What is fentanyl?

Fentanyl, also known as fentanil, is an opioid pain medication with a rapid onset and short duration of action. It is a potent agonist of μ-opioid receptors. Fentanyl is 50 to 100 times more potent than morphine, but some fentanyl analogues, which are designed to mimic the pharmacological effects of the original drug, may be as much as 10,000 times more potent than morphine.
