Quantification of Loperamide by Gas Chromatography Mass Spectrometry.

Due to reported pharmacological activity similar to classical opioids at supratherapeutic concentrations, abuse of the anti-diarrheal medication loperamide (Imodium AD™) has become a target in the opioid epidemic. While this phenomenon is not new, published quantitative analytical methods use liquid chromatography tandem mass spectrometry. Described here is an 11 min method for quantification of loperamide in postmortem whole blood by gas chromatography mass spectrometry.

High urine ethanol and negative blood and vitreous ethanol in a diabetic woman: a case report, retrospective case survey, and review of the literature.

Several studies have shown that ethanol can be produced in urine infected with yeast or bacteria in vitro. We present the unusual case of a diabetic woman in whom ethanol was produced in her urine in vivo. The decedent was a 19-year-old woman who was noncompliant with her diabetes treatment.

Polydrug fatality involving metaxalone.

A 29-year old female with a history of depression was found dead in a hotel room. The death scene investigation found empty pill bottles and an empty liter bottle of wine. Metaxalone, a centrally acting muscle relaxant, along with citalopram, ethanol, and chlorpheniramine were identified in the postmortem samples and quantitated by gas chromatography-mass spectrometry.
