Grapefruit can influence certain heart medications by altering how they are metabolized.

• A. False
• B. True
• C. Sometimes
• D. Not applicable

Answer: (B)

Grapefruit can influence certain heart medications because it inhibits enzymes in the gut that normally break down these drugs. That inhibition raises how much of the drug gets absorbed, increasing blood levels and the medication’s effects, which can raise the risk of side effects or toxicity. This is true for specific meds that are processed by those intestinal enzymes, such as some statins and certain calcium channel blockers. The interaction isn’t universal for all heart drugs, and the magnitude depends on the particular medication and how much grapefruit is consumed, but the statement is correctly identifying a real, clinically important interaction. Always check for grapefruit-related guidance with any heart medication.
