About

Paclitaxel is a highly effective antineoplastic agent belonging to the taxane class of chemotherapy drugs. It is widely used in the treatment of various solid tumors, including ovarian cancer, breast cancer, non-small cell lung cancer, and Kaposi's sarcoma. Paclitaxel exerts its cytotoxic effects by interfering with microtubule function, a critical component of cell division. Specifically, it promotes the assembly of microtubules from tubulin dimers and stabilizes them, preventing depolymerization. This stabilization leads to the inhibition of normal dynamic reorganization of the microtubule network, which is essential for interphase and mitotic cellular functions. Consequently, cells become arrested in the G2/M phase of the cell cycle, leading to apoptosis. Its administration is typically intravenous, often requiring premedication to mitigate hypersensitivity reactions.
