'''Fentanyl''' is an opioid used for analgesia.
'''Fentanyl''' is a synthetic, lipophilic phenylpiperidine opioid agonist used for analgesia. It is highly lipophilic leading to fast passage across the blood-brain barrier with a 6.8 minute onset time. Fentanyl will also rapidly redistribute to adipose and fatty tissue leading to a short duration of action.
