Fentanyl is a highly potent opioid drug that’s approximately 75-100 times more potent than morphine, and has a rapid time to onset compared to many other opioids. This combination of high potency and rapid onset make fentanyl more likely to cause serious and potentially fatal reactions. In this video, I discuss the mechanism of fentanyl and what makes it different from other opioid drugs.
