Paclitaxel is a tubulin inhibitor. It was originally identified and isolated from the bark of the Pacific yew, Taxus brevifolia (hence the name 'taxol', and naming of the taxane family of compounds- includes docetaxel and cabazitaxel). The drug can be administered as a solvent-based drug, or in a formulation called nab-paclitaxel. Nab-paclitaxel consists of paclitaxel bound to albumin nanoparticles as a delivery vehicle (trade name Abraxane)- nab stands for nanoparticle albumin-bound.
