An increase in the activity of these enzymes leads to a decrease in the concentration and effect of an administered drug. The cytochrome P450 enzymes are a group of enzymes in the liver that are responsible for the metabolism of most drugs. Conversely, a decrease in enzyme activity leads to an increase in drug concentration and effect. Metabolism of drugs is the process through which the body converts (alters or modifies) drugs into forms that are more or less active (for example, by converting drugs that are given in inactive forms into their active forms that actually produce the desired effect) or that are easier for the body to eliminate through the kidneys.

Some medications may be better absorbed if taken with food or may have more favorable blood levels if taken with other medications that affect metabolic enzymes. Not all drug interactions are bad.
