Betamethadol (INN) or β-methadol also known as betametadol is a synthetic opioid analgesic. It is an isomer of dimepheptanol (methadol) the other being alphamethadol (α-methadol). Betamethadol is composed of two isomers itself L-β-methadol and D-β-methadol. 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).
