Docetaxel is an antineoplastic agent belonging to the taxoid family. It is prepared by semisynthesis beginning with a precursor extracted from the renewable needle biomass of yew plants. The chemical name for docetaxel is (2R,3S)-N-carboxy-3-phenylisoserine,N-tert-butyl ester, 13-ester with 5β-20-epoxy-1,2α,4,7β,10β,13α-hexahydroxytax-11-en-9-one 4-acetate 2-benzoate. Docetaxel (anhydrous) has the following structural formula:
Docetaxel is a white to almost-white powder with an empirical formula of C43H53NO14, and a molecular weight of 807.88. It is highly lipophilic and practically insoluble in water.
Docetaxel Injection, USP is a sterile, non-pyrogenic, clear, colorless to pale yellow solution at 10 mg/mL concentration.
Each mL contains 10 mg docetaxel (anhydrous), 260 mg polysorbate 80 NF, 4 mg anhydrous citric acid USP, 23% v/v dehydrated alcohol USP, and polyethylene glycol 300 NF.
Docetaxel Injection is available in single-dose vials containing 20 mg (2 mL) docetaxel (anhydrous), and multiple-dose vials containing 80 mg (8 mL) or 160 mg (16 mL) docetaxel (anhydrous).
Docetaxel Injection requires NO prior dilution with a diluent and is ready to add to the infusion solution.
