Fentanyl is an extremely potent artificial opioid analgesic, estimated to be 50 to 100 times more powerful than morphine. While it is offered in various kinds, including spots, lozenges, and tablets, the nasal spray formulation is specifically developed for quick absorption through the nasal mucosa.
The nasal cavity is extremely vascularised (abundant in blood vessels), allowing the medication to enter the blood stream directly, bypassing the digestion system and the "first-pass metabolism" of the liver. This leads to a quick beginning of action, usually within 5 to 10 minutes, making it ideal for treating acute flares of pain.
