ABSTRACT
This report describes a specific and precise HPLC method for the quantification of torsemide in human plasma. The procedure included an efficient solid phase extraction, and the HPLC analysis used a phosphate buffer/acetonitrile mobile phase with a C18 column and ultraviolet detection at 288 nm. The mean absolute recovery ranged between 91.9% and 118.0%. The limit of detection was determined to be 0.010 µg/mL. The method described is suitable for torsemide plasma monitoring and pharmacokinetic studies. Data of three healthy volunteers are presented.
