Table 1: Common Strengths of Fentanyl Sublingual Tablets in the UK
| Strength (Micrograms) | Typical Colour/Marking | Use Case |
|---|---|---|
| 100 mcg | Differs by maker | Initial starting dose for titration |
| 200 mcg | Differs by manufacturer | Intermediate titration step |
| 300 mcg | Differs by maker | Intermediate titration action |
| 400 mcg | Varies by manufacturer | Advanced titration step |
| 600 mcg | Varies by manufacturer | High-dose development relief |
| 800 mcg | Differs by manufacturer | Maximum basic single dosage |
System of Action: How it Works
Fentanyl is a pure opioid agonist that binds mainly to the mu-opioid receptors in the central nervous system (brain and spinal cord).
- Absorption: Upon positioning under the tongue, the tablet dissolves in the saliva. The highly lipophilic (fat-soluble) nature of fentanyl allows it to pass rapidly through the mucosal membrane.
