Discomfort management is a critical part of palliative and oncological care in the United Kingdom.

In recent years, fentanyl nasal sprays have emerged as an important tool for clinicians in the UK.

What is Fentanyl Nasal Spray?

Fentanyl is a highly potent synthetic opioid analgesic, estimated to be 50 to 100 times more effective than morphine. While it is offered in various types, consisting of patches, lozenges, and tablets, the nasal spray formula is particularly designed for quick absorption through the nasal mucosa.

The nasal cavity is extremely vascularised (rich in blood vessels), allowing the medication to enter the blood stream straight, bypassing the gastrointestinal system and the "first-pass metabolic process" of the liver. This leads to a quick onset of action, usually within 5 to 10 minutes, making it perfect for treating intense flares of pain.
