Trendy specialists clarify the pharmacology and metabolism of benzodiazepines (LDB) and g-hydroxybutyric acid (GHB) and provide strong and potent methodologies that would allow larger detection of those medicinal drugs in a variety of physique fluids, in addition to in hair. The options contain hugely delicate immunoassay detection of LDBs, the detection of Rohypnol® and different LDBs through mass spectrometry, and the ultrasensitive detection of GHB. cutting-edge and hugely useful, Benzodiazepines and GHB: Detection and Pharmacology bargains toxicologists, forensic scientists, and medical chemists modern best equipment for detecting those generally abused medications which are occasionally stumbled on linked to felony acts.
