摘要: We have developed a specific and sensitive method aiming atdocetaxel (Taxotere®) determination in plasma of treatedpatients. This involved solid-phase extraction 1 ml plasmaonto carboxylic acid (CBA) grafted silica cartridges followed byreversed-phase liquid chromatography with UV detection. The bestselectivity was obtained through the use C18 Uptisphere® asstationary phase. low limit quantitation (LOQ:5 ng/ml) allowed measurements docetaxel up to 24 hours afterone-hour infusions dosages drug (60 mg/m2). Themethod applied successfully monitor levelswithin two protocols associating fixed either methotrexate or gemcitabine escalating doses Taxotere®.
