Opioids · Pharmacology

Which opioid has an extremely short half-life (approx. 3-4 minutes) because it is rapidly metabolized by non-specific tissue and plasma esterases?

  1. Sufentanil
  2. Alfentanil
  3. Buprenorphine
  4. Remifentanil
Show answer and explanation

Correct answer: Remifentanil

Remifentanil is unique because its metabolism is independent of hepatic or renal function. Its rapid clearance allows for precise, minute-to-minute control during general anesthesia and immediate recovery after the infusion is stopped.
