What Is The Paclitaxel
May 05, 2017

Paclitaxel was first isolated in 1971 from the Pacific yew and approved for medical use in 1993. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. Paclitaxel powder is a chemotherapy drug that is given as a treatment for some types of cancer. Paclitaxel powder is a mitotic inhibitor now used to treat patients with lung, ovarian, breast cancer, head and neck cancer, and advanced forms of Kaposi's sarcoma. Paclitaxel is also used for the prevention of restenosis.

Paclitaxel powder works by interfering with normal microtubule breakdown during cell division. Together with docetaxel, it forms the drug category of the taxanes. paclitaxel powder was the subject of a notable total synthesis by Robert A. Holton.

As well as offering substantial improvement in patient care, paclitaxel has been a relatively controversial drug. There was originally concern because of the environmental impact of its original sourcing, no longer used, from the Pacific yew. The assignment of rights, and even the name itself, to BMS were the subject of public debate and Congressional hearings.
