Abstract

Polymeric prodrugs have gained significant popularity as a strategy to enhance the bioavailability and improve the pharmacokinetic properties of active pharmaceutical ingredients (API). Since the amount of the API in a polymeric prodrug product directly impacts both safety and efficacy, there is a pressing need for robust and accurate analytical methods to quantify the API in these formulations. Presently, drug quantification methods include reversed-phase high-performance liquid chromatography (RP-HPLC) and size exclusion chromatography (SEC)-based molecular weight determination. Even though these methods are highly precise and reproducible, a deep understanding of chromatography is required for complex method development, including optimization of the elution profile and selecting the appropriate column and mobile phase. In this chapter, we introduce the automated elemental analyzer for drug quantification, which is simple to use and does not require special method development.
