Unlike many naturally obtained opiates, fentanyl is highly lipophilic (fat-soluble), which permits it to cross the blood-brain barrier rapidly. This results in a quick onset of action-- often within one to 2 minutes when administered intravenously-- making it a perfect choice for severe surgical procedures and emergency interventions.
The Significance of the "Citrate" Form
The "citrate" suffix refers to the salt kind of the drug. Fentanyl in its base kind is not easily soluble in water. By reacting it with citric acid to form fentanyl citrate, pharmaceutical manufacturers create a steady, water-soluble service suitable for parenteral (injectable) administration.

- Hypotension (low blood pressure).
- Urinary retention.
Severe Risks

- Dependency and Misuse: Like all opioids, fentanyl has a high capacity for dependence.
