商品名：Sublimaze and generic brands; Fentora buccal tablets
Synthetic opiate analgesic. Fentanyl is approximately 80 to 100 times more potent than morphine. Fentanyl is an agonist for the mu-opiate receptors on nerves and inhibits release of neurotransmitters involved with transmission of pain stimuli (such as Substance P). The central sedative and euphoric effects are related to mu-receptor effects in the brain. Fentanyl has a wide safety profile with doses as high as 300 times the recommended dose not being lethal in spontaneously breathing dogs. It is highly lipophilic—approximately 1000 times more lipophilic than morphine, which produces rapid diff
Fentanyl citrate is used as an intravenous bolus or as a constant rate infusion (CRI) in animals for relief of pain, an adjunct for anesthesia, or as a sedative in combination with other CNS sedatives. Fentanyl administered IV will produce Fentanyl Citrate 307 F antinociceptive effects for approximately 2 hours. Most of the doses are based on empiricism and experimental studies. Oral buccal tablets have been used in people for treatment of breakthrough pain, but there has been only anecdotal experience with this use in animals. See Fentanyl, Transdermal for information about transdermal form.
