Alphamethadol
Synthetic opioid analgesic drug
From Wikipedia, the free encyclopedia
Alphamethadol (INN), or α-methadol, also known as alfametadol, is a synthetic opioid analgesic.[2] It is an isomer of dimepheptanol (methadol), the other being betamethadol (β-methadol).[3] Alphamethadol is composed of two isomers itself, L-α-methadol, and D-α-methadol.[3] Both of alphamethadol's isomers bind to and activate the μ-opioid receptor and are active as opioid analgesics,[4] similarly to those of alphacetylmethadol (α-acetylmethadol).[5]
