• The 50% effective doses of five barbiturate-β-cyclodextrin complexes on oral administration to mice were compared with those of the corresponding barbiturates. In all cases tested, the complex gave a smaller ED_<50> than the intact drug. ED_<50> of phenobarbital, which forms the most stable complex and consequently shows the greatest enhancement in solubility, was reduced most markedly by complexation. With the exception of barbital, sleeping lag (the time from oral administration to loss of righting reflex) on administration of the complex to mice was shorter than that on giving an equimolar amount of the intact drug (p<0.001), and sleeping time (the time from loss to recovery of righting reflex) was significantly increased by inclusion complexation with β-cyclodextrin.
