“…3 Minoxidil is used to control blood pressure by relaxing and dilating the blood vessels, and it is always used in combination with beta-blockers and diuretics in order to prevent its side effects. 4 Several analytical techniques such as High Pressure Liquid Chromatography (HPLC), 5,6 Liquid Chromatography-Mass Spectrometry (LC-MS), 7,8 uorescence, 9,10 electrochemical, 11,12 and UV-visible spectroscopy 13,14 are reported for the analysis of two vasodilator drugs (amlodipine besylate and minoxidil) in pure pharmaceutical formulations and tablets. Unfortunately, these methods require more time for analysis, expensive instrumentation, and moreover, their applicability is limited only to the laboratory.…”
