Anileridine

Anileridine (trade name: Leritine) is a synthetic analgesic drug and is a member of the piperidine class of analgesic agents developed by Merck & Co. in the 1950s. It differs from pethidine (meperidine) in that the N-methyl group of meperidine is replaced by an N-aminophenethyl group, which increases its analgesic activity.
