|---|---|---|---|
| Transdermal Patch | Through the skin | Durogesic, Matrifen | Persistent, steady pain (lasts 72 hours) |
| Buccal/Sublingual | Dissolved in the mouth | Abstral, Actiq, Effentora | Breakthrough cancer pain |
| Nasal Spray | Sprayed into the nose | Instanyl, PecFent | Quick relief of breakthrough discomfort |
| Injectable | Intravenous (IV) or Intramuscular (IM) | Generic Fentanyl | Surgery, ICU, emergency medication |
The Potency Factor: Comparing Opioids
To comprehend the clinical significance of fentanyl citrate, it is helpful to compare its potency to other opioids commonly utilized in the UK.
Table 2: Opioid Potency Comparison (Approximate)
| Opioid | Relative Potency (to Morphine) | Onset of Action (IV) |
|---|---|---|
| Morphine | 1 | 5-- 10 minutes |
| Oxycodone | 1.5-- 2 | 2-- 5 minutes |
| Hydromorphone | 5 | 2-- 5 minutes |
| Fentanyl Citrate | 50-- 100 | 1-- 2 minutes |

The UK Perspective on the "Opioid Crisis"
While the United Kingdom has not experienced an opioid crisis on the very same scale as the United States, there is growing concern regarding the rise in artificial opioid use.

- Never share medication: Fentanyl is calibrated for private tolerance; a dosage that is safe for one person could be fatal for another.
- Prevent heat sources: For those using spots, external heat (such as hot baths or electrical blankets) can increase the rate of drug absorption, leading to overdose.
