While it is offered in various types, consisting of spots, lozenges, and tablets, the nasal spray formula is particularly developed for quick absorption through the nasal mucosa.
The nasal cavity is highly vascularised (abundant in blood vessels), enabling the medication to get in the blood stream directly, bypassing the gastrointestinal system and the "first-pass metabolism" of the liver. This results in a rapid onset of action, typically within 5 to 10 minutes, making it ideal for dealing with severe flares of discomfort.
