Mechanism of action

Paclitaxel is a microtubule-stabilizing agent that binds to β-tubulin dimers within assembled microtubules, preventing their disassembly. This disrupts the dynamic instability required for normal mitotic spindle function, leading to G2/M phase cell cycle arrest. The resulting mitotic block triggers apoptosis in rapidly dividing cancer cells.
