• Clinical and Forensic Toxicology
• Drugs of Abuse
• Pharmacokinetics and Toxicokinetics
Our principle areas of research are analytical, clinical and forensic toxicology. In our basic research we develop new methods to detect drugs and their metabolites in biological fluids and tissues. These have significant applications in developing new drug delivery systems and determination of drug pharmacokinetic parameters. Our laboratory is part of the William L. Jenkins Forensic Center. In performing analyses for our Medical Examiners, these techniques are used to determine therapeutic, toxic and fatal drug concentrations in biological specimens from the deceased as well as the effects of postmortem distribution and redistribution. Determination of significant drug interactions has been a specific interest of our lab. Several of our investigations have been the first reported cases of fatal drug interactions.
Since we are involved with clinical and forensic drug analysis of biological specimens to determine human psychomotor impairment and drug abuse, our research has taken us into development of methods to detect urine adulterants (substances used to produce false negative test results) and the extent of their effects on drug screening and confirmation techniques. We have developed capillary electrophoretic and colorimetric techniques to detect and confirm ionic adulterants such as nitrates and chromates as well as other anions and cations. Investigation of the hindrance by papain (meat tenderizer) of the detection and confirmation of marihuana metabolites has recently revealed that the mechanism of this adulterant is nonspecific binding to the analyte. The impact of papain on urine drug screening and the detection and confirmation of papain warrants further research.
More recent research has been on determining the impact of alcohol and drugs, especially opiates and benzodiazepines, in the lethal forensic cases we have investigated over the past six years at our forensic center. Identification of trends in these cases can help us determine the causes and origins for these drugs’ fatal impact in our society. We have also been researching the effects of fire on ethanol and ethyl glucuronide concentrations in postmortem specimens.
A complete list of our numerous areas of research and all our collaborators can be found at our web site (http://www.etsu.edu/com/dbms/facilities/toxicology.aspx ).
Our lab supports the various hospitals, clinics and programs associated with the James H. Quillen College of Medicine.
