The main site of drug metabolism within the body occurs in the liver, however, this is not the only site in which metabolism of drugs occurs, this will be discussed later. The liver ensures drugs are subjected to attack by various metabolic enzymes; the main purpose of these enzymes is to convert a non-polar drug into more polar molecules ...

Metabolism is often divided into two phases: Phase 1 metabolism involves chemical reactions such as oxidation (most common), reduction and hydrolysis. There are three possible results of phase 1 metabolism. The drug becomes completely inactive. In other words, the metabolites are pharmacologically inactive.

2 Absorption, Distribution, Metabolism, and Elimination. Jim E. Riviere. The four key physiological processes that govern the time course of drug fate in the body are absorption, distribution, metabolism, and elimination, the so-called ADME processes.Pharmacokinetics, the study of the time course of drug concentrations in the body, provides a means of quantitating ADME parameters.

Two types of enzymes are involved in metabolism: Phase I Metabolism. These enzymes modify the drug chemically by processes such as oxidation, reduction and hydrolysis or by the removal and addition of an active group. Phase II Metabolism

Overview: Phase I metabolism . oxidation (via cytochrome P450), reduction, and hydrolysis reactions ; phase I reactions convert a parent drug to more polar (water soluble) active metabolites by unmasking or inserting a polar functional group (-OH, -SH, -NH2) geriatric patients have decreased phase I metabolism

Metabolism pathways include the basic chemical reactions that provide cells with the energy to remain alive and repair themselves. Cellular respiration is the central metabolic activity, and it operates through three different pathways — glycolysis, the Krebs cycle, and oxidative phosphorylation — that make energy-rich molecules that fuel cells.

The second phase of drug metabolism is conjugation, which is a Phase I metabolite joining to another compound. Conjugation is very important, as this is the phase that increases the water solubility of the drug, which is needed to allow excretion of the drug. ...

Drug Response With Advancing Age. Aging, Effects on Drug Metabolism and Drug Response – Many drugs have different therapeutic effects as well as potential adverse drug reactions, depending on a person’s age. The very young and the very old often have limited liver function, which affects the ways in which the liver metabolizes drugs, resulting in lower thresholds for toxicity and ...
