The distribution of i4C-toxiferine in rats ~as investigated using a combustion method in combination with whole-body autoradiograms at different time intervals after intravenous injection. The distribution is essentially the same as those of other non-depolarizing curare drugs. In
IntroductionNon-depolarizing curare alkaloids are metabolized only to a minimal extent in the organism [1,2,5,8,9]. Differences in duration of the effect of these alkaloids result from variations in distribution, binding and elimination. The following experiments were made to investigate the distribution of the long acting toxiferine in rats and compare the results with previous investigations on the distribution of the short-acting muscle relaxant N-N'-diallyl-bis-nor-toxiferine (Alcuronium = Alloferin| WASER and L/3THJ [9].
