Discomfort management is a crucial component of palliative and oncological care in the United Kingdom.

Over the last few years, fentanyl nasal sprays have become an essential tool for clinicians in the UK.

What is Fentanyl Nasal Spray?
Fentanyl is an extremely potent artificial opioid analgesic, approximated to be 50 to 100 times more powerful than morphine. While it is offered in various kinds, consisting of patches, lozenges, and tablets, the nasal spray solution is particularly created for rapid absorption through the nasal mucosa.
The nasal cavity is highly vascularised (abundant in capillary), enabling the medication to get in the blood stream straight, bypassing the digestion system and the "first-pass metabolic process" of the liver. This leads to a quick onset of action, typically within 5 to 10 minutes, making it perfect for treating intense flares of discomfort.
Indicators for Use in the UK
In the UK, fentanyl nasal sprays are strictly licensed for the management of advancement discomfort (BTP) in adults who are currently getting maintenance opioid treatment for persistent cancer discomfort.

How it Works: The Mechanism of Action
Fentanyl acts mainly on the mu-opioid receptors in the main nerve system (the brain and spine). By binding to these receptors, it inhibits the transmission of pain signals and changes the emotional perception of pain.
Due to the fact that the nasal spray is provided as a great mist, the fentanyl molecules penetrate the mucous membrane and go into the systemic blood circulation almost instantly.
