[Paclitaxel (Taxol)].
The paclitaxel (TAXOL); Bristol-Myers Squibb Company) represents first agent from novel class of antineoplastic drugs--taxanes to enter routine clinical practice. Paclitaxel interferes with microtubular polymerization by promoting abnormal assembly of microtubules and inhibiting their subsequent disassembly. Pharmacokinetics of paclitaxel has been intensively studied. There are indications for nonlinear pharmacokinetics when paclitaxel is administered as a short infusion and at higher doses. Neurotoxicity, mucositis, and leukopenia correlate with some pharmacokinetic parameters. The clinical development of paclitaxel was initially hampered by hypersensitivity reactions. Current dosage regiments with premedication reduced the incidence of these events to 3%. The major dose-limiting adverse effect of paclitaxel is neutropenia. Significant activities were reported especially in patients with advanced ovarian, breast, non-small cell lung cancer (NSCLC), head and neck cancer and in other types of tumours. Long-term follow-up will also allow the effects of the drug on patient survival to be determined. At present combination of Taxol (paclitaxel) with cisplatin clearly improves the duration of progression-free survival and of overall survival compared with cyclophosphamide and cisplatin in women ovarian cancer. Recently was TAXOL (paclitaxel) registered in Czech republic for treatment of patients with advanced metastatic ovarian carcinoma and in patients with metastatic breast cancer after failure of the standard therapy.
