Pharmacogenomics, the study of the impact of heritable traits on pharmacology and toxicology, may serve as an adjunct for certifying opioid fatalities. Oxycodone, frequently prescribed for the relief of moderate to severe pain, is metabolized by cytochrome P450 (CYP) 2D6, encoded by a polymorphic gene with three mutations (*3, *4, and *5) with a combined(More)
Pharmacogenomics, applied as an aspect of molecular autopsy, may be used as an adjunct for certifying methadone fatalities. Methadone is metabolized by cytochrome P-450 (CYP) 1A2, 3A4, and 2D6. We hypothesized that methadone toxicity may be partially due to CYP 2D6 *3, *4, and *5 variant alleles, resulting in poor drug metabolism. A retrospective analysis(More)
This report describes two cases of acute zolpidem overdose. The decedent in the first case was a 36-year-old female found dead in bed in her secured home. She had a history of psychiatric illness, including paranoid disorder, depression with panic episodes, and post-traumatic stress disorder. She was treated with risperidone and sertraline. Nine months(More)
The phenylalkylamine derivatives, 3,4-methylenedioxymethamphetamine (MDMA, ecstasy, XTC, Adam), 3,4-methylenedioxyethamphetamine (MDEA, MDE, Eve), and 3,4-methylenedioxyamphetamine (MDA), are psychostimulants with hallucinogenic properties. MDA is also a metabolite of both MDMA and MDEA. These drugs are ring-substituted amphetamine derivatives that produce(More)
Pharmacogenomics, the study on genetic contributions to drug action may help in certifying fentanyl toxicity. Fentanyl is used clinically as an adjunct to surgical anesthesia and for chronic pain management. Its toxicity may be partially due to cytochrome P450 (CYP) 3A4*1B and 3A5*3 variant alleles, resulting in variable fentanyl metabolism. In this study,(More)
The performance of the new fluorescence polarization immunoassay reagents Cassette COBAS INTEGRA Serum Benzodiazepines assay (SBENZ) and Cassette Serum Barbiturates assay (SBARB) was evaluated as compared to other immunoassays (Abbott TDx Serum Benzodiazepines, Abbott TDx Urine Benzodiazepines, Behring EMIT Serum Benzodiazepines, Abbott ADx Serum(More)
syndrome, was treated with methyl phenidate, clonidine and fluoxetine [10]. Over a 10‐month period, he developed gastrointestinal toxicity, incoordination and disorientation, and sei‐ zures. He died from a cardiac arrest. Post‐ mortem toxicology showed high fluoxetine and norfluoxetine concentrations, and PGx revealed a poor CYP2D6 metabolizer geno‐ type,(More)
A 36-year-old Caucasian male was found unresponsive by his wife. He had white foam around his mouth and was pronounced dead shortly thereafter. He had a history of back pain and was treated with intrathecal morphine because of his previous addiction to oral opiate medications. Because of crimping of the pump catheter, it was replaced 4 days before his(More)
The authors evaluated a new Cassette Serum Barbiturates fluorescence polarization immunoassay (FPIA) on the COBAS INTEGRA. The assay was calibrated with secobarbital standards at 0, 0.5, and 4.0 microg/mL. The assay range was 0.030 to 80 microg/mL using an automatic 1/20 postdilution feature. Precision was established for two COBAS INTEGRA instruments for(More)
