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 different forms, including patches, lozenges, and tablets, the nasal spray formula is specifically created for quick absorption through the nasal mucosa.
The nasal cavity is extremely vascularised (abundant in blood vessels), permitting the medication to get in the blood stream straight, bypassing the digestive 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 perfect for treating acute flares of pain.
