Which statement about Flumazenil is true?

Which statement about Flumazenil is true?

• A. Is contraindicated in narcotic addicts
• B. Partially antagonizes thiopental
• C. Can produce seizures in chronic benzodiazepine users
• D. Has a longer elimination half-life compared to midazolam

Answer: (C)

Flumazenil is a selective competitive antagonist at the benzodiazepine binding site of the GABA-A receptor, used to reverse benzodiazepine-induced sedation. Abruptly blocking benzodiazepine effects in someone who is chronically using or dependent on benzodiazepines can precipitate withdrawal, and this withdrawal can trigger seizures. That’s why it can produce seizures in chronic benzodiazepine users, making that statement true. Flumazenil does not antagonize thiopental or other non-benzodiazepine sedatives, so the idea of partially antagonizing thiopental isn’t correct. Its half-life is short, generally shorter than that of many benzodiazepines like midazolam, so it does not have a longer elimination half-life than midazolam. It isn’t contraindicated solely because of narcotic addiction; caution is needed if there’s coexisting opioid use, but narcotic addiction alone isn’t a blanket contraindication.
