While it is readily available in numerous kinds, including patches, lozenges, and tablets, the nasal spray solution is specifically developed for quick absorption through the nasal mucosa.

The nasal cavity is highly vascularised (abundant in capillary), permitting the medication to go into the blood stream straight, bypassing the digestive system and the “first-pass metabolic process” of the liver. This leads to a fast beginning of action, usually within 5 to 10 minutes, making it ideal for dealing with acute flares of discomfort.

Indicators for Use in the UK

How it Works: The Mechanism of Action
