In contrast, some drugs have an inhibitory effect on enzymes, building the shopper a lot more delicate to other prescription drugs metabolized in the motion of All those enzymes. By way of example, monoamine oxidase inhibitors (MAOIs) are prescribed as antidepressants since they block monoamine oxidase, the enzyme that breaks down serotonin and dopamine, Therefore increasing the concentration of those chemical compounds in the central anxious technique.

If check here some of the drug is absorbed within the intestine in the bloodstream, Portion of the absorbed part could possibly be damaged down by liver enzymes, whereas the remaining section escapes into the final circulation.
