Weldon Bellville A1 Terence Murphy A1 William S. Howland YR 1960 UL http://jpet.aspetjournals.org/content/130/3/364.abstract AB The potency ratio of thiopental and a 3:1 mixture of thiopental + β,β-ethylmethylglutarimide has been determined in seven dogs by a servo-controlled, cross-over experiment employing the electroencephalogram as an index of drug action. Thiopental was found to be 1.51 times as potent as thiopental plus β,β-ethylmethylglutarimide. The upper and lower 95% confidence limits were 2.3 and 1.1, respectively.
