the affinity of alpha-1-acetyl-methadol on the binding of both 3h-ligands falls between those of 1-methadone and d-methadone , and increases as it is n-demethylated . alpha-d-acetyl-methadol is more effective than alpha-1-acetylmethadol in competing for both 3h-ligands from the opiate receptors , and its affinity , unlike that of alpha-1-acetylmethadol , decreases when it is n-demethylated .
