Fentanyl is a highly potent artificial opioid analgesic, approximated to be 50 to 100 times more effective than morphine. While it is readily available in numerous kinds, consisting of spots, lozenges, and tablets, the nasal spray solution is particularly designed 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 straight, bypassing the gastrointestinal system and the "first-pass metabolic process" of the liver. This leads to a quick start of action, usually within 5 to 10 minutes, making it ideal for treating acute flares of discomfort.
