Methadyl Acetate is a narcotic analgesic with a long onset and duration of action. Methadyl Acetate is primarily a mu-type opioid receptor agonist and the drug decreases a patient's opioid use by preventing opioid withdrawal. Levacetylmethadol, the enantiomer of Methadyl Acetate, was approved in 1993 by the U.S. Food and Drug Administration for use in the treatment of opioid dependence. In 2001, levacetylmethadol was removed from the U.S. market due to reports of life-threatening ventricular rhythm disorders.
