While it is readily available in various types, including patches, lozenges, and tablets, the nasal spray formula is specifically created for fast absorption through the nasal mucosa.
The nasal cavity is extremely vascularised (abundant in blood vessels), allowing the medication to go into the blood stream directly, bypassing the digestion system and the "first-pass metabolism" of the liver.
