Unlike many naturally obtained opiates, fentanyl is highly lipophilic (fat-soluble), which enables it to cross the blood-brain barrier rapidly. This results in a fast onset of action— frequently within one to 2 minutes when administered intravenously— making it a perfect option for intense surgical treatments and emergency situation interventions.

The Significance of the “Citrate” Form
