While it is available in numerous forms, including patches, lozenges, and tablets, the nasal spray formula is specifically created for fast absorption through the nasal mucosa.
The nasal cavity is highly vascularised (abundant in capillary), permitting the medication to get in the bloodstream straight, bypassing the digestion system and the "first-pass metabolism" of the liver. This results in a fast beginning of action, normally within 5 to 10 minutes, making it ideal for treating severe flares of discomfort.
