Full Prescribing Info
Dosage/Direction for Use
All patients should be premedicated before paclitaxel is administered to prevent severe hypersensitivity reactions (see Precautions).
Before every treatment cycle, patients should be premedicated with: dexamethasone 20 mg orally 12 hours and 6 hours prior to starting the paclitaxel infusion.
promethazine 25 mg to 50 mg intravenously or other suitable H1-antagonist, 30 minutes prior to starting the paclitaxel infusion.
cimetidine 300 mg or ranitidine 50 mg by intravenous infusion over 15 minutes, starting 30 minutes prior to the paclitaxel infusion.
For primary treatment of ovarian cancer, it is recommended that paclitaxel be used at a dose of: 175 mg/m2, administered intravenously over 3 hours, followed by cisplatin 75 mg/m2. The infusion should be repeated every three weeks.
135 mg/m2, administered intravenously over 24 hours, followed by cisplatin 75 mg/m2. The infusion should be repeated every three weeks.
For the treatment of metastatic ovarian cancer or metastatic breast cancer, it is recommended that paclitaxel be used as a single agent at a dose of 175 mg/m2. Paclitaxel should be administered as an intravenous infusion over 3 hours. The infusion should be repeated every 3 weeks as tolerated. Patients have tolerated treatment with up to 9 cycles of paclitaxel therapy, but the optimal course of therapy remains to be established.
For primary or secondary treatment of NSCLC, the recommended dose of paclitaxel is 175 mg/m2 administered intravenously over 3 hours with a 3 week interval between courses.
Repetition of a course of paclitaxel is not recommended until the patient's neutrophil count is at least 1.5 x 109 cells/L (1,500 cells/mm3) and the platelet count is at least 100 x 109 cells/L (100,000 cells/mm3). If there is severe neutropenia (neutrophil count less than 0.5 x 109 cells/L for 7 or more days) or severe peripheral neuropathy during paclitaxel therapy, the dose of paclitaxel in subsequent courses should be reduced by 20% (see Precautions).
Dilution: Anzatax Injection Concentrate MUST BE DILUTED PRIOR TO INTRAVENOUS INFUSION. It should be diluted in 5% glucose or 0.9% sodium chloride intravenous infusion.
Dilution should be made to a final concentration of 0.3 to 1.2 mg/mL.
After the final dilution of Anzatax Injection Concentrate, the bottle should be swirled gently to disperse the paclitaxel. DO NOT SHAKE.
Avoid contact of paclitaxel solutions with plasticised polyvinyl chloride (PVC) equipment, infusion lines or devices used when preparing infusion solutions. Prepare and store diluted paclitaxel solutions in glass bottles or non-PVC infusion bags. These precautions are to avoid leaching of the plasticiser DEHP (di-[2-ethylhexyl] phthalate) from PVC infusion bags or sets. Paclitaxel solutions should be administered through polyethylene lined administration sets (e.g. Gemini 20 giving set), using an IMED pump.
Although solutions of paclitaxel for infusion prepared as outlined above are chemically stable for 3 days at room temperature (25°C) and 14 days at 2°C to 8°C, it is recommended that the solution for infusion should be administered immediately after preparation as it does not contain an antimicrobial agent. The infusion should be completed within 24 hours of preparation of the solution and any residue discarded, according to the guidelines for the disposal of cytotoxic drugs (see Handling and Disposal as follows).
Use in one patient on one occasion only.
Compounding centres which: are licensed by the TGA to reconstitute and/or further dilute cytotoxic products; and have validated aseptic procedure and regular monitoring of aseptic technique may apply the following shelf lives when stored under the specified conditions: (See table.)

Solutions prepared this way have been shown to be chemically stable for these periods. Administration should be completed within 24 hours of the start of the infusion and any residue discarded according to the guidelines for the disposal of cytotoxic drugs. Do not use paclitaxel if any precipitation forms or if the diluted solution appears cloudy.
Filtration: A microporous membrane of 0.22 microns or less in size is recommended as the in-line filter for all infusions of paclitaxel. The IMED 0.2 micron add on filter set composed of polysulfone and the IVEX II 0.2 micron filter composed of cellulose have both been found to be suitable for Anzatax Injection Concentrate.
Handling and disposal: The published guidelines related to procedures for the proper handling and disposal of cytotoxic drugs should be followed.
