Microtubule inhibitors are used to treat various types of cancer, including breast cancer, non-small cell lung cancer, ovarian cancer, and more. These medications work by disrupting the microtubules in cancer cells, which are essential for cell division, thereby stopping the cancer cells from multiplying. Microtubule inhibitors often come as injectable solutions. Examples include paclitaxel (Abraxane), docetaxel (Taxotere), and eribulin (Halaven).
