In the last few years, fentanyl nasal sprays have become a crucial 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 effective than morphine. While it is readily available in various forms, consisting of patches, lozenges, and tablets, the nasal spray solution is specifically designed for rapid absorption through the nasal mucosa.
The nasal cavity is extremely vascularised (abundant in blood vessels), enabling the medication to go into the bloodstream straight, bypassing the digestion system and the "first-pass metabolism" of the liver. This results in a rapid onset of action, normally within 5 to 10 minutes, making it perfect for treating severe flares of pain.
