英文版说明书:

BiCNU®(carmustine for injection)RECONSTITUTION / DILUTIONStabilityOnly use glass or polyolefin containers for BiCNU administration.Stability:The unopened vial of the dry drug must be stored in a refrigerator (2°-8°C, 36°-46°F). The diluent ampules may be stored at controlled room temperature (59°-86°F, 15°-30°C) or in a refrigerator (2°-8°C, 36°-46°F). The recommended storage of unopened BiCNU vials provides a stable product for up to 3 years. After reconstitution as recommended, BiCNU is stable for 24 hours under refrigeration (2°-8°C, 36°-46°F). Reconstituted vials should be examined for crystal formation prior to use. If crystals are observed, they may be redissolved by warming the vial to room temperature with agitation.Vials reconstituted as directed and further diluted to a concentration of 0.2 mg/mL in 5% Dextrose Injection, USP, should be stored at room temperature, protected from light and utilized within 8 hours.Dilution examples:[Dose < 20mg] [100ml ] [1 -2 hours][Dose 20 – 50mg] [250 ml ] [1 -2 hours][Dose > 50 mg] [500ml ] [1 -2 hours]Reconstitution:First, dissolve BiCNU with 3 mL of the supplied sterile diluent (Dehydrated Alcohol Injection, USP). Second, aseptically add 27 mL Sterile Water for Injection, USP. Each mL of resulting solution contains 3.3 mg of BiCNU in 10% ethanol. Such solutions should be protected from light.Administration:The reconstituted solution should be used intravenously only and should be administered by IV drip. Injection of BiCNU over shorter periods of time than 1 to hours may produce intense pain and burning at the site of injection.Infusion through a free-flowing saline or dextrose infusion, or administration through a central catheter can alleviate venous pain/irritation.High-dose carmustine: Maximum rate of infusion of leq3 mg/m2/minute to avoid excessive flushing, agitation, and hypotension; infusions should run over at least hours; some investigational protocols dictate shorter infusions. (High-dose carmustine is fatal if not followed by bone marrow or peripheral stem cell infusions)Note: double mouse click to return to the top of the pageWARNINGSBiCNU (carmustine for injection) should be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents.Bone marrow suppression, notably thrombocytopenia and leukopenia, which may contribute to bleeding and overwhelming infections in an already compromised patient, is the most common and severe of the toxic effects of BiCNU (see PACKAGE INSERT FOR WARNINGS and ADVERSE REACTIONS).Since the major toxicity is delayed bone marrow suppression, blood counts should be monitored weekly for at least 6 weeks after a dose (see PACKAGE INSERT FOR ADVERSE REACTIONS). At the recommended dosage, courses of BiCNU should not be given more frequently than every 6 weeks.The bone marrow toxicity of BiCNU is cumulative and therefore dosage adjustment must be considered on the basis of nadir blood counts from prior dose (see “Dosage Adjustment Table” under DOSAGE AND ADMINISTRATION).Pulmonary toxicity from BiCNU appears to be dose related. Patients receiving greater than 1400 mg/m2 cumulative dose are at significantly higher risk than those receiving less.Delayed pulmonary toxicity can occur years after treatment, and can result in death, particularly in patients treated in childhood (see PACKAGE INSERT FOR ADVERSE REACTIONS and PRECAUTIONS: Pediatric Use).CLINICAL PHARMACOLOGYAlthough it is generally agreed that carmustine alkylates DNA and RNA, it is not cross-resistant with other alkylators. As with other nitrosoureas, it may also inhibit several key enzymatic processes by carbamoylation of amino acids in proteins.Intravenously administered carmustine is rapidly degraded, with no intact drug detectable after 15 minutes. However, in studies with 14C-labeled drug, prolonged levels of the isotope were detected in the plasma and tissue, probably representing radioactive fragments of the parent compound.Itis thought that the antineoplastic and toxic activities of carmustine may be due to metabolites. Approximately 60% to 70% of a total dose is excreted in the urine in 96 hours and about 10% as respiratory CO2. The fate of the remainder is undetermined.Because of the high lipid solubility and the relative lack of ionization at physiological pH, carmustine crosses the blood-brain barrier quite effectively. Levels of radioactivity in the CSF are greater than or equal50% of those measured concurrently in plasma.INDICATIONS AND USAGEBiCNU is indicated as palliative therapy as a single agent or in established combination therapy with other approved chemotherapeutic agents in the following:1.Brain tumors—glioblastoma, brainstem glioma, medulloblastoma, astrocytoma, ependymoma, and metastatic brain tumors.2.Multiple myeloma—in combination with prednisone.3.Hodgkin’s Disease—as secondary therapy in combination with other approved drugs in patients who relapse while being treated with primary therapy, or who fail to respond to primary therapy.4.Non-Hodgkin’s lymphomas—as secondary therapy in combination with other approved drugs for patients who relapse while being treated with primary therapy, or who fail to respond to primary therapy.CONTRAINDICATIONSBiCNU should not be given to individuals who have demonstrated a previous hypersensitivity to it.DOSAGE AND ADMINISTRATIONThe recommended dose of BiCNU as a single agent in previously untreated patients is 150 to 200 mg/m2 intravenously every 6 weeks. This may be given as a single dose or divided into daily injections such as 75 to 100 mg/m2 on 2 successive days. When BiCNU is used in combination with other myelosuppressive drugs or in patients in whom bone marrow reserve is depleted, the doses should be adjusted accordingly.Doses subsequent to the initial dose should be adjusted according to the hematologic response of the patient to the preceding dose.The following schedule is suggested as a guide to dosage adjustment:Nadir AfterPrior Dose Percentage of Prior Dose tobe GivenLeukocytes/mm3 Platelets/mm3>4000 >100,000 100%3000–3999 75,000–99,999 100%2000–2999 25,000–74,999 70%<2000 <25,000 50%A repeat course of BiCNU should not be given until circulating blood elements have returned to acceptable levels (platelets above 100,000/mm3, leukocytes above 4,000/mm3), and this is usually in 6 weeks. Adequate number of neutrophils should be present on a peripheral blood smear. Blood counts should be monitored weekly and repeat courses should not be given before 6 weeks because the hematologic toxicity is delayed and cumulative.Administration PrecautionsAs withother potentially toxic compounds, caution should be exercised in handling BiCNU and preparing the solution of BiCNU. Accidental contact of reconstituted BiCNU with the skin has caused transient hyperpigmentation of the affected areas. The use of gloves is recommended. If BiCNU lyophilized material or solution contacts the skin or mucosa, immediately wash the skin or mucosa thoroughly with soap and water.The reconstituted solution should be used intravenously only and should be administered by IV drip. Injection of BiCNU over shorter periods of time than 1 to 2 hours may produce intense pain and burning at the site of injection.Preparation of Intravenous SolutionsFirst, dissolve BiCNU with 3 mL of the supplied sterile diluent (Dehydrated Alcohol Injection, USP). Second, aseptically add 27 mL Sterile Water for Injection, USP. Each mL of resulting solution contains 3.3 mg of BiCNU in 10% ethanol. Such solutions should be protected from light.Reconstitution as recommended results in a clear, colorless to yellowish solution which may be further diluted with 5% Dextrose Injection, USP. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.Important NoteThe lyophilized dosage formulation contains no preservatives and is not intended for use as a multiple dose vial.StabilityThe unopened vial of the dry drug must be stored in a refrigerator (2°-8°C, 36°-46°F). The diluent ampules may be stored at controlled room temperature (59°-86°F, 15°-30°C) or in a refrigerator (2°-8°C, 36°-46°F). The recommended storage of unopened BiCNU vials provides a stable product for up to 3 years. After reconstitution as recommended, BiCNU is stable for 24 hours under refrigeration (2°-8°C, 36°-46°F). Reconstituted vials should be examined for crystal formation prior to use. If crystals are observed, they may be redissolved by warming the vial to room temperature with agitation.Vials reconstituted as directed and further diluted to a concentration of 0.2 mg/mL in 5% Dextrose Injection, USP, should be stored at room temperature, protected from light and utilized within 8 hours.Glass containers were used for the stability data provided in this section.Only use glass containers for BiCNU administration.Important NoteBiCNU has a low melting point (30.5°-32.0°C or 86.9°-89.6°F). Exposure of the drug to this temperature or above will cause the drug to liquefy and appear as an oil film on the vials. This is a sign of decomposition and vials should be discarded. If there is a question of adequate refrigeration upon receipt of this product, immediately inspect the vial in each individual carton. Hold the vial to a bright light for inspection. The BiCNU will appear as a very small amount of dry flakes or dry congealed mass. If this is evident, the BiCNU is suitable for use and should be refrigerated immediately.Procedures for proper handling and disposal of anticancer drugs should be considered. Several guidelines on this subject have been published.1-8 There is no general agreement that all of the procedures recommended in the guidelines are necessary or appropriate.To minimize the risk of dermal exposure, always wear impervious gloves when handling vials containing BiCNU. This includes all handling activities in clinical settings, pharmacies, storerooms, and home healthcare settings, including during unpacking and inspection, transport within a facility, and dose preparation and administration.HOW SUPPLIEDBiCNU® (carmustine for injection). Each package includes a vial containing 100 mg carmustine and an ampule containing 3 mL sterile diluent.NDC 0015-3012-60STORAGEStore in a refrigerator (2°-8°C, 36°-46°F).
