatic insufficiency, Navelbin should be prescribed with caution, in a dose reduced by 33%.
Safety and efficacy of Navelbine in children have not been studied.
Special correction of the dosage regimen of Navelbin in the elderly is not required.
Side effects
The following are side effects according to the WHO classification: From the hemopoietic system: very rarely - leukopenia, thrombocytopenia.
From the digestive system: often - abdominal pain, diarrhea, constipation, flatulence infrequently - nausea, vomiting rarely - dry mouth is very rare - increased activity of hepatic transaminases and gamma-glutamintransferase (GGT), severe liver damage leading to jaundice with liver failure or without.
On the part of the immune system: very rarely - anaphylactic reactions, including anaphylactic shock.
From the musculoskeletal system: re
Drug Interaction
When used together with other cytostatics, mutual aggravation of side effects is possible, first of all - myelosuppression.
When combined with mitomycin C, acute respiratory failure may develop.
When used with paclitaxel increases the risk of neurotoxicity.
Radiation therapy results in radiosensitization. The use of Navelbin after radiation therapy can lead to the re-emergence of radiation reactions.
Concurrent administration of the drug with inducers and inhibitors of cytochrome P450 isoenzymes can lead to changes in the pharmacokinetics of vinorelbine.
Overdose
Symptoms: suppression of bone marrow function, neurotoxic reactions.
Treatment: in case of overdose, the patient should be hospitalized and symptomatic therapy should be carried out with careful monitoring of vital organ functions. The specific antidote is unknown.
Storage conditions
Keep out of the reach of children at temperatures from 2 ° to 8 ° C.
The Expiration of
is 2.5 years.
