Taxotere® Preparation

Formulation

Taxotere® (docetaxel) is formulated as a concentrate for dilution. It is a clear-yellow to brownish-yellow viscous solution. Each milliliter contains 40 mg docetaxel (anhydrous) and 1040 mg polysorbate 80. The diluent for Taxotere® is 13% ethanol in water for injection.1

Steps for preparation of Taxotere
Please note the following important information about Taxotere® preparation:

  • Taxotere® requires two dilutions prior to administration.
  • Each vial is a single-dose vial and should not be used for multiple doses.
  • The initial diluted solution may be used immediately or stored either in the refrigerator or at room temperature for a maximum of 8 hours.
  • Taxotere® initial diluted solution should be visually inspected prior to use. Solutions containing any precipitate or particulate matter must not be used.
  • Infusion solution should be used within 4 hours.1

First dilution: Preparation of Taxotere® initial diluted solution1

1.  It is not necessary to store Taxotere® under refrigeration; however, if Taxotere® is stored in the refrigerator, the Taxotere® and diluent vials should stand at room temperature for at least 5 minutes before preparation.
2.  Aseptically withdraw the entire contents of the diluent vial by partially inverting the vial and inserting the needle through the diaphragm at an angle. Place the needle — bevel side down — against the glass, with the tip touching the neck of the vial. Pull back the plunger and extract all the solution. This is necessary to ensure the initial diluted solution of 10 mg/mL.

NOTE: Both the Taxotere® Injection Concentrate and the diluent vials contain an overfill to compensate for liquid loss during preparation. This overfill ensures that after dilution with entire contents (approximately 1.8 mL for Taxotere® 20 mg and approximately 7.1 mL for Taxotere® 80 mg) of the accompanying diluent, there is an initial diluted solution containing 10 mg/mL docetaxel.

3.  Insert the needle at an angle into the Taxotere® vial. Inject all of the diluent along the side of the vial to reduce foaming. Be careful not to scratch the glass wall with the needle.
4.  Mix the initial diluted solution by repeated inversions for at least 45 seconds to assure full mixture of the concentrate and diluent. To minimize foaming, DO NOT SHAKE.
5.  Allow the premix vial to stand for 5 minutes at room temperature and then check that the solution is homogeneous and clear (foaming is normal even after 5 minutes due to the presence of polysorbate 80 in the formulation). Solutions containing any precipitate or particulate matter must not be used. The initial diluted Taxotere® solution contains 10 mg docetaxel/mL and may be used immediately or stored either in the refrigerator or at room temperature for a maximum of 8 hours.

Second dilution: Final dilution for infusion solution1

1.  Aseptically withdraw the required amount of Taxotere® initial diluted solution (10 mg/mL) with a calibrated syringe.
2.  Inject the required amount of Taxotere® into the appropriate (non-PVC) infusion bag or bottle of either 0.9% sodium chloride or 5% dextrose solution. The final concentration should be between 0.3 and 0.74 mg/mL.
3.  Thoroughly mix the infusion solution by manual rotation.
4.  Inspect Taxotere® visually for particulate matter or discoloration. Solutions containing any precipitate or particulate matter must not be used, and should be discarded. Any unused Taxotere® should also be discarded.
