Fentanyl citrate is a rapid-acting, short-duration opioid agonist that communicates primarily with the μ-opioid receptors in the main nerve system. When administered via injection (either intravenously or intramuscularly), it supplies profound analgesia and sedation.
Unlike numerous naturally derived opiates, fentanyl is extremely lipophilic (fat-soluble), which enables it to cross the blood-brain barrier rapidly. This results in a rapid beginning of action-- typically within one to 2 minutes when administered intravenously-- making it an ideal choice for intense surgical procedures and emergency situation interventions.
The Significance of the "Citrate" Form
