Induction of Drug Metabolism •Many currently used drugs are well known to induce their own metabolism or the metabolism of other drugs. Some examples are the anticonvulsant medications phenobarbital and carbamazepine, and even St. John’s Wort. •Cigarette smoking can cause increased elimination of theophylline and other compounds. Drug Metabolism What is mean by: drug metabolism or drug biotransformation. metabolism plays an essential role in the elimination of drugs and other foreign ingested chemicals (xenobiotics) from the body In some cases, especially during oxidative metabolism, numerous chemical procarcinogens formFile Size: KB.
Role of Metabolism in Drug discovery 36 • In drug development it is important to have an information on the enzymes responsible for the metabolism of the candidate drug • Invitro Studies can give information about • Metabolite stability • Metabolite profile • Metabolite Identification • CYP induction/Inhibition • Drug/Drug. Safe and effective drug treatment is not only a function of the physical and chemical prop-erties of drugs, but also a function of how the human body responds to the administration of medication. The study of the bodily processes that affect the movement of a drug in the body is referred to as pharmacokinetics. principles of chemistry and biology to the creation of knowledge leading to the introduction of new therapeutic agents. So, the primary objective of medicinal chemistry is the design and discovery of new drugs inside a living organism is called drug metabolism or drug biotransformation. 5 The pharmacodynamic phase comprises the process of.
Drug metabolism Drug metabolism ON-TARGET EFFECTS An important concept in drug toxicity is that an adverse effect may be an exaggeration of the desired pharmacologic action due to alterations in exposure to the drug (see Fig. ). This can occur by deliberate or accidental dosing error, by alterations in the pharmacokinetics of the drug (e.g., due. If a candidate drug has a human- Existing in vitro systems and in vivo testing in animal specific (or more often, a human-predominant) drug metab- species have not always accurately predicted human phar- olite, the use of preclinical toxicity testing in animal species is macokinetics or the human-specific drug metabolism path- quite limited. Since the publication of the first edition of Drug-Drug Interactions in , our knowledge of the various human drug-metabolizing enzyme systems and drug transporters has continued to grow at a rapid pace.
