Levacetylmethadol is a narcotic analgesic with a long onset and duration of action. It is used mainly in the treatment of narcotic dependence. Levacetylmethadol was withdrawn from use in the European Union due to its high risk of QT interval prolongation. The production of levacetylmethadol in the US has ceased as well.

Opiate receptors (Mu, Kappa, Delta) are coupled with G-protein receptors and function as both positive and negative regulators of synaptic transmission via G-proteins that activate effector proteins. Binding of the opiate stimulates the exchange of GTP for GDP on the G-protein complex. As the effector system is adenylate cyclase and cAMP located at the inner surface of the plasma membrane, opioids decrease intracellular cAMP by inhibiting adenylate cyclase. Subsequently, the release of nociceptive neurotransmitters such as substance P, GABA, dopamine, acetylcholine and noradrenaline is inhibited. Opioids also inhibit the release of vasopressin, somatostatin, insulin and glucagon. Levomethadyl acetate effectively opens calcium-dependent inwardly rectifying potassium channels (OP1 receptor agonist), resulting in hyperpolarization and reduced neuronal excitability.
For the treatment and management of opiate dependence. It is sometimes used to treat severe pain in terminal patients.
