Description: 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. By binding to and activating opioid receptors in the central nervous sytem (CNS), anileridine mimics the endogenous opioids resulting in a decrease of nociceptve neurotransmitters and eventually an analgesic effect. Anileridine is discontinued.
