Paclitaxel, nanoparticle albumin-bound (Abraxane)
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. The nanoparticle albumin bound characteristic of Abraxane eliminates the need for it to be dissolved in Cremophor EL (polyoxyethylated castor oil) like Paclitaxel (Taxol) and the risk of hypersensitivity infusion reactions related to Cremophor.[1][2][3]
Route: IV
Extravasation: irritant
