Which statement about food and drug interactions is true?
a. Foods alter drug absorption and metabol-ism but not drug action.
b. Medications are best absorbed on an empty stomach.
c. Patient discomfort is the food and drug interaction of most concern.
d. Some foods can inhibit CYP isoenzymes and alter drug metabolism.
D
Grapefruit juice inhibits CYP3A4, which lowers the metabolism of some drugs, leading to toxic effects of drugs affected by these isoenzymes. Foods can alter all pharmacokinetic and pharma-codynamic processes. Not all medications are absorbed better on an empty stomach; some require certain foods to enhance absorption. Patient comfort is a concern, but it is not as important as more severe and possibly life-threatening food and drug interactions.
