Effective on-line extraction of drugs from plasma using a restricted-access media column in column-switching HPLC equipped with a dilution system: application to the simultaneous determination of ER-118585 and its metabolites in canine plasma.

Abstract

The present paper describes the on-line extraction of drugs in plasma using a restricted-access media (RAM) column in a column-switching high performance liquid chromatography (HPLC) apparatus that was equipped with an on-line dilution system. The use of a six- to eightfold on-line dilution ratio for plasma samples resulted in almost 100% recovery of both… (More)
