“…Following the incubation, the antibodybound radioligand was separated from the unbound fraction by precipitation with saturated ammonium sulfate (7). After the pellet was dissolved in 0.4 ml of water and 3 ml of scintillator6 to give a clear solution, radioactivity in each tube was quantified in a modified liquid scintillation counter as described previously (8).…”

“…einer direkten Beeintrfichtigung der Fahrerleistung. In den vergangenen Jahren sind fur Benzodiazepine nur wenige Immunoassays beschrieben worden [7,9,10,12,16,18]. Abgesehen vo.n der relativ geringen Empfindlichkeit dfinnschichtchromatographischer Methoden, die ft~r die Urinanalyse zunfichst in Betracht kommen, sagt ein nachgewiesener Benzodiazepin-Gehalt im Urin verhfiltnism~iBig wenig fiber eine aktuelle Blutkonzentration bei dem betreffenden Anwender aus [3].…”

“…Bislang wurde von uns ffir den ungezielten Nachweis einer vorangegangenen Einnahme die dfinnschichtchromatographische Analyse von Benzodiazepin-Hydrolyseprodukten im Urin benutzt. Die entsprechenden Assays (Chlordiazepoxid [10], Diazepam [7,12,18], Clonazepam [9]) besitzen eine hohe Spezifitfit ffir die jeweils in Frage stehende Substanz. Rechnet man mit einer langdauernden Urinausscheidung von Stoffwechselmetaboliten, besonders von Nl-desalkylierten Benzodiazepinen, welche h~iufig kumulieren [22], so braucht damit nicht notwendigerweise ein Blutspiegel verbunden zu sein, der mit pharmakologischen Wirkungen in Verbindung zu bringen wfire.…”

“…Unlike other commonly administered benzodiazepines, chlordiazepoxide can not be reliably quantitated by gas-liquid chro matographic methods, since the parent com pound and its metabolites undergo rear- rangement and/or fragmentation at column temperatures required for analysis [3], Radio immunoassay [4] and spectrofluorometric [5] methods have been previously used for quan titation, but these methods have limitations. Immunoassay does not allow for the separa tion and simultaneous quantitation of both the parent compound and its active metabo lites.…”
