While it is available in different kinds, consisting of patches, lozenges, and tablets, the nasal spray formula is particularly developed for rapid absorption through the nasal mucosa.
The nasal cavity is extremely vascularised (abundant in blood vessels), allowing the medication to get in the bloodstream directly, bypassing the gastrointestinal system and the "first-pass metabolic process" of the liver. This leads to a quick start of action, generally within 5 to 10 minutes, making it ideal for dealing with intense flares of pain.

How it Works: The Mechanism of Action

- Nasal Pathology: Patients with frequent nosebleeds or severe nasal damage should prevent this solution.

| Primary Use | Abrupt Breakthrough Pain | Gradual Breakthrough Pain | Persistent, Constant Pain |
| Duration | Short (approx. 1-2 hours) | Moderate (approx. 2-4 hours) | Long (72 hours) |
| Invasiveness | Non-invasive (Nasal) | Non-invasive (Oral) | Non-invasive (Skin) |
