FIGURE 16.4 General scheme for the role played by reactive drug metabolites in causing a variety of adverse reactions. The reactive metabolites usually account for only a small fraction of total drug metabolism and are too unstable to be chemically isolated and analyzed. In many cases, covalent binding of these metabolites to tissue macromolecules only occurs after their formation exceeds a critical threshold that overcomes host detoxification and repair mechanisms.

variability in incidence of these reactions reflects varying activity in the parallel pathways involved in metabolizing drugs to either nontoxic or reactive metabolites. In some cases, it has been possible to actually relate the risk of an adverse drug reaction to polymorphic drug-metabolizing phenotype.

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
