Nab-paclitaxelinfo-icon (Abraxaneinfo-icon) is a taxaneinfo-icon-type chemotherapyinfo-icon medicineinfo-icon used to treat breast cancer. It is paclitaxel (Taxolinfo-icon) wrapped in the proteininfo-icon albumin. The albumin allows the medicine to be given in water. This lessens the risk of an allergic reaction, which is common with taxanes like paclitaxel or docetaxelinfo-icon.

Taxanes must be put in a solvent, a sort of wrapper, so they can dissolve in your body. Some of the side effects of paclitaxel are associated with its wrapper rather than with the medicine itself. So, a different type of paclitaxel, wrapped in protein, was developed. This medicine is called nanoparticle albumin bound-paclitaxel, or nab-paclitaxel.  Like paclitaxel, nab-paclitaxel can be used to treat all stages of breast cancer.

Other names for this medicine include ABI-007, nanoparticle albumin-bound paclitaxel, paclitaxel albumin-stabilized nanoparticle formulationinfo-icon, and protein-bound paclitaxelinfo-icon.
