Taxol: a promising new drug of the '90s.
Taxol (paclitaxel, Bristol-Myers Squibb Company, Princeton, NJ), a drug extracted from the stem bark of the western yew, shows great promise as an antineoplastic agent for ovarian, breast, nonsmall cell lung, and head and neck cancers; melanoma; and leukemia. Although Taxol first was isolated in 1971, completion of many phase I studies was delayed until 1988, primarily because the drug caused severe hypersensitivity reactions. Other side effects of Taxol include cardiotoxicity, nausea and vomiting, diarrhea, mucositis, myelosuppression, tingling and numbness of the hands and feet, myalgia and arthralgia, alopecia, fatigue, headache, irritation at the injection site, and taste changes. Nursing care includes measures for preventing or minimizing side effects, close assessment and monitoring of potential side effects, patient education, and support. Because of the environmental impact of harvesting the western yew for Taxol, semisynthetic preparations such as taxotere are being explored.
