While it is offered in different kinds, including patches, lozenges, and tablets, the nasal spray formula is specifically created for rapid absorption through the nasal mucosa.
The nasal cavity is highly vascularised (abundant in capillary), enabling the medication to go into the bloodstream straight, bypassing the digestion system and the "first-pass metabolism" of the liver.
