Nanoparticle albumin-bound paclitaxel, commonly known as nab paclitaxel, is a formulation of the chemotherapy drug paclitaxel that uses albumin nanoparticles to improve delivery and efficacy. Paclitaxel is a well-known chemotherapeutic agent used in the treatment of various cancers, including breast cancer, lung cancer, and pancreatic cancer. The innovation in nab paclitaxel lies in its delivery system, which enhances the drug's solubility and reduces the need for toxic solvents.
