Which statement about food and medication interactions is most accurate?
All medications are best absorbed on an empty stomach.
Client discomfort is the food and medication interaction of highest concern.
Foods can alter medication absorption and metabolism but not the action of the medication.
Some foods can inhibit cytochrome P450 (CYP) isoenzymes and alter medication metabolism.
The Correct Answer is D
Certain foods can interact with medications by inhibiting or inducing cytochrome P450 (CYP) enzymes, which play a crucial role in drug metabolism ¹. This can alter the way the body processes medications and affect their efficacy and safety ¹.
Option A is not correct because not all medications are best absorbed on an empty stomach. Some medications should be taken with food to improve absorption or reduce side effects ¹.
Option B is not correct because client discomfort is not the only concern when it comes to food and medication interactions.

Option B is incorrect because donepezil does not decrease acetylcholine in the periphery to increase movement.
Option C is incorrect because donepezil does not delay the transmission of acetylcholine at the neuronal junction.
Option D is incorrect because donepezil does not bind dopamine at neuron receptor sites to increase ability.
