| Nasal Spray | Sprayed into the nose | Instanyl, PecFent | Quick relief of advancement pain |
| Injectable | Intravenous (IV) or Intramuscular (IM) | Generic Fentanyl | Surgical treatment, ICU, emergency situation medication |
The Potency Factor: Comparing Opioids
To comprehend the scientific significance of fentanyl citrate, it is valuable to compare its effectiveness to other opioids frequently 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 |
