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