Plasma protein binding monitoring of therapeutic drugs in patients using single set of hollow fiber centrifugal ultrafiltration
Digital explosion of news articles and data from a computer screen, symbolizing information overload, digital chaos, and media consumption
Abstract Aim: Plasma protein binding (PPB), as a significant influenced factor of pharmacokinetic and pharmacodynamic properties of a medicine, is a suitable index for therapeutic drug monitoring (TDM) strategies. A suitable measurement technique of PPB of patients is in urgent need and attracts many analysts’ attention. Results & methodology: In this study, a novel method was proposed to analyze free drug concentration and total drug concentration (Ct) successively in one unit with a sample. All RSDs were less than 3%. The absolute recovery of Ct ranged from 98.1 to 101.2%. Discussion & conclusion: It is extremely valuable to consider PPB...
