Hướng dẫn pha thuốc
Add 1 mL of diluent to a 20 mg vial to provide a soln containing 20 mg/0.8 mL or 4 mL of diluent to 80 mg vial to provide a soln containing 24 mg/mL of the drug. Shake well to ensure complete dissolution of the drug. The required amount of reconstituted soln should be injected into a 250-mL infusion bag or bottle containing NaCl 0.9% inj or dextrose 5% inj to produce a final soln of 0.3-0.74 mg/mL. For doses >200 mg, the vol of IV soln should be increased accordingly so that the concentration does not exceed 0.74 mg/mL.
Y-site: Amphotericin B, doxorubicin liposome, methylprednisolone Na succinate, nalbuphine.

CYP3A4 inducers, inhibitors, or substrates may alter docetaxel metabolism.
Description: Docetaxel promotes the assembly of microtubules from tubulin dimers, and inhibits the depolymerisation of tubulin which stabilizes microtubules in the cell. This results in inhibition of DNA, RNA, and protein synthesis. Most activity occurs during the M phase of the cell cycle. Pharmacokinetics: Distribution: Rapidly distributed to body tissues. Plasma protein binding: >95%. Metabolism: Extensively hepatic, by CYP3A4 isoenzyme. Excretion: Mainly via faeces (as metabolites); via urine (approx 6%). Terminal elimination half-life: Approx 11 hr.
