title: Rapid and sensitive liquid chromatography-tandem mass spectrometry method for the estimation of nicorandil in human plasma.
abstract: A rapid and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method has been developed and validated for the estimation of nicorandil in human plasma. Nicorandil was extracted from human plasma using solid-phase extraction technique. Imipramine was used as the internal standard. A Betasil C18 column provided chromatographic separation of analytes followed by detection with mass spectrometry. The method involves a rapid solid-phase extraction from plasma, simple isocratic chromatography conditions and mass spectrometric detection that enables detection at nanogram levels. The proposed method has been validated for a linear range of 1.0-500.0 ng/mL with a correlation coefficient of > or =0.9993. The intra-run and inter-run precision and accuracy was within 10.0%. The overall recovery for nicorandil was 63.81%. The total run time was just 3.0 min.
