Levomethadyl Acetate (also known as levacetylmethadol or levo-α-acetylmethadol) (LAAM), is a synthetic opioid structurally similar to methadone. It is an opioid agonist that has been used as an analgesic and to treat opioid dependence. Levomethadyl Acetate is metabolized by cytochrome P450 3A4 in two N-demethylation reactions to nor-levomethadyl acetate (nor-LAAM) and subsequently to dinor-levomethadyl acetate (dinor-LAAM).
