Which drug has an onset of action of 1 minute?

• A. Fentanyl
• B. Meperidine
• C. Naloxone
• D. Butorphanol

Answer: (C)

The drug that has an onset of action of approximately 1 minute is naloxone. Naloxone is an opioid antagonist that is used primarily to reverse the effects of opioid overdose. Its rapid onset of action is crucial in emergency situations where opioid overdose has occurred, as it allows for immediate restoration of normal respiratory function and consciousness in patients affected by opioid toxicity. Fentanyl and butorphanol, while also acting relatively quickly, typically have slightly longer onset times than naloxone. Meperidine, though it is an opioid, has a longer onset of action compared to naloxone. Hence, among these choices, naloxone is uniquely recognized for its swift action, making it an essential medication in emergency medical settings.
