Fentanyl is a powerful synthetic and short-acting painkiller that is 50-100 times more potent than morphine, meaning that 1/10th of a gram of fentanyl is equivalent to between 5-10g of morphine. It was first synthesized by Dr. Paul Janssen in December 1960 and has become one of the world’s most important and frequently used opioid analgesics, used also as a pre-medication for general anaesthetic, partly because of its rapid action and multiple routes of administration.
