Pharmacology
IndicationUsed mainly in the treatment of narcotic dependence.
PharmacodynamicsMethadyl Acetate is a narcotic analgesic with a long onset and duration of action. The drug decreases a patients opioid use by preventing opioid withdrawal and in how it can mimic some of the effects of opioids.
Mechanism of actionMethadyl Acetate is primarily a mu-type opioid receptor agonist. It functions similarily to methadone.
