Download or read book In Vitro Drug Metabolism Studies Using Human Liver Microsomes written by Rajesh Sonti and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metabolism of most pharmaceutical drugs occurs in the liver. In drug metabolism, enzymes convert drugs to highly water-soluble metabolites to facilitate excretion from the body. Thus, in vitro models for studying drug metabolism usually target hepatocytes or subcellular liver fractions like microsomes, cytosols, or S9 fractions with high concentrations of specific enzymes. The most popular subcellular fraction used during drug discovery tends to be the microsomes, as these are easy to prepare and store, are amenable to high throughput screening, and are a relatively low-cost option. Understanding the metabolic stability and kinetics of glucuronidation of an investigational drug is crucial for predicting the pharmacokinetic parameters that support dosing and dose frequency. This chapter provides detailed information about metabolite profiling, metabolic stability, glucuronidation kinetics, reactive metabolites identification, CYP enzyme inhibition, and general protocols using human liver microsomes.

Download or read book Drug Discovery and Evaluation Methods in Clinical Pharmacology written by H.Gerhard Vogel and published by Springer Science & Business Media. This book was released on 2010-12-15 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drug Discovery and Evaluation has become a more and more difficult, expensive and time-consuming process. The effect of a new compound has to be detected by in vitro and in vivo methods of pharmacology. The activity spectrum and the potency compared to existing drugs have to be determined. As these processes can be divided up stepwise we have designed a book series "Drug Discovery and Evaluation" in the form of a recommendation document. The methods to detect drug targets are described in the first volume of this series "Pharmacological Assays" comprising classical methods as well as new technologies. Before going to man, the most suitable compound has to be selected by pharmacokinetic studies and experiments in toxicology. These preclinical methods are described in the second volume „Safety and Pharmacokinetic Assays". Only then are first studies in human beings allowed. Special rules are established for Phase I studies. Clinical pharmacokinetics are performed in parallel with human studies on tolerability and therapeutic effects. Special studies according to various populations and different therapeutic indications are necessary. These items are covered in the third volume: „Methods in Clinical Pharmacology".

Download or read book Metabolic Changes Induced by Alcohol written by Gustav A. Martini and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: In nearly all parts of the world, the consumption of alcohol is increasing, and the morbidity and mortality of diseases induced by alcohol are rising correspondingly. It has been stated that alcohol is consumed because it pro duces intoxication. This effect is due to its toxicological influence on the central nervous system with the resulting functional disturbances. For many years, the concept that alcoholic liver disease was of nutritional origin and only indirectly related to alcohol consumption and metabolism was accepted. Opinion has changed gradually in recent years and tends now to regard alcohol itself through its combustion, as responsible for many metabolic disorders. Interest in this problem has increased during the past decade, and numerous papers bearing on this subject have appeared. It seems that the oxidation of alcohol in the liver interferes in many ways with the intermediary metabolism of lipids, carbohydrates and proteins, including enzymes and hormones, and exerts damaging influence on the liver, the musculature, the heart, the brain and the kidneys. The "Workshop Symposium" brought together a limited number of the scientists involved in the new development, biochemists, physiologists, pharmacologists, pathologists and clinicians from eight European countries and from the United States and allowed a very lively and informal exchange. The symposium was honored by the presence of Sir Hans Krebs, whose vast experience stimulated the discussion. It is a great pleasure to dedicate this volume to Sir Hans on the occasion of his 70th birthday on August 25th.

Download or read book Drug Metabolism written by Katherine Dunnington and published by BoD – Books on Demand. This book was released on 2021-12-22 with total page 110 pages. Available in PDF, EPUB and Kindle. 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.
