Summary
This study presents simplified HPLC and GC/MS methods for detecting baclofen in blood and organs. These validated techniques are crucial for forensic, toxicological, and therapeutic monitoring, especially in intoxication cases.
Area of Science:
- Analytical Chemistry
- Forensic Toxicology
- Pharmacology
Background:
- Accurate quantification of baclofen in biological samples is essential for clinical and forensic applications.
- Existing methods for baclofen determination may require complex procedures or specialized equipment.
- Development of simpler, robust analytical techniques is needed for routine monitoring and post-mortem investigations.
Observation:
- High-performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (MS-MS) was optimized for quantitative baclofen analysis in blood.
- Gas chromatography coupled with mass spectrometry (GC/MS) was developed for qualitative baclofen detection in cadaveric organs.
- Method validation confirmed suitability for forensic medical analysis, clinical toxicology, and therapeutic drug monitoring.
Findings:
- The developed HPLC-MS-MS method provides a simpler and reliable approach for quantifying baclofen in blood.
- The GC/MS method enables accurate qualitative identification of baclofen in post-mortem organ tissues.
- Both methods demonstrated high sensitivity and specificity for baclofen detection.
Implications:
- These validated methods can enhance the accuracy and efficiency of baclofen monitoring in clinical settings.
- The techniques are valuable tools for forensic investigations, particularly in cases of suspected baclofen intoxication.
- Simplified analytical procedures may facilitate broader adoption in toxicology laboratories worldwide.
