Plasma concentrations of 5-(2-chlorophenyl)-7-ethyl-1,3-dihydro-1-methyl-2H-thieno[2,3-e][1,4]diazepin-2 -one (clotiazepam, CTZ, Trecalmo), a thienodiazepine anti-anxiety agent, and two of its metabolites (hydroxy- and desmethyl-clotiazepam) are reliably quantified by electron capture GLC. After addition of diazepam as internal standard, 1-ml plasma samples are extracted with
