Polyethylene glycols are synthetic polymers composed of repeating oxyethylene subunits, which have been known for non-toxic, non-immunogenic, non-antigenic, good solubility in water and therefore approved for pharmaceutical applications. Recently, attachment or amalgamation of polyethylene glycols to therapeutic small molecules, peptides, proteins, or nanoparticles has become a mature technology for the sake of improving their pharmacokinetic and pharmacological profiles, also referred to as PEGylation. By comparison, there are only a few PEGylated pharmaceuticals have been registered for further clinical trials and even less was approved for marketing. High failure rate of PEGylated pharmaceuticals in pre-clinical and clinical trials could be majorly attributed to their unclear pharmacokinetic behaviors. Therefore, the in vivo fate of the PEGylated pharmaceuticals for the various routes of administration needs to be thoroughly investigated An accurate in vivo pharmacological study thereof highly depends on the precise detection of polyethylene glycols as well as their fragments in biological matrixes. The goal of this review is to highlight the analytical methods that were developed and applied to evaluate the polyethylene glycols in pharmaceutical ingredients and excipients, which bring us closer to bridging the gap between the development of polyethylene glycol-based drug delivery systems and their clinical application.
