Summary
A procedure for the rapid, quantitative isolation of amiodarone and its main metabolite (desethylamiodarone) from plasma with SEP-PAK™ silica cartridges is described together with a sensitive high performance liquid chromatographic assay for the quantitative determination of the drugs.
The recovery of amiodarone and its metabolite was greater than 80% over an investigated range of 0.1–5μg/ml of plasma and the limit of quantitation by the assay was 50 ng/ml of plasma.
The column extraction of amiodarone and its metabolite coupled with the chromatographic versatility of the method make it suited for either detailed pharmacokinetic studies and routine plasma analysis of amiodarone.
