What is Fentanyl Nasal Spray?
Fentanyl is an extremely powerful synthetic opioid analgesic, estimated to be 50 to 100 times more powerful than morphine. While it is readily available in numerous kinds, including spots, lozenges, and tablets, the nasal spray solution is particularly created for quick absorption through the nasal mucosa.
The nasal cavity is extremely vascularised (abundant in blood vessels), enabling the medication to enter the blood stream directly, bypassing the digestion system and the "first-pass metabolic process" of the liver. This leads to a fast beginning of action, usually within 5 to 10 minutes, making it ideal for treating intense flares of pain.
