BOOK EXCERPT:
This timely reference discusses mass spectrometry in drug metabolism and pharmacokinetic studies. With contributions by professionals from the pharmaceutical industry, this book begins with a review of current mass spectrometry techniques and applications, followed by discussions of various methods for using MS in drug metabolism studies and pharmacokinetics. Highlighting the critical importance of ADME studies for understanding how a drug is absorbed, distributed, metabolized, and excreted by the body, the book s focuses on the use of LC/MS and MALDI-MS. This is a valuable reference for scientists in the pharmaceutical industry, medicine, academia, and even those working in homeland defense.

BOOK EXCERPT:
When a dose of drug is administered, three main phases of drug action may be distingushed. In the "pharmaceutical" phase the dosage form disintegrates, the active substance dissolves and becomes available for absorption. The second phase ("pharmaco kinetic" phase) includes absorption, distribution, metabolism, and excretion. That fraction of the dose which finally reaches the circulation after absorption will be available for biological action in the third, or "pharmacodynamic" phase when the drug reaches the target tissues and a drug-receptor interaction takes place. The objectives in studies of drug metabolism are: (a) to identify the pathways by which drugs are transformed in the body; (b) to ascertain quantitatively the importance of each pathway and intermediate; (c) to identify and quantify endogenous constituents influenced by the drug or its metabolites which may interfere with common metabolic processes. Since metabolites usually differ from their precursors by only a single chemical group, the resulting metabolic pathways generally consist of a series of closely related compounds. Mass spectrometry is uniquely suited for the analysis of drugs and metabolites for several reasons: only a minimal amount of sample preparation is needed, closely related compounds can be analyzed in a single step, structures can often be deduced directly from the mass spectra without the need for pure reference spectra, and constituents can be quantified with relative ease even when present in fractional nanogram quantity.

BOOK EXCERPT:
Drug metabolism comprises the identification, characterization, and quantification of the chemicals or compounds produced in an animal or human upon administration of a drug. Research practices not only require the chemical structure but also aim to determine the pharmacological activities and/or toxicity of these compounds. This is first performed in animals, as studies attempt to identify and quantify metabolites, and later in humans, with care to further characterize metabolites that are either unique to or produced disproportionately in humans compared to animals. Characterization includes the determination of enzyme systems or other biological mechanisms that produce each identified metabolite; this information is used to predict potential drug-drug interactions with other compounds that increase or decrease metabolite formation and sources of biological variability in response or toxicity with varying patient genetics, which affect CYP isoform expression. This book’s purpose is to provide some understanding of the biology and current technology applied in the field of drug metabolism.

BOOK EXCERPT:
In order to avoid late-stage drug failure due to factors such as undesirable metabolic instability, toxic metabolites, drug-drug interactions, and polymorphic metabolism, an enormous amount of effort has been expended by both the pharmaceutical industry and academia towards developing more powerful techniques and screening assays to identify the metabolic profiles and enzymes involved in drug metabolism. This book presents some in-depth reviews of selected topics in drug metabolism. Among the key topics covered are: the interplay between drug transport and metabolism in oral bioavailability; the influence of genetic and epigenetic factors on drug metabolism; impact of disease on transport and metabolism; and the use of novel microdosing techniques and novel LC/MS and genomic technologies to predict the metabolic parameters and profiles of potential new drug candidates.
