Pharmacokinetics of New Solubilizer in Intravenous Micelle Formulation of Paclitaxel in Mice

Paclitaxel is an antitumor agent with poor water solubility and its pharmacokinetics are nonlinear. Cremophor EL. a surfactant used in the formulation of paclitaxel. may cause adverse effects. New solubilizer(Aceporol 460) was developed to reduce side effects of Cremophor EL and to increase the effect of drug as surfactant used in the intravenous micelle formulation of anticancer drug paclitaxel. We studied easy, rapid quantitative determination of Aceporol 460 in mouse plasma samples. which was achieved by complexation of the compound with the Coomassie brilliant blue G-250 dye in protein-free extracts.
