Used primarily as an anticancer agent, especially in the treatment of ovarian, breast, and lung cancers. It works by stabilizing microtubules, preventing their disassembly, which stops cell division and induces apoptosis in rapidly dividing tumor cells. Also used in the treatment of Kaposi's sarcoma and other solid tumors. Employed in drug-eluting stents to prevent restenosis by inhibiting smooth muscle cell proliferation. Its mechanism makes it valuable in combination therapies with other chemotherapeutic drugs to enhance efficacy and overcome resistance.
