What is Fentanyl Nasal Spray?
Fentanyl is a highly potent synthetic opioid analgesic, estimated to be 50 to 100 times more powerful than morphine. While it is offered in different kinds, consisting of patches, lozenges, and tablets, the nasal spray solution is particularly developed for fast absorption through the nasal mucosa.
The nasal cavity is extremely vascularised (abundant in blood vessels), allowing the medication to go into the bloodstream directly, bypassing the digestion system and the "first-pass metabolism" of the liver. This leads to a fast onset of action, generally within 5 to 10 minutes, making it ideal for dealing with intense flares of pain.
