Alfentanil
別名: Alfenta, Fanaxal, Fentalim, Limifen, Rapifen
Alfentanil is a **highly potent opioid medication** used strictly for anesthesia and severe pain management. * **Professional Use Only:** This drug is only administered by veterinary professionals in a clinical setting where advanced patient monitoring (like ECG and oxygen tracking) is available. * **Safety:** Because it can slow breathing and heart rate, your pet will be closely monitored throughout the entire procedure. * **Post-Anesthesia:** Your pet may be groggy or sleepy after the procedure, which is a normal effect of opioid anesthetics.
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。

- > **Critical Warning:** Because of the drug's potency and potential for significant adverse effects, it should **only** be used in situations where patient vital signs can be continuously monitored. * **Dose Adjustments:** Initial dosage reduction may be required in geriatric or debilitated patients, particularly those with diminished cardiopulmonary function or liver disease. * **Muscle Rigidity:** Dose-related skeletal muscle rigidity is not uncommon; neuromuscular blockers are routinely used in conjunction. * **Laboratory Artifacts:** May increase plasma levels of amylase or lipase secondary to increased biliary tract pressure. Values may be unreliable for 24 hours post-administration.
藥物相互作用
- CYP3A4 Inhibitors (erythromycin, cimetidine, ketoconazole, itraconazole, fluconazole, diltiazem): May increase the half-life and decrease the clearance of alfentanil leading to prolonged effect and an increased risk of respiratory depression
- Beta-blockers: May produce bradycardia or hypotension if used concurrently with alfentanil
- Other anesthetic agents: May produce bradycardia or hypotension; respiratory or CNS depression may be exacerbated
- Inhaled anaesthetics: Reduces the dose requirements of concurrently administered anaesthetics by at least 50%
- Monoamine oxidase inhibitors (MAOIs): Risk of serotonin toxicity
