What is Fentanyl Nasal Spray?
Fentanyl is a highly potent synthetic opioid analgesic, estimated to be 50 to 100 times more powerful than morphine. While it is offered in various forms, consisting of patches, lozenges, and tablets, the nasal spray formulation is particularly developed for rapid absorption through the nasal mucosa.
The nasal cavity is extremely vascularised (rich in capillary), enabling the medication to enter the bloodstream straight, bypassing the digestive system and the "first-pass metabolism" of the liver. This leads to a quick onset of action, generally within 5 to 10 minutes, making it perfect for dealing with intense flares of discomfort.

How it Works: The Mechanism of Action
Fentanyl acts mainly on the mu-opioid receptors in the central nerve system (the brain and spine cord). By binding to these receptors, it inhibits the transmission of pain signals and changes the psychological understanding of pain.

This simulates the speed of intravenous administration without the requirement for needles, providing a non-invasive alternative for clients who may be struggling with queasiness or difficulty swallowing.
Medical Administration and Dosage
Prescribing fentanyl nasal spray in the UK follows a rigorous titration process. Since every client's level of opioid tolerance is different, the effective dose can not be predicted based upon their present daily opioid intake.
