Mechanism of action

Paclitaxel is a taxane that binds to microtubule proteins and prevents their disassembly, causing cell cycle arrest in the G2/M phase and triggering apoptosis. The protein-bound formulation (nab-paclitaxel) uses albumin nanoparticles to deliver paclitaxel, improving solubility and potentially enhancing tumor uptake compared to conventional formulations.
