What is Fentanyl Nasal Spray?
Fentanyl is a highly potent artificial opioid analgesic, estimated 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 developed for quick absorption through the nasal mucosa.
The nasal cavity is extremely vascularised (rich in blood vessels), enabling the medication to go into the blood stream directly, bypassing the digestive system and the "first-pass metabolic process" of the liver. This leads to a rapid start of action, generally within 5 to 10 minutes, making it ideal for dealing with intense flares of discomfort.
Indications for Use in the UK
