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

While it is readily available in numerous forms, including patches, lozenges, and tablets, the nasal spray formulation is particularly developed for fast absorption through the nasal mucosa.
The nasal cavity is extremely vascularised (rich in blood vessels), permitting the medication to go into the bloodstream directly, bypassing the digestive system and the "first-pass metabolic process" of the liver. This leads to a fast beginning of action, normally within 5 to 10 minutes, making it ideal for dealing with severe flares of pain.
Indicators for Use in the UK
In the UK, fentanyl nasal sprays are strictly accredited for the management of development discomfort (BTP) in grownups who are already getting maintenance opioid therapy for chronic cancer pain.
