Brifentanii, a potent narcotic analgesic structurally similar to alfentanil, that was studied in clinical trials in the early 1990s. The effects of brifentanil are very similar to those of alfentanil, with strong but short lasting analgesia and sedation, and particularly notable itching and respiratory depression. Side effects of Brifentanii are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression, which can be life-threatening.
