Pain management is a vital element of palliative and oncological care in the United Kingdom. For patients experiencing breakthrough discomfort— sudden flares of extreme discomfort that “break through” the routine 24/7 discomfort medication— standard oral analgesics frequently act too gradually. Recently, fentanyl nasal sprays have emerged as an important tool for clinicians in the UK.

Fentanyl is a highly potent artificial opioid analgesic, estimated to be 50 to 100 times more effective than morphine. While it is available in various types, including spots, lozenges, and tablets, the nasal spray formulation is particularly created for rapid absorption through the nasal mucosa.

The nasal cavity is extremely vascularised (rich in capillary), permitting the medication to enter the blood stream straight, bypassing the gastrointestinal system and the “first-pass metabolism” of the liver. This results in a rapid onset of action, typically within 5 to 10 minutes, making it ideal for dealing with severe flares of pain.
