What is Fentanyl Nasal Spray?
Fentanyl is a highly powerful synthetic opioid analgesic, estimated to be 50 to 100 times more effective than morphine. While it is available in different types, including spots, lozenges, and tablets, the nasal spray formula is particularly designed for fast absorption through the nasal mucosa.
The nasal cavity is highly vascularised (rich in blood vessels), permitting the medication to enter the blood stream straight, bypassing the gastrointestinal system and the "first-pass metabolic process" of the liver. This results in a quick start of action, typically within 5 to 10 minutes, making it ideal for dealing with intense flares of discomfort.
Signs for Use in the UK
