A fast and accurate liquid chromatographic method with tandem mass spectrometric detection has been validated in order to assure quantification of rilmenidine in human serum. The fragmentation pathway of protonated rilmenidine was studied using high-resolution mass spectrometry (HRMS). This study compared selectivity, linearity, accuracy, precision, extraction efficiency, matrix effect and sensitivity using common liquid–liquid extraction (LLE) and solid-phase extraction (SPE) procedures. Several differences between the LLE and SPE have been observed in terms of linearity, accuracy, precision and matrix effect. The developed method involving SPE was found to be accurate, reproducible, robust and suitable for quantitative analysis of rilmenidine in serum samples obtained from patients under antihypertensive treatment.
