|---|---|---|---|
| Transdermal Patch | Through the skin | Durogesic, Matrifen | Persistent, stable discomfort (lasts 72 hours) |
| Buccal/Sublingual | Liquified in the mouth | Abstral, Actiq, Effentora | Advancement cancer discomfort |
| Nasal Spray | Sprayed into the nose | Instanyl, PecFent | Rapid relief of breakthrough discomfort |
| Injectable | Intravenous (IV) or Intramuscular (IM) | Generic Fentanyl | Surgical treatment, ICU, emergency medicine |
The Potency Factor: Comparing Opioids
To understand the clinical significance of fentanyl citrate, it is handy to compare its potency to other opioids typically used 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 actually not experienced an opioid crisis on the exact same scale as the United States, there is growing concern regarding the increase in artificial opioid use.

- Never share medication: Fentanyl is calibrated for private tolerance; a dosage that is safe for someone might be deadly for another.
- Prevent heat sources: For those utilizing patches, external heat (such as hot baths or electric blankets) can increase the rate of drug absorption, resulting in overdose.
