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.
Function of Paclitaxel
1. Paclitaxel is a mitotic inhibitor drup used in the treatment of cancer.
2. Isolated the compound from the bark of the Pacific yew tree, Taxus brevifolia, and noted its antitumor activity in a broad range of rodent tumors.
3. Paclitaxel has since become an effective tool of doctors who treat patients with lung, ovarian, breast cancer, and advanced forms of Kaposi's sarcoma.
