In end-stage renal disease, which narcotic is preferred due to hepatic elimination?

• A. Morphine
• B. Hydromorphone
• C. Fentanyl
• D. Oxycodone

Answer: (C)

In end-stage renal disease, choose opioids that are cleared by the liver with no active metabolites that rely on the kidneys. Fentanyl fits this pattern because it is predominantly hepatically metabolized to inactive compounds and has minimal renal excretion, so it is less likely to accumulate or cause prolonged toxicity in ESRD. Morphine and hydromorphone, by contrast, produce active or potentially neurotoxic metabolites (such as morphine-6-glucuronide and hydromorphone-3-glucuronide) that can build up when the kidneys aren’t functioning well, leading to increased sedation and respiratory depression. Oxycodone is also metabolized in the liver but its metabolites can accumulate as well, making it a less ideal choice than fentanyl in this setting. So the best option for ESRD due to hepatic elimination is fentanyl.
