The eribulin drug is a non-taxane microtubule dynamics inhibitor indicated for patients in the UK and USA with metastatic breast cancer who have received prior chemotherapeutic regimens. Mechanistically, this eribulin mesylate injection functions as a molecular "scaffolding anchor." By binding specifically to the growing ends of microtubules, the eribulin drug prevents the cellular framework from extending, which triggers an irreversible mitotic blockade and subsequent cell death (MHRA, 2023; FDA, 2022). Unlike taxanes, it uniquely spares the microtubule shortening phase.
