摘要: Abstract The skin disposition of topically applied lidocaine hydrochloride was determined in steady-state permeation conditions by mass spectrometry imaging (MSI). distribution pig ear assessed using matrix-assisted laser desorption/ionization–time-of-flight (MALDI-TOF-MS) with images examined BioMap software. Following the detection intrinsic signals lidocaine, concentration–distance curve obtained brightness analysis ([M+H+]: m / z 235.18). Although concentration profile MALDI-TOF-MS did not completely correspond calculated from profile, could be detected. These results demonstrated that MSI might a useful method to determine non-radiolabeled or non-fluorescent drugs.
