Interaction

Cisplatin reduces the total clearance of paclitaxel by 20%, so when combined chemotherapy paclitaxel should be administered before cisplatin. More pronounced myelosuppression is observed when paclitaxel is administered after cisplatin. With combined chemotherapy (paclitaxel and cisplatin), the risk of developing renal failure is higher than with cisplatin monotherapy.

Concomitant use with cimetidine, ranitidine, dexamethasone or diphenhydramine does not affect the binding of paclitaxel to plasma proteins.

Since elimination of doxorubicin and its active metabolites can be reduced by shortening the time interval between paclitaxel and doxorubicin use, paclitaxel should be administered 24 hours after doxorubicin.

Information on the potential interaction of paclitaxel with inhibitors and inducers of cytochrome P450 isoenzymes (in particular, the CYP3A4 isoenzyme) is limited, so caution should be exercised when using inhibitors (for example, erythromycin, fluoxetine, gemfibrozil) or inducers (for example, rifampicin, carbamazepine, phenytoin, phenobarbital) of cytochrome P450 isoenzymes at the same time.

Microsomal oxidation inhibitors (including ketoconazole, cimetidine, verapamil, diazepam, quinidine, cyclosporine) inhibit paclitaxel metabolism. However, it is known that with simultaneous use of ketoconazole and paclitaxel, the elimination of the latter does not slow down, so both drugs can be used without dose adjustment.

Concomitant use of paclitaxel with nelfinavir or ritonavir (but not indinavir) significantly reduces the systemic clearance of paclitaxel. There is insufficient information on the interaction of paclitaxel and other protease inhibitors when used concomitantly.

Polyoxyethylated castor oil, which is part of paclitaxel, can cause the extraction of di-(2-hexyl)phthalate (DEHP) from plasticized PVC containers, and the degree of leaching of DEHP increases with increasing solution concentration and time. Therefore, when preparing, storing and administering Paclitaxel-Ebeve, you should use equipment that does not contain PVC parts.

How to take, course of use and dosage

Enter iv.

Paclitaxel can be used both as monotherapy and in combination with other antitumor drugs. The dose and regimen of the drug are selected individually.

To prevent severe hypersensitivity reactions, all patients should be premedicated using corticosteroids, histamine H1 – and H2-receptor blockers. The recommended premedication regimen is 20 mg dexamethasone (or its equivalent) orally approximately 12 hours and 6 hours before use of Paclitaxel-Ebeve,50 mg diphenhydramine (or its equivalent) IV and 300 mg cimetidine or 50 mg ranitidine IV 30-60 minutes before use of Paclitaxel-Ebeve.

First-line chemotherapy for ovarian cancer

A combined treatment regimen with paclitaxel and cisplatin is recommended. Paclitaxel is administered at a dose of 175 mg / m2 of body surface area for a 3-hour intravenous infusion or at a dose of 135 mg/m2 for a 24-hour intravenous infusion, followed by cisplatin at a dose of 75 mg/m2. The intervals between courses are 3 weeks.

Second-line chemotherapy for ovarian cancer

Paclitaxel is recommended to be administered at a dose of 175 mg / m2 of body surface area by 3-hour intravenous infusion. The intervals between courses are 3 weeks.

Adjuvant chemotherapy for breast cancer

Paclitaxel is prescribed after chemotherapy with anthracyclines and cyclophosphamide. Paclitaxel is recommended to be administered at a dose of 175 mg/m2 IV for 3 h. 4 courses with intervals between courses-3 weeks.

First-line chemotherapy for breast cancer

In the case of combined use with doxorubicin (at a dose of 50 mg/m2 of body surface area), paclitaxel should be administered 24 hours after doxorubicin.

The recommended dose of paclitaxel is 220 mg / m2 of body surface area when administered by a 3-hour intravenous infusion. The intervals between courses are 3 weeks.

In the case of combined use with trastuzumab, paclitaxel is recommended to be administered at a dose of 175 mg/m2 of body surface area by 3-hour intravenous infusion with an interval between courses of 3 weeks.Paclitaxel can be administered the day after the first dose of trastuzumab or immediately after subsequent doses, if the previous doses of trastuzumab were well tolerated.

Second-line chemotherapy for breast cancer

Paclitaxel is recommended to be administered at a dose of 175 mg / m2 by 3-hour intravenous infusion. The intervals between courses are 3 weeks.

Chemotherapy for advanced non-small cell lung cancer

A combined treatment regimen with paclitaxel and cisplatin is recommended. Paclitaxel is administered at a dose of 175 mg / m2 of body surface area by a 3-hour intravenous infusion, followed by cisplatin at a dose of 80 mg/m2. The intervals between courses are 3 weeks.

Chemotherapy for Kaposi’s sarcoma on the background of AIDS

Paclitaxel is recommended to be administered at a dose of 100 mg / m2 by 3-hour intravenous infusions. The intervals between courses are 2 weeks.

Subsequent doses of paclitaxel are set individually depending on the tolerability of therapy. The next dose of paclitaxel can be administered only after increasing the number of neutrophils to ≥1500 cells/µl (≥1000 cells/µl in the case of Kaposi’s sarcoma), and platelets to > 100,000 cells/mm3 (>> 75,000 cells/mm3 in the case of Kaposi’s sarcoma). Patients who have experienced severe neutropenia (neutrophil count less than 500 cells/µl for 7 days or more) or severe peripheral neuropathy, the following doses are reduced by 20% (25% in the case of Kaposi’s sarcoma).

Currently, there is insufficient data to provide recommendations for dose adjustment in patients with mild or moderate hepatic impairment. Patients with severe hepatic impairment should not be prescribed paclitaxel.

Rules for preparing the solution for infusions

When preparing, storing, and administering Paclitaxel-Ebeve, use equipment that does not contain PVC, such as glass, polypropylene, or polyolefin.

The drug solution is prepared by diluting the concentrate to the final concentration of paclitaxel from 0.3 to 1.2 mg / ml. As a diluent solution can be used: 0.9% sodium chloride solution,5% dextrose solution,5% dextrose solution in 0.9% sodium chloride solution,5% dextrose solution in Ringer’s solution. The prepared solutions may opalescent due to the carrier base present in the dosage form. When the drug is administered, a system with a membrane filter (pore size not exceeding 0.22 microns) should be used.

Infusion solutions prepared by diluting Paclitaxel-Ebeve with 0.9% sodium chloride solution or 5% dextrose solution are physically and chemically stable for 51 hours when stored at 25°C and 14 days when stored at 5°C. From a microbiological point of view, the infusion solution should be administered immediately after preparation. If the solution is not used immediately after preparation, the storage time should not exceed 24 hours at a temperature of 2° to 8°C, unless the solution was prepared under controlled aseptic conditions.

To reduce the risk of sediment formation, the infusion solution should be administered immediately after dilution and avoid excessive shaking, vibration and agitation.

The infusion system should be thoroughly flushed before use. During use, it is necessary to regularly monitor the appearance of the solution and stop the infusion if a sediment is detected.

Overdose

Symptoms: bone marrow suppression, peripheral neuropathy, inflammation and ulceration of the mucous membranes.

Treatment: symptomatic. The antidote to paclitaxel is not known.

Special instructions

The use of Paclitaxel-Ebeve should be carried out under the supervision of a doctor who has experience with antitumor chemotherapeutic drugs.

If severe hypersensitivity reactions develop, Paclitaxel-Ebeve should be discontinued immediately and symptomatic therapy should be initiated, and repeated use of the drug should not be carried out.

If Paclitaxel-Ebeve is used in combination with cisplatin, Paclitaxel-Ebeve should be administered first, followed by cisplatin.

When working with Paclitaxel-Ebeve, care should be taken (as when working with other cytotoxic substances), wear gloves and avoid contact with the skin or mucous membranes. In case of contact with the skin, it should be thoroughly washed with soap and water; in case of contact with the eyes – with plenty of water.

Monitoring of laboratory parameters

During treatment, it is necessary to regularly monitor the picture of peripheral blood, blood pressure, heart rate and the number of breaths (especially during the first hour of infusion).

ECG monitoring should be performed before starting therapy and regularly during treatment.

If AV conduction disorders develop during repeated injections, continuous ECG monitoring should be performed.

Use in pediatrics

The safety and efficacy of Paclitaxel-Ebeve in children has not been established. Use in pediatrics is contraindicated.

Influence on the ability to drive vehicles and other mechanisms that require increased concentration of attention

Due to the likelihood of side effects, such as headache, dizziness, drowsiness, during treatment, patients should refrain from engaging in potentially dangerous activities that require increased concentration of attention and speed of psychomotor reactions.

Precautions for handling and disposal of unused product

Caution should be exercised when using Paclitaxel-Ebeve. Dilute the drug should be in aseptic conditions in a specially designated room. This should be handled by trained personnel. It is necessary to take all measures to prevent the paclitaxel solution from getting on the skin and mucous membranes, in particular, use protective clothing (robe, cap, mask, glasses and disposable gloves). Shortness of breath, chest pain, burning sensation in the throat, and nausea have been reported when inhaling paclitaxel vapors or sprayed solutions.

If paclitaxel gets on the skin or mucous membranes, wash thoroughly with soap and water or (eyes) with plenty of water.

The drug should not be frozen, as it can form a precipitate. This precipitate usually dissolves when the vial is heated to room temperature (25°C). If the solution in the previously frozen bottle remains cloudy or there is an insoluble precipitate, the drug cannot be used and such a bottle must be destroyed. The prepared infusion solution does not need to be protected from light.

Drug residues and all tools and materials that were used to prepare the solution for infusion and use of Paclitaxel-Ebeve should be disposed of in accordance with the standard hospital procedure for the disposal of cytotoxic substance waste, taking into account the current regulations for the disposal of hazardous waste.
