Graphene-Based Sensor for Voltammetric Quantification of Dapoxetine Hydrochloride: A Drug for Premature Ejaculation in Formulation and Human Plasma

“…Also, there is a serve lack of quantitative analysis of Dapoxetine drug either in biological fluids or in pharmaceutical formulation compared to this importance. These techniques include spectrophotometry, [8][9][10][11][12][13][14] liquid chromatography-tandem mass spectrometry (LC/MS/MS), 5,7 ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS), 6 ultra-performance liquid chromatography mass spectroscopy (UPLC-MS/UV), 15 high performance liquid chromatography, [16][17][18][19][20] and electrochemistry. [21][22][23] Table I.…”

“…However, LC-MS/MS methods [5][6][7] are expensive and not available in all clinical laboratories. Table I shows also the very low sensitivity of spectrophotometric, [8][9][10][11][12][13][14] some of chromatographic 15,16,[18][19][20] and elecz E-mail: hseldesoky@hotmail.com trochemical methods, [21][22][23] that they were inadequate for pharmacokinetic studies. On the other hand, chromatographic techniques have a lot of obstacles in the way of being not simple, required high maintenance cast, high acquisition cost, a large amount of high purity organic solvents and time-consuming extraction step.…”
