With GC-MS as the preferred method and isotopically labeled analogs (ILAs) of the analytes as the internal standards (ISs) of choice for quantitative determination of drugs/metabolites in biological specimens, one important aspect associated with chemical derivatization (CD) is that the CD products derived from the analyte and the selected IS must generate ions suitable for designating the anal...

Benzodiazepines ameliorate or prevent the symptoms and complications of moderate to severe alcohol withdrawal, which can include autonomic hyperactivity, agitation, combativeness, hallucinations, seizures, delirium, and death. The benzodiazepines most commonly used for this purpose are lorazepam, chlordiazepoxide, oxazepam, and diazepam. It is widely asserted that no member of this group is sup...

Ethyl glucuronide (EtG) determination is increasingly used in clinical and forensic toxicology to document ethanol consumption. The enzymes involved in EtG production, as well as potential interactions with common drugs of abuse, have not been extensively studied. Activities of human liver (HLM), kidney (HKM), and intestinal (HIM) microsomes, as well as of 12 major human recombinant UDP-glucuro...

Previous studies have shown that drug concentrations in blood can change during storage, especially at room temperature, but even labile drugs such as cocaine may be stable in dried blood spots (DBS). A new method has been developed for the analysis of hydrolytically labile drugs in blood spots on filter paper in order to assess their degradation during a storage period of one month. The drugs ...
