Betamethadol (INN), or β-methadol, also known as betametadol, is a synthetic opioid analgesic.^[2] It is an isomer of dimepheptanol (methadol), the other being alphamethadol (α-methadol).^[3] Betamethadol is composed of two isomers itself, L-β-methadol, and D-β-methadol.^[3] Based on structure-activity relationships it can be inferred that both isomers are likely to be active as opioid analgesics, similarly to those of betacetylmethadol (β-acetylmethadol).^[4]
