Fentanyl is a synthetic opiate analgesic with a rapid onset and short duration of action. It is a strong agonist at the μ-opioid receptors and is historically used to treat breakthrough pain. Fentanyl is approximately 100 times more potent than Morphine, and is commonly used as a patch. Sometimes used as an adulterant for heroin, which has led to many overdose deaths.
