title: Relative bioavailability in humans for oral tablets and solutions of lormetazepam.
abstract: A study was carried out to estimate the relative bioavailability of 7-chloro-5-(2-chlorophenyl)-3-hydroxy-1-methyl-1, 3-dihydro-1H-1,4-benzodiazepine-2-one (lormetazepam, Minias) in humans after administration of oral tablets and solutions. Plasma concentration of the drug was measured by gaschromatography with electron capture detector. Six healthy males were each given both formulations. With the oral solution higher plasma peak concentration and a shorter peak time were observed than with tablets. Also the elimination half-life was shorter with the oral solution, while no difference was found with the AUC.
