Novel drugs of abuse have been a growing problem for law enforcement and the medical profession. Consequently, they have also become a challenge for analysts in the face of new or variant chemicals.

To further complicate matters, CYP metabolism can either decrease or increase the blood levels of the active opioid, depending on the drug in question. Some opioids have no analgesic properties until ...

Pharmacokinetic research has shown that opioids with active metabolites can accumulate in frail older adults and patients with renal failure and can cause drowsiness, confusion and delirium.5 Opioids ...

The most common offenders amongst the active metabolites are the glucuronidated metabolites, such as morphine-3-glucuronide and hydromorphone-3-glucuronide. These metabolites are primarily ...

In our patient, blood concentrations of morphine metabolites, morphine-3-glucuronide, and morphine-6-glucuronide were substantially elevated, a finding likely to be attributable to renal failure ...

Since esterase enzymes in the blood rapidly convert heroin to morphine and 6-acetylmorphine through sequential deacetylation, scientists have, until now, identified the metabolites as better targets.
