Determination of Mebudipine in Human Plasma by Liquid Chromatography-tandem Mass Spectrometry.

In previous studies, mebudipine, a dihydropyridine calcium channel blocker, showed a considerable potential to be used in cardiovascular diseases. The aim of the current study was to develop a valid method using reversed-phase high performance liquid chromatography coupled with electrospray ionization mass spectrometry to assay mebudipine in the human plasma. Separation was achieved on a Zorbax Eclipse(®) C18 analytical column using a mobile phase consisted of methanol/water (90:10, v/v).
