Term Description

This term represents the patient's drug level normalized for urine creatinine and lean body mass. It was created for, but not limited in use to, the Ameritox Medication Monitoring system, which assesses a patient's medication compliance by comparing the patient's result to a reference database of results from chronic pain patients who were known to be adherent to their medication regimen. In order to compare to the reference database, the patient's result is first normalized based on urine creatinine and lean body mass using a proprietary algorithm, and then the normalized result is converted to a Z-score based on the reference population.

Part Description

LP15015-8   Methadone
Methadone (also known as Symoron, Dolophine, Amidone, Methadose, Physeptone, Heptadon and many other names) is a synthetic opioid. It is used medically as an analgesic and a maintenance anti-addictive and reductive preparation for use by patients with opioid dependency. Because it is an acyclic analog of morphine, methadone acts on the same opioid receptors and thus has many of the same effects. Methadone is also used in managing severe chronic pain.
