General information

Class/mechanism: Taxane, promotes assembly of microtubules, stablizes microtubules, preventing depolymerization. Paclitaxel interferes with the normal dynamic reorganization of microtubules that is necessary for regular interphase/mitosis processes. It also leads to creation of abnormal bundles of microtubules. Paclitaxel is highly lipophilic/insoluble in water and needs to be dissolved in Cremophor EL (polyoxyethylated castor oil), which may cause hypersensitivity infusion reactions.^[1]^[2]
Route: IV
Extravasation: irritant (usually), vesicant (rare)

For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.^[1]

History of changes in FDA indication

12/29/1992: Initial FDA approval (label is not available)
4/9/1998 (earliest label available on Drugs @ FDA): Indicated for:

First-line and subsequent therapy for the treatment of advanced carcinoma of the ovary. As first-line therapy, Taxol is indicated in combination with cisplatin.
The treatment of breast cancer after failure of combination therapy for metastatic disease or relapsed within 6 months of adjuvant chemotherapy. Prior therapy should have included an anthracycline unless clinically contraindicated.
The second-line treatment of AIDS-related Kaposi's sarcoma.

6/30/1998: New indication added: in combination with cisplatin, is indicated for the first-line treatment of non-small cell lung cancer in patients who are not candidates for potentially curative surgery and/or radiation therapy.
10/25/1999: New indication for the adjuvant treatment of node-positive breast cancer administered sequentially to standard doxorubicin-containing combination chemotherapy.
