**Core Concept**
Flumazenil is a benzodiazepine antagonist used to reverse the effects of benzodiazepines in cases of overdose or sedation. The duration of action of flumazenil is a critical factor in its clinical use, as it determines how long its effects will last and when additional doses may be needed.

**Why the Correct Answer is Right**
Flumazenil's duration of action is approximately 60 minutes, allowing it to effectively reverse the sedative effects of benzodiazepines without causing prolonged sedation. This is due to its rapid onset of action and relatively short half-life. Flumazenil binds to the benzodiazepine receptor, displacing the benzodiazepine molecule and restoring normal GABA receptor function. The short duration of action of flumazenil is advantageous in clinical settings, as it minimizes the risk of prolonged sedation and allows for repeated dosing as needed.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect, as this option is too short and would not provide adequate reversal of benzodiazepine effects.
**Option B:** Incorrect, as this option is too long and may lead to prolonged sedation and potential rebound effects.
**Option C:** Incorrect, as this option is not a commonly recognized duration of action for flumazenil.

**Clinical Pearl / High-Yield Fact**
It is essential to monitor patients for signs of benzodiazepine withdrawal after flumazenil administration, as they may experience rebound anxiety or seizures. Flumazenil should be used cautiously in patients with a history of benzodiazepine dependence.

**Correct Answer:** 60 minutes.
