Fentanyl citrate is a rapid-acting, short-duration opioid agonist that interacts mainly with the μ-opioid receptors in the main nerve system. When administered by means of injection (either intravenously or intramuscularly), it offers extensive analgesia and sedation.
Unlike many naturally derived opiates, fentanyl is extremely lipophilic (fat-soluble), which permits it to cross the blood-brain barrier rapidly. This results in a fast start of action-- often within one to 2 minutes when administered intravenously-- making it a perfect option for intense surgical procedures and emergency interventions.
The Significance of the "Citrate" Form
The "citrate" suffix describes the salt form of the drug. Fentanyl in its base form is not quickly soluble in water. By reacting it with citric acid to form fentanyl citrate, pharmaceutical makers produce a steady, water-soluble service suitable for parenteral (injectable) administration.

- Addiction and Misuse: Like all opioids, fentanyl has a high potential for dependence.
