https://en.m.wikipedia.org/wiki/Sufentanil https://en.m.wikipedia.org/wiki/Sufentanil This is the drug the article is talking about. >Sufentanil (R30730, brand name Sufenta) is a synthetic opioid analgesic drug approximately 5 to 10 times more potent than its parent drug, fentanyl, and 500 times as potent as morphine. Structurally, sufentanil differs from fentanyl through the addition of a methoxymethyl group on the piperidine ring (which is believed to reduce duration of action[2]), and the replacement of the phenyl ring by thiophene. Sufentanil first was synthesized at Janssen Pharmaceutica in 1974.[3] >Sufentanil is marketed for use by specialist centers under different trade names, such as Sufenta and Sufentil. Sufentanil with and without lidocaine or mepivacaine is available as a transdermal patch similar to Duragesic in Europe under trade names such as Chronogesic. It is available as a sublingual tablet under the trade name Dsuvia.[4] >Currently sufentanil is the strongest opioid painkiller available for use in humans. Although stronger narcotic pain medications do exist, all medications stronger than sufentanil are approved for veterinary use only.
