While it is available in numerous kinds, consisting of patches, lozenges, and tablets, the nasal spray solution is particularly designed for fast absorption through the nasal mucosa.
The nasal cavity is highly vascularised (rich in capillary), allowing the medication to enter the blood stream directly, bypassing the digestion system and the "first-pass metabolism" of the liver. This results in a fast onset of action, normally within 5 to 10 minutes, making it perfect for treating acute flares of pain.
