This is the first article in a four-part series exploring the quantitative assessment of drugs and their metabolites in biological fluids (such as blood, plasma, and urine) and tissue homogenates using liquid chromatography–mass spectrometry (LC–MS).
This article is the first of four on the bioanalysis of small-molecule drugs and metabolites by liquid chromatography–mass spectrometry (LC–MS). In this article, we provide an overview of the fundamentals, workflow, regulations, and modern trends on these quantitative assays.
In the pharmaceutical industry, method validation is essential. But what are the best practices? We review regulatory requirements, validation parameters, methodologies, acceptance criteria, trends, and software tools.
