Flumazenil
別名: Romazicon, Anexate, Fadaflumaz, Flumage, Flumanovag, Flumazen, Fluxifarm, Lanexat
**What Pet Owners Should Know:** * **Hospital Use Only:** Flumazenil is an emergency and anesthetic reversal drug used strictly in a controlled veterinary hospital environment by trained professionals. * **Purpose:** It is used to quickly "wake up" pets who have been given benzodiazepine sedatives (like Valium/diazepam) or to treat accidental overdoses of these medications or human sleep aids like Ambien. * **Monitoring:** Because the drug wears off quickly (in about an hour), your pet will be closely monitored in the hospital to ensure they do not become sleepy again once the reversal agent wears off.
劑量必須由獸醫按你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。

給藥方式
可能的副作用
- Injection site reactions
- Vomiting
- Cutaneous vasodilatation
- Vertigo
- Ataxia
- Blurred vision
- Seizures (especially in patients with a history of chronic benzodiazepine use or tricyclic antidepressant toxicity)
- Potentially teratogenic at high dosages
- Seizures (especially in patients receiving long-term benzodiazepine therapy)
- Re-sedation (due to short half-life)
- Agitation or anxiety upon rapid awakening
注意事項與禁忌
- Known hypersensitivity to flumazenil or other benzodiazepines
- Patients receiving benzodiazepines for life-threatening conditions (e.g., status epilepticus, increased intracranial/CSF pressure)
- Serious tricyclic antidepressant (TCA) overdose
- Mixed overdoses where benzodiazepine reversal may precipitate seizures
- Baclofen or carisoprodol overdoses (may worsen clinical signs)
- Suspected tricyclic antidepressant overdose (can precipitate seizures)
- Patients receiving long-term benzodiazepine administration for seizure control or sedation (relative contraindication)
- **Important Warnings:** * **Short Half-Life:** Flumazenil has a shorter half-life (~1 hour) than many of the benzodiazepines it reverses. **Re-sedation** can occur once flumazenil wears off, requiring repeated dosing. * **Seizure Risk:** Use with extreme caution in patients with mixed drug overdoses or those dependent on benzodiazepines for seizure control, as rapid reversal can precipitate intractable seizures. * **Not a Universal Antidote:** It does not alter benzodiazepine pharmacokinetics (clearance/metabolism) and does not reverse opioids, alpha-2 agonists, or dissociative anesthetics.
藥物相互作用
- Cyclic Antidepressants (e.g., clomipramine, amitriptyline): Increased risk for seizures; concurrent use is contraindicated.
- Neuromuscular Blocking Agents: Not recommended to use flumazenil until neuromuscular blockade has been fully reversed.
- Tricyclic antidepressants (TCAs): Can precipitate seizures in patients with suspected TCA overdose
- Benzodiazepines (Diazepam, Midazolam, etc.): Antagonizes therapeutic effects (intended interaction)
- Tricyclic antidepressants: Increased risk of seizures if flumazenil is administered during a TCA overdose.
