times more potent than pethidine 15 and 72 times more potent than morphine 14. Alftentanil reaches its peak effect within 1 min after injection, and its duration of action is very short; at 2 times its MED50, 9r has a duration of action of 11 min. This duration is 30 min for 10 and 90 min for 14. Compared to 10, alfentanil 9r is about 4 times faster but 3 times shorter acting. Structurally, 9r shows
