Anileridine (trade name:Leritine) is a syntheticanalgesic drug[2] and is a member of thepiperidine class of analgesic agents[3] developed by Merck & Co. in the 1950s.[4] It differs frompethidine (meperidine) in that theN-methyl group of meperidine is replaced by anN-aminophenethyl group, which increases its analgesic activity.
Anileridine is no longer manufactured in the US or Canada.[5] Anileridine is in Schedule II of the Controlled Substances Act 1970 of the United States as ACSCN 9020 with a zero aggregate manufacturing quota as of 2014. The free base conversion ratio for salts includes 0.83 for the dihydrochloride and 0.73 for the phosphate.[6] It is also under international control per UN treaties.
Anileridine usually takes effect within 15 minutes of either oral or intravenous administration, and lasts 2–3 hours.[8] It is mostly metabolized by theliver.
