由于催化反应时酶对底物化学结构有一定的要求,因此不同化学结构的药物,其代谢的情况不同。 药物代谢的酶 Enzymes for Drug Metabolism 第I相生物转化是官能团化反应,是在体内多种酶系的催化下,对药物分子引入新的官能团或改变原有的官能团的过程。参与药物体内I相生物转化的酶类,主要是氧化-还原酶和水解酶。 细胞...

2. Factors such as age, gender, race, environment, and drug treatment may have considerable influence on the activity of these enzymes. 3. There are now well-established in vitro techniques for assessing the role of specific cytochrome P450 enzymes in the metabolism of drugs, as well as the...
Absorption, distribution, metabolism, and elimination In order to produce an effect, a drug must reach its target site in adequate concentration. This involves several processes embraced by the general termpharmacokinetics. In general, these processes are: (1) administration of the drug, (2) absorp...
163Gut microbiota can directly affect drug metabolism in several manners, including generating enzymes that degrade or catalyze a drug molecule, competing with drug molecules for a metabolic enzyme, altering the metabolic levels of drugs in the host, or generating enzymes that stimulate metabolites ...
