  • Development of Pain-Free Methods for Analyzing 231 Multiclass Drugs and Metabolites by LC-MS/MS
    Clinical, Forensic & Toxicology Article “The Big Pain”: Development of Pain-Free Methods for Analyzing 231 Multiclass Drugs and Metabolites by LC-MS/MS By Sharon Lupo As the use of prescription and nonprescription drugs grows, the need for fast, accurate, and comprehensive methods is also rapidly increasing. Historically, drug testing has focused on forensic applications such as cause of death determinations or the detection of drug use in specific populations (military, workplace, probation/parole, sports doping). However, modern drug testing has expanded well into the clinical arena with a growing list of target analytes and testing purposes. Clinicians often request the analysis of large panels of drugs and metabolites that can be used to ensure compliance with prescribed pain medication regimens and to detect abuse or diversion of medications. With prescription drug abuse reaching epidemic levels [1], demand is growing for analytical methods that can ensure accurate results for comprehensive drug lists with reasonable analysis times. LC-MS/MS is an excellent technique for this work because it offers greater sensitivity and specificity than immunoassay and—with a highly selective and retentive Raptor™ Biphenyl column—can provide definitive results for a wide range of compounds. Typically, forensic and pain management drug testing consists of an initial screening analysis, which is qualitative, quick, and requires only minimal sample preparation. Samples that test positive during screening are then subjected to a quantitative confirmatory analysis. Whereas screening assays may cover a broad list of compounds and are generally less sensitive and specific, confirmation testing provides fast, targeted analysis using chromatographic conditions that are optimized for specific panels.

  • Big Pain Assays Aren't a Big Pain with the Raptor Biphenyl LC Column
    Featured Application: 231 Pain Management and Drugs of Abuse Compounds in under 10 Minutes by LC-MS/MS Big Pain Assays Aren’t a Big Pain with the Raptor Biphenyl LC Column • 231 compounds, 40+ isobars, 10 drug classes, 22 ESI- compounds in 10 minutes with 1 column. • A Raptor SPP LC column with time-tested Restek Biphenyl selectivity is the most versatile, multiclass-capable LC column available. • Achieve excellent separation of critical isobars with no tailing peaks. • Run fast and reliable high-throughput LC-MS/MS analyses with increased sensitivity using simple mobile phases. The use of pain management drugs is steadily increasing. As a result, hospital and reference labs are seeing an increase in patient samples that must be screened for a wide variety of pain management drugs to prevent drug abuse and to ensure patient safety and adherence to their medication regimen. Thera- peutic drug monitoring can be challenging due to the low cutoff levels, potential matrix interferences, and isobaric drug compounds. To address these chal- lenges, many drug testing facilities are turning to liquid chromatography coupled with mass spectrometry (LC-MS/MS) for its increased speed, sensitivity, and specificity. As shown in the analysis below, Restek’s Raptor Biphenyl column is ideal for developing successful LC-MS/MS pain medication screening methodologies. With its exceptionally high retention and unique selectivity, 231 multiclass drug compounds and metabolites—including over 40 isobars—can be analyzed in just 10 minutes. In addition, separate panels have been optimized on the Raptor Biphenyl column specifically for opioids, antianxiety drugs, barbiturates, NSAIDs and analgesics, antidepressants, antiepileptics, antipsychotics, hallucinogens, and stimulants for use during confirmation and quantitative analyses.
