Plasticizer extraction of Taxol infusion solution from various infusion devices.

Taxol solution extracts the plasticizer DEHP (di(2-ethylhexyl)phthalate) from polyvinyl chloride (PVC) materials. In order to minimize patient exposure to DEHP, Taxol solutions should be prepared and administered in PVC-free materials. Particulate matter may form in Taxol infusion solution over time, so that in-line filtration with microporous membranes not greater than 0.22 microns is advisable. The purpose of this study was to evaluate the suitability of various administration- and in-line filter-sets for Taxol application. The extent of leached DEHP was determined using a Reversed Phase HPLC assay specific for DEHP. The four tested administration-sets, labeled as PVC-free, were all found to be suitable for Taxol application. The tested standard PVC-lined administration-set should not be used for Taxol application. Baxter Intermate LV 250 can be recommended as a disposable infusion device for ambulatory Taxol application. It can be connected with all the tested filter sets.
