Term Description

This term represents the Z-score for a patient's drug result. 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. If the patient's Z-score is between -2 and +2, the patient is likely to be taking the drug as prescribed. If the score is less than -2, the patient's drug level is lower than expected, which could be a sign that the patient stopped taking the drug or has altered metabolism. If the score is greater than +2, the patient's drug level is higher than expected, which could occur for a number of reasons, including overuse of the drug or impaired metabolism due to liver or kidney disease.

Part Description

LP15003-4   oxyCODONE
Oxycodone is a potent and addictive opioid analgesic medication synthesized from thebaine. Its name is derived from codeine, which has a very similar chemical structure. It is effective orally and is marketed in combination with acetylsalicylic acid (Percodan, Endodan, Roxiprin) or paracetamol (Percocet, Endocet, Roxicet, Tylox) for the relief of pain. More recently, ibuprofen has been added to oxycodone (Combunox). Long term users may develop a tolerance or resistance to the drug. Abusers crush the tablets and injest the powder orally, intranasally, or via intravenous, intramuscular or subcutaneous injections.
